What these people are referring to is their personality type based on the Myers-Briggs Type Indicator (MBTI). The Myers-Briggs Personality Type Indicator is a self-report inventory designed to identify a persons personality type, strengths, and preferences. The questionnaire was developed by Isabel Myers and her mother Katherine Briggs based on their work with Carl Jungs theory of personality types. Today, the MBTI inventory is one of the most widely used psychological instruments in the world. The Development of the Myers-Briggs Test Both Isabel Myers and her mother Katherine were fascinated by Jungs theory of psychological types and recognized that the theory could have real-world applications. During World War II, Myers and Briggs began researching and developing an indicator that could be utilized to help understand individual differences. By helping people understand themselves, Myers and Briggs believed that they could help people select occupations that were best suited to their personality types and lead healthier, happier lives. Myers created the first pen-and-pencil version of the inventory during the 1940s, and the two women began testing the assessment on friends and family. They continued to fully develop the instrument over the next two decades. An Overview of the Test Based on the answers to the questions on the inventory, people are identified as having one of 16 personality types. The goal of the MBTI is to allow respondents to further explore and understand their own personalities including their likes, dislikes, strengths, weaknesses, possible career preferences, and compatibility with other people. No one personality type is best or better than any other one. It isnt a tool designed to look for dysfunction or abnormality. Instead, its goal is simply to help you learn more about yourself. The  questionnaire itself is made up of four different scales: Extraversion (E) - Introversion (I) The extraversion-introversion dichotomy was first explored by Jung in his theory of personality types as a way to describe how people respond and interact with the world around them. While these terms are familiar to most people, the way in which they are used here differs somewhat from their popular usage. Extraverts (also often spelled extroverts) are outward-turning and tend to be action-oriented, enjoy more frequent social interaction, and feel energized after spending time with other people. Introverts are inward-turning and tend to be thought-oriented, enjoy deep and meaningful social interactions, and feel recharged after spending time alone. We all exhibit extraversion and introversion to some degree, but most of us tend have an overall preference for one or the other. Sensing (S) - Intuition (N) This scale involves looking at how people gather information from the world around them. Just like with extraversion and introversion, all people spend some time sensing and intuiting depending on the situation. According to the MBTI, people tend be dominant in one area or the other. People who prefer sensing tend to pay a great deal of attention to reality, particularly to what they can learn from their own senses. They tend to focus on facts and details and enjoy getting hands-on experience. Those who prefer intuition pay more attention to things like patterns and impressions. They enjoy thinking about possibilities, imagining the future, and abstract theories. Thinking (T) - Feeling (F) This scale focuses on how people make decisions based on the information that they gathered from their sensing or intuition functions. People who prefer thinking place a greater emphasis on facts and objective data. They tend to be consistent, logical, and impersonal when weighing a decision. Those to prefer feeling are more likely to consider people and emotions when arriving at a conclusion. Judging (J) - Perceiving (P) The final scale involves how people tend to deal with the outside world. Those who lean toward judging prefer structure and firm decisions. People who lean toward perceiving are more open, flexible, and adaptable. These two tendencies interact with the other scales. Remember, all people at least spend some time extraverting. The judging-perceiving scale helps describe whether you extravert when you are taking in new information (sensing and intuiting) or when you are making decisions (thinking and feeling). Each type is then listed by its four letter code: ISTJ - The InspectorISTP - The Crafter ISFJ - The ProtectorISFP - The ArtistINFJ - The AdvocateINFP - The MediatorINTJ - The ArchitectINTP - The ThinkerESTP - The PersuaderESTJ - The DirectorESFP - The PerformerESFJ - The CaregiverENFP - The ChampionENFJ - The GiverENTP - The DebaterENTJ - The Commander Taking the Myers-Briggs Type Indicator can provide a lot of insight into your personality, which is probably why the instrument has become so enormously popular. Even without taking the formal questionnaire, you can probably immediately recognize some of these tendencies in yourself. According to the Myers Briggs Foundation, it is important to remember that all types are equal and that every type has value. When working in group situations in school or at work, for example, recognizing your own strengths and understanding the strengths of others can be very helpful. When you are working toward completing a project with other members of a group, you might realize that certain members of the group are skilled and talented at performing particular actions. By recognizing these differences, the group can better assign tasks and work together on achieving their goals. How Myers-Briggs Type Indicator Differs From Other Personality Instruments First, the MBTI is not really a test. There are no right or wrong answers and one type is not better than any other type. The purpose of the indicator is not to evaluate mental health or offer any type of diagnosis. Also, unlike many other types of psychological evaluations, your results are not compared against any norms. Instead of looking at your score in comparison to the results of other people, the goal of the instrument is to simply offer further information about your own unique personality. Reliability and Validity According to the Myers Briggs Foundation, the MBTI meets accepted standards of reliability and validity. However, other studies have found that the reliability and validity of the instrument have not been adequately demonstrated. Studies have found between 40 and 75 percent of respondents receive a different result after completing the inventory a second time. A 1992 book by The Committee on Techniques for the Enhancement of Human Performance and the National Research Council suggests that ...there is not sufficient, well-designed research to justify the use of MBTI in career counseling programs. Much of the current evidence is based on inadequate methodologies. The MBTI Today Because the Myers-Briggs Personality Type Indicator is relatively easy to use, it has become one of the most popular psychological instruments currently in use today. Approximately two million U.S. adults complete the inventory each year. While there are many versions of the MBTI available online, it should be noted that any of the informal questionnaires that you may find on the Internet are only approximations of the real thing. The real MBTI must be administered by a trained and qualified practitioner that includes a follow-up of the results. Today, the questionnaire can be administered online via the instrument publisher, CPP, Inc., and includes receiving a professional interpretation of your results. The current version of the Myers-Briggs Type Indicator includes 93 forced-choice questions in the North American version  and 88 forced-choice questions in the European version. For each question, there are two different options from which the respondent must choose.

The Freedom of Slaves - Free Essay Example

The year 1775 was when John Murray organized a colonial military unit called the Ethiopian Regiment that had over 30,000 black slaves who leave their masters to join their organization. They were promised freedom if they joined Lord Dunmore to fight against the rebels in the revolutionary war, many of them however, died or were sent back to their masters. Not only did these slaves risk their lives in order to gain their freedom, they also risked punishment from their owners if they were to get sent back. Therefore not all slaves were able to benefit much from joining this Regiment. What the military has solved was them being known as the most skilled, equipped soldiers with naval superiority. Slaves were also freed due to the Revolution. Many black slaves died due to diseases such as smallpox and only 300 were able to contribute while the rest were thrown out of their boat or sent to jail. Based on the primary documentation that was sent to Lord Dunmore, colonial governor in the American colonies; freeing black slaves after they fight for the British played a major role for the American Revolution and their strategy. Furthermore, this started a practice that led to events, such as Dunmores issues with the Patriots. He was in need of troops and later started enlisting any free man. This resulted to his recruitment of black slaves and of other origins. The letter was sent from the Council of Virginia, a reply to the Governors message congratulating the arrival of him and his family as well as concur with the House Of Burgesses in framing such laws as shall be for the welfare and true interest of this colony . Lord Dunmores contribution helped the colony build a stronger union as well as events leading up to it, such as the Tea Act. People from the North suspected the war would be unavoidable when the Coercive Acts was passed. However, Lord Dartmouth anticipated against hope for peace and willingly wanted to discuss further notion with the American Congress. Thus, he proposed for the colonies to signify their adherence to the imperial trade laws by reenacting those statutes . John Ferling describes the decisions being made by the congress and people, such as John Adams, who was against the idea of going to war and Congresss second pivotal step was to urge each colony to put its militia upon a proper footing . Therefore, Adams claimed that Congress would neither create a national army nor assist the colonies in preparing their militias. These events have affected black slaves due to the union being in need of recruits. They offered black slaves to gain their freedom in exchange for them to participate in their military union. Blacks were anxious to join the war due to an act of congress, it declared that the soldier that enlisted would be free forever, as well as their mother, wife, and children. The chance to fight outside of the union was also seen as an opportunity to prove themselves as people seeing as during that time period they were treated poorly due to their ethnicity. In Slave Nation: How Slavery United the Colonies Sparked the American Revolution, the authors argue about the role slaves take in the founding of the republic, from the Declaration of Independence to the making of the constitution. Such as, the year 1776 when Thomas Jefferson proposed to abolish the slave act as well as an end to existing property rights of primogeniture. Alfred and Ruth gave detailed evidence in order to support their arguments and suggestions, since he opposed the concept of slavery, but instead modified the Declaration of Independence and removed the word property to liberty . Another important event that shaped the union and impacted slaves was the Somerset case which was the cause of the American Revolution. Lord Mansfield declared a judgement in the Somersets Case that affirmed that slavery was at odds with the English law and that no one can impose authority on slaves in Scotland or England. The case began to completely abolish the slave trade, however it was not until the Slavery Abolition Act of 1833 that Slavery was extinguished around all the British Empire. The author of Slave Nation also revealed how much the British as well as the Americans relied on the black slaves before the Tea Act. They were used to cash crops such as tobacco, cotton, sugar, rice, etc. Moreover, documents such as the Declaration of Independence, played a major role during that time period. According to Thomas Jefferson he estimates that 30,000 slaves walked off their plantation to fight in the Revolution. However, there were some black slaves who did not have the choice to fight and were not guaranteed the freedom from the constitution. The book demonstrated important events that occurred in 1776 where Jefferson proposed an end to existing property rights of primogeniture and was able to solve the problem by using language that was more general. There are events where it goes more into what went on once they declared Independence and the debate they had. Peter Van Schaack, a loyalist from New York, claimed that British treatment of its colonies is harsh which is how they have met those conditions of being governed[4]. Later on blacks gained recognition and were starting to be looked at differently since it was in the middle of a time period where every black person was looked down on because of their status. Furthermore, they were being used by the British and took advantage of the wartime confusion to migrate to other areas of the colonies. The British may have lost the war but they were still known as the most powerful country in the world due to their skilled and professional soldiers. The Americans only won the war only because they were aided by the French king who was opposed to offering the same liberties to his people . Alfred and Ruth Blumrosen explain further in Slave Nation that the main focus was slaves being the motor of the Revolution and how to resolve their issue being internal liberty with the north on freedom from taxation by England. In addition, an important event that led to the abolishment of black slaves was the Somerset case in the American colonies and the laws being made throughout the years since many slaves walked away from their masters. However, in 1778 when Virginia outlawed the importation of slaves it took years until slaves were abolished. Some slaves were being abolished immediately in the North by the constitution, but in 1776 was when Vermont writes a constitution in which slavery was eradicated. Whereas in Boston, Massachusetts, the abolishment of slavery did not go through until a slave sued the state. Another point that was brought up by Alfred and Ruth Blumrosen was how slavery united the 13 colonies and how America was built on a compromise on slavery and if it were not for the northern states not assenting to the southern demands there would be no nation, seeing as the souths economy is based on plantation . The attitudes of these men were influenced by the nature of the planting process and them being known as a successful tobacco grower was a personal achievement and considered it their independence. The author Raphael from the book The First American Revolution: Before Lexington and Concord, points out during late August of 1774, patriots and British officials geared up for the court openings. They went further to discuss the rumor that British troops bombarded Boston and heard shots fired that resulted to six men being killed. Congress knew that war was coming and Britain was in need of more troops. Thomas Gage was assigned as a British Army General Soldier was served for North America, he was the most convincing witness to the power of the Massachusetts Revolution of 1774. In his letters he sent that fall to Lord Dartmouth he chronicled activities of his opponents, referring often to the proceedings of the Provincial Congress. The author Ray mentioned how Massachusetts chose to mix black and white soldiers and afterwards thousands of black soldiers were sold in the West Indies making $1,000 for each one of them. It was not until 200 years and another civil war before blacks were given the guarantees of the constitution to be freed. Most people during that time period did not have an explanation of slavery and took black slaves for granted especially for all the work they have done previously such as working in the field with tobacco, cotton, and sugar. Even though these measures slavery was disappearing in the North and not in the South. Washington would be having a formal meeting with Congress discussing when reports of the reverses in Georgia arrived and were promptly referred to the committee. Negroes sufficient for Pioneers, servants all fatigue Duty by Land Water and Negroes who may be armed. as high as thirty five hundred thousand . The fear that Washington had was that the British might draw significant strength by arming American slaves. It first surfaced with Governor Dunmores proclamation in 1775. Nonetheless Dunmore had been operating from a ship in Chesapeake Bay, and until the British were able to remain in the south they ability to exploit such efforts was said to be limited. Thus the new southern strategy rested on appealing to loyalist, not slaves. Once the news from Georgia reached Congress some delegates assumed that they would arm black soldiers. The greatest source of Danger, is the accession of strength of strength they will probably receive, from the black inhabitants, one Maryland delegate wrote, and if they are resolved to prosecute the Measure, and to break through every tie of honor and Humanity, they will gain considerable strength. it was open question whether British would act more as liberators or as plunderers or new exploiters . All in all, due to the occurrence of the American Revolution thousands of slaves were freed, there were also more blacks freed from the aftermath of the Revolution than any other war prior to that. Britain saw them as toys who were used to fight for the Empire on a condition being that they could be granted their freedom in exchange for taking arms. The slaveholders of the south did not however plan on giving weapons to the black slaves in fear that they would turn against their owners. Thus the northerners armed black slaves due to them having too much to do and to keep the farm going. Events such as the Somerset case that initiated the American Revolution also brought slaves to fight not only for their independence but for themselves and to be recognized as individuals rather than as objects. Conclusion While the Revolution responded to a variety of issues what really motivated the slaves was the decision in determining which side would result to their freedom the fastest. Many black slaves played a major role during this time period, both free and enslaved. Additionally, the American Revolution played a large role in defining the institution of slavery in the American colonies, but it also impacted the global slave trade for years to come. As a result Americans and British would not be here if it were not for the black slaves and how they were able to contribute in using both their farming and skills used in war.

Post World War II Migration to the Suburbs Free Essay Example, 2500 words

Were fighting in the World War II sought a place to live, as they started obtaining peacetime jobs and earning a living in different ways, as opposed to fighting on the battlefronts (Garnett, 285). In their attempt to earn a living, the soldiers and war veterans could not find sufficient accommodation in the urban areas, due to the shortage of housing in the urban regions. This being the case, the war veterans had to seek for a place to live, which was not far from the urban areas, and thus would allow them to commute from the urban areas where they were working in industries and other sectors back to their homes (Stahura, 317). This led to the development of various suburbs in close proximity to the main towns and cities. This saw a move from the urban areas to the suburbs, which was not only meant for the War veterans, but also for the other urban residents who found that the suburbs had developed close to the urban areas, and therefore it was easy for them to commute to and from the suburbs.

Arizona State University Acceptance Rate, SAT/ACT Scores, GPA

Arizona State University is a public research university with an acceptance rate of 85%. The university is one of five unique ASU campuses located throughout Phoenix: the main campus in Tempe, the Downtown Campus in Phoenix, the West Campus in Phoenix, the Polytechnic Campus in Mesa, and the Colleges at Lake Havasu City. The Tempe campus has over 51,000 students and is one of the largest universities in the country. Arizona State has well-respected academic programs in Business and Engineering. It was also awarded a chapter of  Phi Beta Kappa  for its strengths in the liberal arts and sciences. The Arizona State Sun Devils compete in the NCAA Division I  Pacific 12 Conference. Considering applying to Arizona State University? Here are the admissions statistics you should know, including average SAT/ACT scores and GPAs of admitted students. Acceptance Rate During the 2017-18 admissions cycle, Arizona State University had an acceptance rate of 85%. This means that for every 100 students who applied, 85 were admitted, making ASUs admissions process less competitive. Admissions Statistics (2017-18) Number of Applicants 26,869 Percent Admitted 85% Percent Admitted Who Enrolled (Yield) 39% SAT Scores and Requirements Arizona State requires that all applicants fulfill aptitude requirements. These requirements can be demonstrated by class rank (top 25%), average GPA of 3.0 in competency courses, an SAT score of 1120 or above (residents), or 1180 or above (nonresidents), or an ACT score of 22 or above (residents), or 24 or above (nonresidents). Some degree programs have higher SAT/ACT requirements. During the 2017-18 admissions cycle, 60% of admitted students submitted SAT scores. SAT Range (Admitted Students) Section 25th Percentile 75th Percentile ERW 570 670 Math 560 690 ERW=Evidence-Based Reading and Writing This admissions data tells us that most of Arizona States admitted students fall within the top 35% nationally on the SAT. For the evidence-based reading and writing section, 50% of students admitted to ASU scored between 570 and 670, while 25% scored below 570 and 25% scored above 670. On the math section, 50% of admitted students scored between 560 and 690, while 25% scored below 560 and 25% scored above 690. Applicants with a composite SAT score of 1360 or higher will have particularly competitive chances at Arizona State University. Requirements ASU does not require the SAT writing section or SAT Subject tests. Note that Arizona State participates in the scorechoice program, which means that the admissions office will consider your highest score from each individual section across all SAT test dates. ACT Scores and Requirements Arizona State requires that all applicants fulfill aptitude requirements. These requirements can be demonstrated by class rank (top 25%), average GPA of 3.0 in competency courses, an SAT score of 1120 or above (residents), or 1180 or above (nonresidents), or an ACT score of 22 or above (residents), or 24 or above (nonresidents). Some degree programs have higher SAT/ACT requirements.During the 2017-18 admissions cycle, 58% of admitted students submitted ACT scores. SAT Range (Admitted Students) Section 25th Percentile 75th Percentile English 21 29 Math 22 28 Composite 22 29 This admissions data tells us that most of Arizona States admitted students fall within the top 37% nationally on the ACT. The middle 50% of students admitted to ASU received a composite ACT score between 22 and 29, while 25% scored above 29 and 25% scored below 22. Requirements Arizona State does not require the ACT writing section. Unlike many universities, ASU superscores ACT results; your highest subscores from multiple ACT sittings will be considered. GPA In 2018, the mean high school GPA of Arizona State Universitys incoming freshman class was 3.54. This information suggests that most successful applicants to ASU have primarily B grades. Self-Reported GPA/SAT/ACT Graph Arizona State University Applicants Self-Reported GPA/SAT/ACT Graph. Data courtesy of Cappex. The admissions data in the graph is self-reported by applicants to Arizona State University. GPAs are unweighted. Find out how you compare to accepted students, see the real-time graph, and calculate your chances of getting in  with a free Cappex account. Admissions Chances Arizona State University, which accepts over three-quarters of applicants, has a slightly selective admissions process. If you have completed the course competency and aptitude requirements you have a strong chance of being accepted. ASU requires all applicants to have four years of English and math, 3 years of laboratory science and social studies, 2 years of the same foreign language, and 1 year of fine arts or technical education. In addition to course requirements, ASU applicants must demonstrate aptitude by class rank, GPA, or minimum ACT or SAT scores. If an applicant fulfills these requirements, they will likely be admitted to ASU. A student who doesnt meet minimum grade and test score requirements will still be considered through individual review, a process by which an individuals background and accomplishments are taken into consideration. Also, as a strong Division I university, Arizona State may take a students athletic skill into consideration during the admissions process. In the graph above, the blue and green dots represent accepted students. You can see that the majority of successful applicants had A or B averages in high school, and they had combined SAT scores of about 900 or higher (ERWM) and ACT composite scores of 17 or higher. Having scores and grades above that lower range significantly increases your chance of getting an acceptance letter from Arizona State. All admissions data has been sourced from the National Center for Education Statistics and Arizona State Universitys Undergraduate Admissions Office.

The United States Meat Animal Research Center - 1390 Words

Actions Speak Louder than Words Words do not have to be said for someone to be impacted. Actions send out either a positive or negative message depending upon how the action is presented. In our society, people tend to judge others by actions rather than by words. Even though there may be more behind words, actions tend to speak louder. The media features many negative stories about agriculture. One such story centered on the animal welfare occurring at the United States Meat Animal Research Center in Clay Center, Nebraska. The United States Meat Animal Research Center (USMARC) was founded 51 years ago on June 16, 1964 (U.S. Meat Animal Research Center Clay Center, NE). This research facility was established to consolidate the United States Department of Agriculture’s research on farm animals; beef, swine, and sheep in particular. The mission of the USMARC states: â€Å"Scientists at the Roman L. Hruska U.S. Meat Animal Research Center (MARC) are developing scientific information and new technology to solve high priority problems for the U.S. beef, sheep, and swine industries. Objectives are to increase efficiency of production while maintaining a lean, high quality product; therefore, the research ultimately benefits the consumer as well as the production and agri-business sectors of animal agriculture.

The Americans with Disabilities Act (ADA) A Good Start Essay

â€Å"Open your mouth for the mute, for the rights of all who are destitute. Open your mouth, judge righteously, defend the rights of the poor and needy.† (Proverbs 31:8-9). Prejudices exist in every measure, against every person, and everywhere across the world. People are inclined to judge without reason, and often hold conviction to the initial judgment made. Despite worldwide attempts to decrease these preconceptions, people must suffer through being the target on very frequent occasions.

Atlantis Free Essays

Atlantis is the subject of a legend about an advanced island civilization that was destroyed or lost. I believe Atantis is located in Bolivia based on historical evidence, advanaced architecture, advanced adimttance to road systems, and clues found in the text Critias written by the ancient Greek philospher Plato. The historical evidence in Bolivia and Atalantis match up because both civilizations were wealth, and had advanced architectual buildings. We will write a custom essay sample on Atlantis or any similar topic only for you Order Now â€Å"There is historical evidence they usesd advances architectural and agricultural techniques†¦ (http://boliviabella. com/history. html). In Critias:†Ã¢â‚¬ ¦ they had such an amount of wealth†¦ and they were furnished with everything which they needed,both in the city and country†(paragraph 14). Having a great amount of wealth means the city was ran under a ruler that controlled the city, which had advanced more then other civilizations due to the amount of control the ruler had. The wealth of Atantis and Bolivia are a factor to its architecture. Both civilizations had similar advanced architecture from the materials the building were built from. In Critias:†All the outside of the temple, with the exception of the pinnacles, they covered with silver, and the pinnacles with gold†(paragraph 16). â€Å"Modern satellite mapping shows the plain, now called the Altiplano to be of rectangular configuration, perfectly level, enclosed on all sides by mountains and these mountains contained the metals which Plato told us about, namely gold, silver, copper, tin and the mysterious Orichalcum† (an alloy of gold and copper which occurs only in the Andes) and which Plato said were used to plate the walls of the circular city. The words â€Å"Atl† and â€Å"Antis† are themselves of native America origins meaning â€Å"water† and â€Å"copper† respectively and the plain is subject to earthquakes and floods such as Plato said sank the city in a single day and night of rainfall†(http://www. atlantisbolivia. org/atlantisboliviapart1. htm). The two qoutes show that both had acces to the same materials that were used for various reasons like architecture. The civilaztion was so advanced that they had a road stystem and other things we use today like bridges. â€Å"They created a system of roads,aqueducts and hanging bridges, some of which still exist today†(http://www. oliviabella. com/history. html). In Critias:†First of all they bridged over the zones of sea which surrounded the ancient metropolis, making a road to and from the royal palace†(paragraph 15). This qoute proves that Atlantis had bridges and roads which Bolivia also had early on in their civilazation. In conclusion, I believe that Atlantis is located in Bolivia based on historical evidence, advanced architecture, and advanced admittance to road systems. Clues provided by Plato in Critias his historical account of Atlantis were also found in Bolivia, that helped me lead to the conclusion that Bolivia is where Atlantis existed.

About This Tutorial 6    Background to Worked This tutorial has been written so that users learn how to use TALPAC. The intention is that by following the series of workshops set out in this booklet, you will be able to use TALPAC, and have an appreciation as to the functionality of the program. Each of the workshops sets out a number of key TALPAC concepts, what actually needs to be completed for each workshop and what the results should be at various points. As well, there are questions that should be answered for each workshop. Some of these questions are qualitative, so no numerical answer has been provided. The phrases listed as concepts in each workshop can all be found in the on-line help. In the answers chapter of this booklet there are some answers to specific questions, and screen captures at certain points of the process which will enable you to check your progress. Often these screen captures contain the numeric answer. This tutorial does not cover every feature of TALPAC. However upon completion of this tutorial the user will have the skills required to successfully use TALPAC, and to self-learn the TALPAC facilities not covered here. Firstly it is recommended that you read through an entire workshop before starting it. TALPAC may be used to analyse the performance of existing fleets of equipment or to investigate the application of new equipment fleets in earthmoving and mining operations. In either case, the performance of a single fleet may be examined, or a comparison made of two or more different fleets. Typical TALPAC applications are listed below. Calculation of truck travel time to allow a comparative analysis of haul route alternatives. Estimation of fleet productivities for use in long and short term planning studies. Estimation and comparison of productivities using various loading methodologies to determine the optimum loading technique or loading unit bucket size. Sensitivity analysis in road design criteria to assess the relative importance of road maintenance. Calculation of tyre TKPH or TMPH ratings for use in tyre selection. Estimation of fuel usage. Determination (using discounted cash flow methods) of haulage contract costs and pricing. Truck fleet size optimisation to quantify the effect of over and under trucking. Incremental analyses, in which simulations can be automatically run for a range of haulage segment lengths and the results used to generate productivity curves. Equipment loading analysis to optimise loader bucket size, truck capacity and number of passes. Collation of results from calculations to examine the relationship between variables in the calculation, eg. haul distance versus productivity, haul distance versus truck fleet size. 6 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric 2. Background to Worked Example A contractor has been invited to submit a tender for the removal of waste from an open-cut mine, at 2. million BCM per year. The contractor utilises the following equipment: Caterpillar 992G Front End Loaders (13. 68 tonne payload); and Komatsu HD785-5 Rear Dump Trucks (99. 0 tonne payload). In bidding for the waste removal contract, the contractor must determine how many trucks and loaders are required to meet the production target and the cost of product ion. The contractor is also unsure whether to continue with the same equipment or upgrade to larger equipment. In the workshops of this tutorial we will configure the required TALPAC components so that this analysis can be undertaken.  © Runge Limited 2005 – 2008 Tutorial 7 Tutorial Metric 2. 1. Talpac Overview Key Concepts: Project, Haulage System, Template Technical Description This workshop is to generally discuss how TALPAC works and what the key areas of data input and out put are. The figure below shows how a Haulage System is made up of the unique combination of nominated templates. The templates are where the data is held for the Material, Roster, Loader, Truck and Haul Cycle. So, if you change data in one of the templates, then really you are simulating a different haulage system. In this way many Haul Systems can be stored in the one project. MATERIAL TYPES SHIFT ROSTERS HAULAGE SYSTEMS LOADER TEMPLATES TRUCK TEMPLATES HAUL CYCLES Figure 1 TALPAC Data Structure To set up a haulage system for the waste contract project, you will need to create a new haulage system, in a new TALPAC project. Initially we need to learn how to work with the templates. In later workshops we will begin entering data into these templates. 8 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric Tasks Start up TALPAC. Do this via Start gt; Programs gt; Runge Software gt; TALPAC or by double clicking on the TALPAC icon on your desktop.

The Material Type Key Concepts: Density, Swell, Fill Factor, Production Measurement Technical Description In this workshop, the characteristics of the material being hauled by the contractor will be entered into a template. The characteristics of the waste are described below. The productivity results are to be reported by volume rather than weight. Since we are working in metric units, this will mean that productivities are expressed as bcm/op. hour, bcm/shift and bcm/year. The insitu bank density is the density of the material while it is in the ground. This parameter is used to convert an insitu bank volume to its equivalent weight, and vice versa. The material swell factors are used to convert bank volumes to loose volumes in the loader bucket and the truck tray. Note that both swell factors are based on insitu volume. The loader bucket fill factor is dependent on both the material type and the class of loader. It is the ratio of the loose volume of the material in the loader bucket to the volumetric rated capacity of the loader bucket. The volumetric rated capacity of the loader bucket may be expressed on either a struck or heaped basis. Similarly, the loader bucket fill factor may be expressed on a struck or a heaped basis. The fill factor is selected from a scale in the material template. Tasks Create a new material template for the waste that the contractor is to haul. Click in the Material Template drop down box and then either right mouse click and choose Add off the menu or click on the Add button on the toolbar. Call the new template â€Å"Tutorial Waste†.

The Shift Roster Key Concepts: Roster, Delay, Scheduled, Unscheduled, Operating, Non-Operating Technical Description Working and operating hours for the loader and trucks are defined in the shift roster. The weekly shift pattern is specified, and then lost shifts per year and delays within each shift are allocated. These lost shifts and delays are divided into the following categories. Scheduled lost shifts; Unscheduled lost shifts; Non-operating shift delays; and Operating shift delays; The choice of category for a delay depends on mine site work practices. By definition, scheduled delays are those that may be fixed in time, eg. the public holiday on 25th December. Unscheduled delays are delays that you expect, but dont know exactly when they will occur, for example clean-up around the loader area and delays due to wet weather. Operating delays are those delays when the equipments engine is running. Conversely, non-operating delays are those delays when the equipments engine is not running. Tasks Set-up a roster template for the shift roster described below. Call it Tutorial Roster. The contractor operates on two shifts per day, from Monday to Friday. In addition, there is one over-time shift on Saturdays. The only rostered days of the year that are not worked are Christmas Day and Good Friday. The contractor annually allows for ten shifts lost due to industrial action and ten shifts lost as a result of wet weather. Each shift is ten hours long. The following delays occur within each shift: Crib (meal) break Delays either side of crib Delay at start of shift Delay at end of shift Delays for blasting Clean-up around loader 30 minutes 2 x 5 minutes 5 minutes 5 minutes 5 minutes 15 minutes operating operating non-operating operating non-operating operating Refuelling is carried out outside normal production hours.  © Runge Limited 2005 – 2008 Tutorial 17 Tutorial Metric Questions 1.

Selecting a Loader Key Concepts: Loader database, Distribution, Loader methodology Technical Description The contractor wants to use Caterpillar 992G front end loaders. The characteristics of the loader have been determined from historical data. We need to use this data to correctly define how the loader is to be simulated. Tasks Right click on the list of loaders and choose Add. You will now be looking at the loaders section of the equipment database. Choose Caterpillar from the Manufacturer drop down list. Scroll down through the list of loaders until you find the 992G. Click on the Select button. You will now be back in the loader template. Call this template Contract Cat 992G. The contractors 992 loaders have an expected mechanical availability of 90% and the Bucket Cycle Time takes 35 seconds. Change the Bucket Cycle Time in seconds and the minutes will calculate automatically and vice versa.  © Runge Limited 2005 – 2008 Tutorial 19 Tutorial Metric Click on the Bucket Selection button. The buckets available for the 992 are shown in the drop down list. Examine all the options available, click on the Auto Select button and see what effect it has. When you have finished click on the Restore Defaults button and then click on OK. Click on the Costing Data tab. The capital cost to the contractor of a 992G loader is $1,200,000. The contractor bases its cash flow on a 10% salvage value at the end of the loader life of 25,000 hours or 5 years (whichever occurs first). The loaders are depreciated at a rate of 15% on a straight line basis. The operating cost consists of the following components: Operating Labour Maintenance Labour Lube Tyre Replacement Wear Items Repair Parts Major Overhaul Liquid Fuels $54. 76/op. hr $19. 52/op. hr $3. 79/op. hr $11. 01/op. hr $6. 00/op. hr $45. 00/op. hr $18. 00/op. hr $25. 26/op. hr 20 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric Click on the Distribution Data tab, examine the options available but do not change anything.

A 10% salvage value at the end of the truck life of 30,000 hours or 6 years is assumed. The trucks depreciate at 25% on a straight-line basis. The operating cost consists of the following components: Operating Labour Maintenance Labour Lube Tyre Replacement Wear Items Repair Parts Major Overhaul Liquid Fuels $46. 37/op. hr $18. 24/op. hr $2. 59/op. hr $10. 91/op. hr $4. 30/op. hr $24. 08/op. hr $10. 75/op. hr $17. 24/op. hr  © Runge Limited 2005 – 2008 Tutorial 23 Tutorial Metric Click on the Distribution Data tab, examine the options available but do not change anything. Click on OK when you are finished. Set the number of trucks to Auto (not Auto-Max:1), so that TALPAC estimates the number of trucks required to keep the loader busy as follows: Estimated Fleet Size = Truck Cycle Time for Nominal Payload Truck Spot Time ? ? Nominal Truck ? ? ? Loading Time + ? at Loader ? ? Questions 1. What is the total operating cost per hour for the truck? 2. When would you use the different truck types in the same simulation? 24 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric 2. 6. Setting up a Haul Cycle Key Concepts: Segment, Rolling Resistance, Speed Restrictions, Forward and Reverse Segments Technical Description To perform a simulation, TALPAC needs data regarding the haul route. This workshop describes how this data can be converted into to a format required. The loading segments are automatically included at the start of each new haul cycle. Tasks Click on the Edit Haul Cycle button to open the Haul Cycle window. The drawing at the end of the workshop shows a typical haul profile on which the waste contract is based. Conditions to be expected in the mine are listed below: within 50 metres of the shovel and dump point, the truck speed is restricted to 30 km/hr; around corners, trucks should not exceed 30 km/hr; and when traveling down ramps, trucks must not exceed 40 km/hr. Change the name of Haul Cycle 1 to Base Haul Route. Add a new haul segment by clicking row 4 of the haul cycle and then either click on the Add button on the toolbar or by using the right mouse menu. Call the new haul segment Around Loader, the distance will be 50. 0 metres, the maximum speed is 30 km/h and all of the other factors will use the default values. The haul profile should be divided into the appropriate number of segments. The segments may be of any length, but should have a constant grade, rolling resistance and load. Dont forget to include loading, dumping and fixed time segments in the haul cycle and take into account the speed restrictions. Rolling resistance is expressed as a percentage of the component of the gross vehicle weight that is normal to the ground surface. For guidance on rolling resistance values to use, access the table from the rolling resistance column, right mouse click on one of the cells in the Rolling Resistance column and choose Select. We will be using the average conditions for this tutorial, so click in the average column of the row in the table that best describes the current haul segment.  © Runge Limited 2005 – 2008 Tutorial 25 Tutorial Metric When you have added all of the haul segments needed, add the dumping segments. As the haul route for the return journey is the same it is possible to use the Reverse all segments option. Reverse all of the segments. 26 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric Questions 1. When is a new segment required? 2. How many segments are required? 3.

Production Analysis Key Concepts: Calculation Type, Full Simulation, Stochastic, Excavation Target Technical Description Once the haulage system has been defined it is ready to be analysed. In asse ssing the productive capacity of the system you have the choice of using the quick estimate or the full simulation. The other types of calculations will be discussed later. Quick estimate assumes there is no variability in the truck and loader parameters, and a deterministic analysis is performed. Full simulation takes the variability of truck and loader parameters into account using a stochastic analysis. Parameters that may be varied in the full simulation include loader bucket cycle time, loader bucket payload, truck travel time, truck dumping time and truck availability. The Excavation Target feature allows the user to specify a production target. When an excavation target is specified the Production Summary Report lists how many days/years that it would take to move the specified excavation target. The value for the target is independent on the measurement basis chosen in the material template. Tasks Clicking on the Type of Calculation list box may access Quick Estimate. Select Quick Estimate and either press the F9 key or click on the Calculate button. Similarly, selecting Full Simulation from the Type of Calculation list box and by using the F10 key or to click on the Calculate Results button to access Full Simulation. View the simulation results for each option and compare the differences. View the haul cycle details, the tyres and fuel consumption, and the cash flow screens. View the defined travel time graphs to identify the key segments of the haul cycle. Enter a Excavation Target of 2,500,000 bcm, run a Full Simulation and then view the results at the bottom of the Production Summary Report. Questions 1. Why is it useful to have different calculation types? 2. What is the vertical height difference that the load is being elevated through? 3. Why can you get different results for successive runs? 4. How long does it take to reach the production target? 28 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric 2. 8. Incremental Analysis and Results Tables Key Concepts: Incremental Analysis, Results Tables Technical Description The haul profile used so far is representative of haul routes at the mid-life of the waste contract. In the early years the pit is shallower and in the later years it is deeper. The change in RL and the length of the ramp out of the pit vary as follows: Year 1 2 3 4 5 Length of Pit Ramp 200 metres 300 metres 400 metres 500 metres 600 metres The distance and elevation from the surface to the top of the waste dump do not change. In planning we need to understand how the productivity requirements change for the life of the contract. Also we are interested in seeing the results tabulated in a different format to the standard results. Tasks Based on this information, determine the productivity of the fleet for each year of the contract. Choose the Incremental Analysis button. In the Incremental Analysis window choose the Add button. In the Incremental Item Selection window choose Haul Segment Distance from the Item dropdown list. Choose Pit Ramp segment from the Forward Segment dropdown list. Choose 15: Pit Ramp (rev. ) from the Reverse Segment dropdown list. Set the First Value to 200 metres, the Last Value to 600 metres and the Step Value to 100 metres. Click on OK.  © Runge Limited 2005 – 2008 Tutorial 29 Tutorial Metric If the Incremental Analysis window looks like this, then click on Calculate. 30 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric Examine the information displayed in the Results Table.

Fleet Size Optimisation Key Concepts: Optimisation Analaysis, Marginal Economics Technical Description The optimum number of trucks in a fleet is a balance between productivity and cost. The fleet size optimisation carries out a series of production analyses for a range of truck fleet sizes. The results are summarised in a table displaying the fleet size, the fleet production and the discounted average cost. The results can also be displayed on a graph. The optimum fleet size is that with the lowest unit cost of production. The optimum fleet size will not necessarily have the highest production or provide the required output. Tasks Create a copy of the Base Waste Contract haulage, hit the F2 key and rename it Workshop Fleet Size. Make a copy of the base haul cycle, and call it Workshop Haul. In Workshop Haul, change the pit ramp distance to 2,000 m. Remember to change both the forward and reverse segments of the pit ramp. Configure the rest of this haul system to have the same loader, truck, material and roster templates. Make sure you save this haul system after you have selected the appropriate items. Do a Full Simulation and note the number of trucks. Now determine the optimum number of trucks for the contractors fleet. Choose the Optimisation button. Choose the Fleet Size radio button and then click on OK. Plot a graph of the Fleet size versus the marginal cost. Compare the optimum with the truck match determined in the full simulation in the previously in this workshop. 34 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric Export the Results Table by going to File gt; Export, click on the Browse button and choose a name and location for the file. Make sure the Excel File (. XLS) radio button is chosen and then click on OK. Open up your results file in Excel and examine the data. Questions 1. What is the marginal cost of assigning one more truck than the optimum? 2. Why are the marginal economics important, and not just the average cost? 3. What is the optimum fleet size?  © Runge Limited 2005 – 2008 Tutorial 35 Tutorial Metric 2. 10. Key Concepts: Fleet Comparison Haulage Systems Technical Description The contractor wishes to investigate the cost benefits of moving to larger equipment for the waste removal contract. A new haulage system is going to be configured for the larger equipment. New truck and loader templates will be created. Tasks Add a new Haulage System, called Workshop Comparison. This will have the Tutorial roster, the tutorial waste, and the Base Haul Route from the Basic Waste Contract haulage system. Create a new template for both the truck and loader, the details of the larger equipment items in which the contractor is interested are as follows: Item Name Type Capacity Availability Capital Salvage Value Life in Years Life in Hours Depreciation type Depreciation Rate Total Operating Cost Shovel Komatsu-Demag H 285 S Hydraulic Shovel 16. cu. m heaped 90% $2,000,000 10% 8 35000 Straight line 15% $222. 73 Truck Dresser 510E Rear Dump Trucks 136. 14 tonne payload 85% $1,300,000 10% 8 35000 Straight line 25% $163. 50 With this equipment each bucket cycle takes 30 seconds. Also for the trucks the spot time at the loader is 30 seconds. The spot time at dump is 30 seconds and the dump t ime is 30 seconds. Use the Total Operating Cost checkbox to enter the operating cost 36 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric Compare the discounted average cost for the equipment fleet above with the equipment fleet used in the previous workshop. In determining the discounted average cost, use the optimum truck fleet size for each option. Questions 1. Which equipment fleet would you recommend the contractor purchase? 2. What factors affect this decision?  © Runge Limited 2005 – 2008 Tutorial 37 Tutorial Metric 2. 11. Key Concepts: The Equipment Database User Defined Equipment Technical Description The equipment database contains a large range of trucks and loaders used in surface mining operations. The data supplied in the equipment database represents standard equipment and has been verified by the appropriate manufacturer. For equipment that is not in the database or that has been modified, the user is able to set-up their own equipment items. Tasks Access the equipment database from either View gt; Equipment Database or the Equipment Database button on the toolbar. Use the Type, Manufacturer and Class drop down lists to view a truck and a loader to see the data that is stored in the database for each equipment type. Create a user defined equipment item by copying a standard item of equipment to a new name. To copy an item from the standard database to a user database go to Edit gt; Copy Equipment. Rename your copy of the Komatsu HD785-5 to My Mines 785-5. Question 1. What role would User Defined equipment have at your operation? 38 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric 2. 12. Key Concepts: Importing a Haul Cycle Importing a Haul Cycle from a Text File Technical Description In a previous workshop we have created a haul cycle by manually typing in the required details for each segment. In TALPAC you can also import this data directly from a text file. In turn this text file can be automatically generated in another system, such as a design package or a fleet monitoring / dispatch system. The text file import facility in TALPAC can be quite sophisticated, and in this workshop only a small portion of the functionality will be used. For more advanced requirements please refer to the help documentation, or contact Runge. Tasks In the Talpac \Tutorials directory there is a flat text file called â€Å"Test XYZ Space. txt†. Open this file with a text editor and inspect the layout. This file represents the co-ordinates of a haul route. Close the file after inspection. In TALPAC add a new Haul System called â€Å"Workshop Import†. Go to File gt; Import Haul Cycles from a Text File. Click on the Add button and create a new template called Tutorial. Click on the Browse button and find the file Test XYZ Space. txt. Select Space as the Field Delimiter Characters. Leave the First Import Line as 1, and also leave the Comment Character as ! Now click twice on the Next Line button, so that line 3 of the file is shown in the viewer. Set the Import Data Type radio button to X,Y,Z co-ordinates. Enter appropriate field numbers for the entities. That is: X coord Y coord Z coord 2 3 4. All other fields should have a 0 value. This means that you will be accepting the defaults shown for those fields. When complete, select the Reverse all segments setting load to â€Å"Empty† check box, and then click on OK.  © Runge Limited 2005 – 2008 Tutorial 39 Tutorial Metric Inspect the results in TALPAC. Check that the haul cycle Import Test Haul 1 has been imported. Questions 1. Why is the new haul cycle called â€Å"Import Test Haul 1†? 2. How can this feature be used in your situation? 3. How else can the import facility be used? 40 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric 2. 13. Key Concepts: Talpac Options Project Options, Customising TALPAC, Project Management, Feedback, Project Properties Technical Description There are many variables and Options used in TALPAC that are not contained within any of the templates that we have looked at so far.

Questions 1. When should you change the options settings? . How can you tell the location of the current user database? 3. How can the project manager interact with mine planning?  © Runge Limited 2005 – 2008 Tutorial 41 Tutorial Metric 2. 14. Calibrating Talpac 2. 14. 1. Why Calibrate? Talpac is a proven tool for conducting Haul Simulation using the numerous input parameters that impact Truck and Loader fleet performance. Variations in material characteristics, operating conditions, equipment modifications and mine operating procedures can all have an impact on fleet performance. Calibrating Talpac to match actual productivities ensures that the results from the simulations reflect the individual conditions of your operating environment, allowing you to calculate and report with confidence in the results. How to Calibrate 1. Open your Project in Talpac and verify that the correct Haul Cycle, Loading Unit and Truck Types are selected. 2. Click on the All Parameters button in the Talpac Data Entry screen and print out the list of parameters. This print-out lists all of the data being used in your Talpac project whether default values or data that you have entered. . Gather performance data from your mine site for the key parameters. Possible sources of data include: Truck and Loader on-board performance monitors Mine fleet dispatch and monitoring systems Manufacturer supplied specifications for the equipment at your site Pit and dump plans showing elevations along the haul route Time and Motion field studies Production records e. g. truck counts, belt weighto meters, surveyed volumes. 4. Run some test simulations and compare the results to real-world performance data from your site. Ideally the performance data will be for a whole shift for a particular haulage system (otherwise a few repetitive timings of a particular haulage system can be used). Adjust the model as necessary to ensure that the Talpac results are in line with actual performance data. Some of the common adjustments that you might make are: User Equipment If equipment specifications are significantly different to the data in the Talpac database, create User Equipment in Talpac with the actual specifications and performance curves. Truck Travel Time Compare measured travel times segment by segment with those in the Haul Cycle Report Vary the rolling resistances in the Haul Cycle Vary the Travel Time Correction Factor Truck Cycle Time Set calculation mode to Quick Estimate (rather than Full Simulation) to eliminate variability in parameters during calibration Check Truck queuing and loading time (and number of Trucks) Check Truck spotting time and First Bucket Pass Delay 42 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric Truck Productivity Vary the non-operating shift delays and operating shift delays (Roster Template) to achieve the actual working hours Set Truck Availability to 100% for the calibration exercise Loader Productivity Ensure that the Number of Passes to Fill Truck reflect actual data 5. Re-calibrate at frequent intervals. Points to consider Here are a few points to consider when gathering the calibration data for your site: Material Characteristics What is the In Situ Bulk Density and how is it measured? What swell factors are included in the data In Situ into the Bucket; In Situ into the Truck? How well does the Loader dig? What is the Bucket Fill Factor? Seasonal variations in Material characteristics (e. g. Wet Weather, Snow) Is there carryback of sticky material in the empty Trucks? Working Roster What are the site values for Hours/Shifts/Day for each day of the week? What are the site values for lost days per year (e. g. Weather, Industrial, Public Holidays)? Are there Delays that do not occur every shift (e. g. Blasting, equipment relocation, power outages)? What is the average operating time per shift (operator in the equipment, equipment in operating condition)? What are the average operating delays per shift (e. g. Loader waiting for dozer clean-up, moving large rocks)? Equipment Physicals What equipment models are being used on the calibration haul? Do they differ from the Manufacturers Handbook Specifications, and if so, what are the revised specifications (and the performance curves, if relevant)? Note: Changing tyre size or engine power or gear ratio requires a revised set of truck performance curves. Was all equipment purchased at the same time (differences in Operating life will result in variations in performance)? Has the equipment been maintained in accordance with the Manufacturers recommended Maintenance Schedule (poorly maintained Trucks may not perform in accordance with the Manufacturers performance curves)?  © Runge Limited 2005 – 2008 Tutorial 43 Tutorial Metric Haul Route What are the segment distances and grades? What operating conditions may affect equipment performance? Do seasonal variations affect the Haul Route and Truck performance (e. g. Wet Weather, Fog, Snow, Dust Storms)? What speed restrictions apply (e. g. for safety, tyre heating management)? What is the productivity of the Truck drivers? Real World Performance Data Truck Actual Haul Profile and Speed Limits Best estimate of rolling resistance for each haul segment Actual number of Trucks assigned to the Loader Actual Truck travel times (empty loaded) for each segment of the actual profile, including Truck loading, spotting, dumping and queuing times Actual Truck payload and empty Truck weight Loader Loading regime (single sided or double sided) Actual number of Loader passes to fill Truck Actual time waiting for Trucks First pass bucket delay Fleet Actual number of working hours per shift Actual probability distributions for Truck travel time, Truck dumping time, Truck availability, bucket payload and bucket cycle time Representative Real World Performance Data Fleet performance on a particular haulage system can vary over time due to several factors, including: weather conditions diggability at the loader face (blast performance) haul road conditions Truck driver performance Loader operator performance condition of the equipment traffic density (night shift versus day shift) the number of Trucks assigned to the Loader. Most users build one Talpac model for their site, so real world performance data (for calibrating Talpac) is ideally representative of the long term averages of the variables mentioned above. 44 Tutorial  © Runge Limited 2005 – 2008 Tutorial Metric  © Runge Limited 2005 – 2008 Tutorial 45 Tutorial Metric 3.

What is the key information? Key Information is what you need to see, and so depends on the purpose of the simulation. In this instance, cost, time, productivity, fleet size and length of haul would be key. 2. How many variables are available for inclusion in the results table? 250. 3. When should you consider purchasing another truck? In year 3. But what else should be considered? Runge Limited 2005 – 2008 Answers 53 Tutorial Metric WORKSHOP 9: FLEET SIZE OPTIMIZATION 1. What is the marginal cost of assigning one more truck than the optimum? $2. 97 / bcm. 2. Why are the marginal economics important, and not just the average cost? Average costs disguise the impact of individ ual truck assignment. 3. What is the optimum fleet size? The run with the lowest fleet discount cost. 54 Answers  © Runge Limited 2005 – 2008 Tutorial Metric WORKSHOP 10: FLEET COMPARISON 1. Which equipment fleet would you recommend the contractor purchase? The larger fleet is the pure cost choice, but is this correct? 2. What factors affect this decision? Cost of capital, changes to working hours, flexibility of contract.  © Runge Limited 2005 – 2008 Answers 55 Tutorial Metric WORKSHOP 11: THE EQUIPMENT DATABASE 1. What role would User Defined equipment have at your operation? You can set up the specifications for the Truck and Loader which exactly match your configuration, rather than relying on the standard data. 56 Answers  © Runge Limited 2005 – 2008 Tutorial Metric WORKSHOP 12: IMPORTING A HAUL CYCLE 1. Why is the new haul cycle called â€Å"Import Test Haul 1†? Set by the variable on line 2 of the import file. Otherwise it will be imported and called the same as the import file name. 2. How can this feature be used in your situation? Eg From the mine design package a string can be digitised which represents the haul route. This string can then be exported to a text file as a series of X,Y, Z points. From there it can be imported directly into TALPAC. 3. How else can the import facility be used? To import complete Haul Systems.  © Runge Limited 2005 – 2008 Answers 57 Tutorial Metric WORKSHOP 13: TALPAC OPTIONS 1. When should you change the options settings? Only after consideration of what they are doing. It is also suggested that if these are changed, then make sure that changes are properly recorded. The ALL PARAMETERS print outs, and user defined reports in the Results Tables are two good ways of doing this. 2. How can the project manager interact with mine planning? Can make the analysis of multiple simulations easier and more straight forward. 3. How can you tell the location of the current user database? Under View gt; Project Properties the location and name of the current user database is shown. 58 Answers  © Runge Limited 2005 – 2008 Tutorial Metric 4. Talpac Commands 4. 1.
