Alternative A may be considered if the investor is very short of cash and the short payback period is of importance to him. The Present Worth method requires common analysis period, which is virtually impossible for this problem. The problem is easy to solve by Annual Cash Flow Analysis. In future worth analysis there must be a common future time for all calculations. In this case 12 years hence is a practical future time. C Alt. Increment B- C Year Alt. B Alt. lternative nalysis of the Increment B- C An examination of the B- C cash flow suggests there is an external investment of money at the end of Year 4.

Solutions for part b : Choose Alternative C. d Payback period is the time required to recover the investment. Thus each generates uniform annual benefits in excess of the cost, during the life of the alternative. From this is must follow that the alternative with a 2-year life has a payback period less than 2 years. The alternative with a 4-year life has a payback period less than 4 years, and the alternative with a 6-year life has a payback period less than 6 years. Thus we see that the shorter-lived asset automatically has an advantage over longer-lived alternatives in a situation like this. While Alternative A takes the shortest amount of time to recover its investment, Alternative C is best for long- term economic efficiency.

c No computations are needed. The problem may be solved by inspection. Alternative z dominates Alternative y. Alternative z has a positive rate of return actually Choose Alternative z. To maximize NFW, select F. To minimize payback period, select F. Here, however, we will include it. c Both a and b are ´correct. Chapter Uncertainty in Future Events a Some reasons why a pole might be removed from useful service: 1. The pole has deteriorated and can no longer perform its function of safely supporting the telephone lines 2. The telephone lines are removed from the pole and put underground. The poles, no longer being needed, are removed. Poles are destroyed by damage from fire, automobiles, etc. The street is widened and the pole no longer is in a suitable street location. The pole is where someone wants to construct a driveway. b Telephone poles face varying weather and soil conditions; hence there may be large variations in their useful lives. Typical values for Pacific Telephone Co. in California are: Optimistic Life: 59 years Most Likely Life: 28 years Pessimistic Life: 2.

The salvage value drops by 5x8,x. The salvage value increases by 5x8,x. So the total probability of higher rates for year 2 is. An inspection of the Regular Season situation reveals that the sum of the probabilities for the outcomes enumerated is 0. Thus one outcome win less than three games , with probability 0. This is not a faulty problem statement. The student is expected to observe this difficulty. Die 1 Die 2 2 6 3 5 4 4 5 3 6 2 The five ways of throwing an 8 have equal probability of 0. The probability of winning is 0. Here it is ignored. Remember, only the differences between alternatives are relevant.

The occurrence of a year flood this year is no guarantee that it won¶t happen again next year. In any year period, for example, there are 4 chances in 10 that a year flood or greater will occur. Using a probabilistic approach, however, Alternative I is most likely to result in the least equivalent uniform annual cost. State Bad OK Great Probability. This also equals the E PW of the avoided negative net revenue in years 2 ± 5, which equals. The P loss is unchanged at. For example, the first and second rows' PWs are unchanged. The probability of a negative PW is. This illustrates why standard deviation alone is not the best measure of risk.

The standard deviation is higher, but the P loss has dropped by half. a catastrophic loss is an unacceptable risk or 2. he has a loan on the home and fire insurance is required by the lender. useful life at begin. of yr. One can also see this by inspection of the depreciation schedules above. Cost of Proceeds Undep. capital acq. of capital undep. rate cost Capital cost at during the disp. This is not a correct analysis of the situation. This may be illustrated by computing the Straight Line depreciation for Year 3, if DDB depreciation had been used in the prior years.

While the depreciation charges in any year may be different for different methods, the sum of the depreciation charges will be the same. The difference is not the amount of the taxes, but their timing.

XYZ, Inc. Further calculations show actual rate of return to be approximately 4. It does change the timing of these items. Calculator solution is Therefore the project should not be undertaken. The cash investment is greatly reduced. Since the truck rate of return Two items worth noting: 1. The truck and the loan are independent decisions and probably should be examined separately. There is increased risk when investments are leveraged. c Based on the rate of return of 9. Choose Alternative 1. d To maximize Net Future Worth, choose Alternative 1. Choose B. By NPW one can see that A is the better of the two undesirable alternatives. Select Alternative A.

Chapter eplacement nalysis For the Replacement Analysis Decision Map, the appropriate analysis method is a function of the cash flows and assumptions made regarding the defender and challenger assets. Thus, the answer would be the last it depends on the data and the assumptions The replacement decision is a function of both the defender and the challenger. The statement is false. This is such a common situation that the early versions of the MAPI replacement analysis model were based on a one year remaining life for the defender. The answer is one year. The EUAC of maintenance is constant. Thus total EUAC is declining over time. Answer: For minimum EUAC, keep the bottling machine indefinitely. The book indicates that trade-in value may be purposely inflated as a selling strategy, hence it may or may not represent market value.

Retraining in operation and maintenance may be required. High comfort of operation. High purchase price. May not be immediately available. Sales taxes to be paid. Can be depreciated. Supplier warranty and spare parts backup available. b All as in a except for lower price and probably faster delivery. c All as in a except for still lower cost, lost production during the rebuild period, and that the rebuild costs can be expensed, at least partially. No sales tax applies. d Performance and productivity may not be as good as in option c. Retraining in operation and maintenance is not required. Production will be lost during the rebuilding period. Cost may be substantially lower than in previous options. The rebuild costs can be expensed. e Performance, productivity, service life, energy efficiency, safety, reliability may be significantly lower than in the other options. Retraining in operation and maintenance may be required if the new unit is different from the previous one.

Immediate delivery is a possibility. The sales tax applies. Equipment can be depreciated. This would lead to the use of Replacement Analysis Technique 2. In this case we compute the minimum cost life of the defender and compare the EUAC at that life against the EUAC of the best available challenger. We chose the options with the smallest EUAC. If the challenger is superior, then the defender tank probably will be replaced. It will cost a substantial amount of money to remove the existing tank from the plant, sell it to someone else, and then buy and install another one. As a practical matter, it seems unlikely that this will be economical. The best useful life will be the one in which EUAC is a minimum. Year Reconditioned New New vs. The Thus we use Replacement Analysis Technique 1 and compare the marginal cost data of the defender against the min.

EUAC of the challenger. Let¶s find the Challenger¶s min. EUAC at its 5-year life. Challenger Challenger¶s min. cost life is given at 5 years in the problem. This is because after three years the marginal costs of the Defender become greater than the min. EUAC of the Challenger. Thus, we use Replacement Analysis Technique 1 and compare the marginal cost data of the defender against the min. From the previous problem the Challenger¶s min. Lost Lost MV Total Line Interest Marg. b In looking at the table above one can see that the marginal cost data of the defender is strictly increasing over the next five year period.

Thus the Replacement Decision Analysis Map would suggest that we use Replacement Analysis Technique 1. We compare the defender marginal cost data against the challenger¶s minimum EUAC. We would keep the defender asset for two more years and then replace it with the new automated shearing equipment. From Figure the marginal cost data is available, and it is not strictly increasing see Total MC column in the table below. Thus, we use eplacement nalysis Technique 2, comparing minimum EU C defender against minimum EU C of challenger. Thus, we recommend keeping the defender for at least one more year and reviewing the data for changes. c Using Replacement Analysis Technique 3: Assuming that the defender and challenger costs do not change over the next 4 years we should keep the defender for four years and then reevaluate the costs with challengers at that time. Here we are comparing the min.

EUAC def vs. c Using Replacement Analysis Technique 3: èiven these costs for the defender and challenger we should replace the defender with the challenger asset now. This is because the min. Because the remaining life of the defender and the life of the challenger are both 10 years we can use either the ³opportunity cost´ or ³cash flow´ approach to setting the first cost of each option keep defender or replace with challenger. The problem says the challenger economic life is 10 years. Using the data provided this fact could be verified, but that is not part of the problem. Annual Cash-Flow Analysis: Keep Old Forklift nother Year Year BTCF Deprec. Keep the old forklift another year. A first step is to compute an after-tax cash flow for each alternative.

In this way the currency itself is less valuable on a per unit basis. These are the dollars that we carry around in our wallets and purses, and have in our savings accounts.

Real dollars represent dollars that do not carry with them the effects of inflation, these are sometimes called ³inflation free´ dollars. Real dollars are expressed as of purchasing power base, such as Yearbased-dollars. The inflation rate captures the loss in purchasing power of money in a percentage rate form. The real interest rate captures the growth of purchasing power, it does not include the effects of inflation is sometimes called the ³inflation free´ interest rate. The market interest rate, also called the combined rate, combines the inflation and real rates into a single rate. Dollars, and interest rates, are used in engineering economic analyses to evaluate projects. As such, the purchasing power of dollars, and the effects of inflation on interest rates, are important. The important principle in considering effects of inflation is not to mix-and-match dollars and interest rates that include, or do not include, the effect of inflation.

A constant dollar analysis uses real dollars and a real interest rate, a then-current or actual dollar analysis uses actual dollars and a market interest rate. In much of this book actual dollars cash flows are used along with a market interest rate to evaluate projects this is an example of the later type of analysis. The goods included in this index are those commonly purchased by consumers in the US economy e. food, clothing, entertainment, housing, etc. Composite indexes measure a collection of items that are related.

The CPI and Producers Price Index PPI are examples of composite indexes. The PPI measures the cost to produce goods and services by companies in our economy items in the PPI include materials, wages, overhead, etc. Commodity specific indexes track the costs of specific and individual items, such as a labor cost index, a material cost index, a ³football ticket´ index, etc. Both commodity specific and composite indexes can be used in engineering economic analyses. Their use depends on how the index is being used to measure or predict cash flows. If, in the analysis, we are interested in estimating the labor costs of a new production process, we would use a specific labor cost commodity index to develop the estimate. Much along the same lines, if we wanted to know the cost of treated lumber 5 years from today, we might use a commodity index that tracks costs of treated lumber.

Allowable depreciation charges are based on the original equipment cost and do not increase. Thus the stable price assumption may be suitable in some before-tax computations, but is not satisfactory where depreciation affects the income tax computations. So purchase pads of paper- one for immediate use plus 4 extra pads. But will one have ³profited´ from the inflation? Whether one will profit from owning the house depends somewhat on an examination of the alternate use of the money. Only the differences between alternatives are relevant.

If ³profit´ means an enrichment, or being better off, then multiplying the price of everything does no enrich one in real terms. Find i'. This problem illustrates the fact that the prospect of future inflation encourages current expenditures to be able to avoid higher future expenditures. This is the year of which the index has a value of Current Future Car Price Inflation Price X 4. One simple rule might involve using the average of the last 5 years inflation rates. This rate would be 1. If the money available from depreciation charges is inadequate to purchase needed replacement equipment, then the firm may need also to use after-tax profit for this purpose.

Depreciation charges produce a tax-free source of money; profit has been subjected to income taxes. Thus substantial inflation forces a firm to increasingly finance replacement equipment out of costly after-tax profit. Stated in Year 0 dollars, the total receipts are less than the cost, hence there is no positive rate of return. Choose the higher cost alternative: choose Alternative A. Chapter Selection of a Minimum ttractive ate of eturn The interest rates on these securities vary greatly over time, making it impossible to predict rates. Three factors that distinguish the securities: Bond Duration Bond Safety Municipal Bond 20 years Safe Corporate Bond 20 years Less Safe The importance of the non-taxable income feature usually makes the municipal bond the one with the lowest interest rate.

The corporate bond generally will have the highest interest rate. C is preferred for 4. Leasing is therefore preferred at all interest rates above b Items that might make leasing more desirable: 1. One can make more than One does not have to be concerned about the resale value of the car at the end of two years. Deposit of the money in a Bank. Purchase of common stock, US Treasury bonds, or corporate bonds. Investment in a new business, or an existing business. and so on. The process of identifying and selecting investments is a time-consuming and hence costly process.

Some might argue the b Yes. social consequences are more important than the economics. Probably there are a variety of considerations much more important than c? the economics. Picking a career on an economic basis sounds terrible. Picking a wife on an economic basis sounds even worse.

It would take over a year at 0. The chocolate bar problem is suitable for economic analysis. Compared to the investment problem it is, of course, trivial. Joe¶s problem is a real problem with serious economic consequences. The difficulty may be in figuring out what one gains if he pays for the fender damage, instead of having the insurance company pay for it. For the three machinists it represents a major event with major consequences. Nevertheless, it is still a complex problem. The maximum number of pads might be the quantity needed over a reasonable period of time, like the rest of the academic year.

None of the situations represents rational decision-making. Choosing the same career as a friend might be OK, but it doesn¶t seem too rational. Jill didn¶t consider all the alternatives. Don thought he was minimizing cost, but it didn¶t work. Maybe rational decision-making says one should buy better tools that will last. President Kennedy used the latter approach with a year for landing a man on the moon to inspire employees. Thus the following objectives as examples are concrete. No year is specified here, because unlike President Kennedy we do not know what dates may be achievable. Choosing among these objectives involves technical decisions some objectives may be prerequisites for others , political decisions balance between science and applied knowledge for man¶s activities , and economic decisions how many dollars per year can be allocated to NASA.

However, our favorite is a colony on the moon, because a colony is intended to be permanent and it would represent a new frontier for human ingenuity and opportunity. Evaluation of alternatives would focus on costs, uncertainties, and schedules. Estimates of these would rely on NASA¶s historical experience, expert judgment, and some of the estimating tools discussed in Chapter 2. One approach might be: a Find out what percentage of the population is left-handed. b What is the population of the selected hometown? c Next, market research might be required. With some specific scissors quality and price in mind, ask a random sample of people if they would purchase the scissors. Study the responses of both left-handed and right-handed people. d With only two hours available, this is probably all the information one could collect.

From the data, make an estimate. A different approach might be to assume that the people interested in left handed scissors in the future will be about the same as the number who bought them in the past. a Telephone several sewing and department stores in the area. Ask two questions: i How many pairs of scissors have you sold in one year or six months or? ii What is the ratio of sales of left-handed scissors to regular scissor? b From the data in a , estimate the future demand for left-handed scissors. Two items might be worth noting. Lots of scissors are universal, and equally useful for left- and right-handed people. Many left-handed people probably never have heard of left-handed scissors. Live at home. A room in a private home in return for work in the garden, etc. Become a Resident Assistant in a University dormitory.

Live in a camper-or tent- in a nearby rural area. Live in a trailer on a construction site in return for µkeeping an eye on the place. This may lead to an acceptable or even a good choice, but it is highly unlikely to lead to the best choice. While reading about models, the car buyer can be identifying alternatives and clarifying which features are important. With this in mind, several car lots can be visited to see many of the choices. Then either a dealer or the classifieds can be used to select the best alternative. b Minimize input. c Maximize the difference between output and input. d Minimize input. b Maximize the difference between output and input. c Minimize input. There are benefits to those who gain from the decision, but no one is harmed. Pareto Optimum 2. Benefits flow to those who need them most. Minimize air pollution or other specific item. Maximize total employment on the project. Maximize pay and benefits for some group e.

Most aesthetically pleasing result. Fit into normal workweek to avoid overtime. Maximize the use of the people already within the company. Unfortunately, people who are relocated often feel harmed, no matter how much money, etc. Thus planners consider criterion a unworkable and use criterion b instead. In some cases, these projects are also used for urban renewal of decayed residential or industrial areas, which introduces other benefits. The costs of these projects include the money spent on the project, the time lost by travelers due to construction caused congestion, and the lost residences and businesses of those displaced. In some cases, the loss may be intangible as a road separates a neighborhood into two pieces. In other cases, the loss may be due to living next to a source of air, noise, and visual pollution. Jay appears to prefer Alternative 2, and he has sufficient money to adopt it. While there are alternatives available, one appears so obvious that that foreman discarded the rest and asks to proceed with the replacement.

One could argue that the foreman, or the plant manager, or both are making decisions. There is no single µright¶ answer to this problem. Although suggested by the clerk, it was Bill¶s decision. One of my students observed that his father would not fall for such a simple deception, and surely would insist on the weird shirt as a subtle form of punishment. Alternatives to their current university program are likely to focus on other fields of engineering and science, but answers are likely to be distributed over most fields offered by the university.
