Solve a Q5-) A regional infrastructure building and maintenance contractor must decide to buy a new compact horizontaldirectional drilling (HDD) machine now, or wait and buy it 2 years from now when a large pipeline contract willrequire the new equipment. The HDD machine will include an innovative pipe loader design and a maneuverableundercarriage system. The cost of the system is $68,000 if purchased now or an estimated $81,000 if purchased2 years from now. At i = 10% per year and f= 5% per year, determine if the contractor should buy now or later(a) without any adjustment for inflation, and (b) with inflation considered.

HDD (Horizontal Directional Drilling) is a trench less method of constructing underground pipes,…

2) - AMT, Inc., is considering the purchase of a digital camera for maintenance of design specifications by feeding digital pictures directly into an engineering workstation where computer-aided design files can be superimposed over the digital pictures. Differences between the two images can be noted, and corrections, as appropriate, can then be made by design engineers. a) You have been asked by management to determine the PW of the EVA of this equipment, assuming the following estimates: capital investment = $345,000; market value at end of year six = $120,000; annual revenues = $120,000; annual expenses = $8,000; equipment life = 6 years; effective income tax rate = 50%; and after-tax MARR = 9% per year. MACRS depreciation will be used with a five-year recovery period. b) Compute the PW of the equipment's ATCFS. Is your answer in Part (a) the same as your answer in Part (b)?
1. Decision Rules. A company is choosing a motorized mechanism for a new toy, a dancing ballerina (TippiToes) that is currently under development. Demand is uncertain. but the company is confident that demand will be: Light (25,000 units), Moderate (100,000 units) or Heavy (150,000) units. The payoff table for each mechanism (in $) is given below. Action: Choice of Mechanism Event Gears and Levers Spring Weights and Pulleys Pneumatic Light 25,000 -10,000 -125,000 -300,000 Moderate 400,000 440,000 400,000 300,000 Heavy 650,000 740,000 750,000 700,000 Questions: (1) Apply Maximax, Maximin, Minimax Regret, and EMV rules (assuming that the probability of Light demand is 0.1, Moderate demand is 0.7, and Heavy demand is 0.2) to decide what mechanism should the company choose? (2) What is the expected value of perfect information? (3) Draw a decision tree to solve this problem.

Wind Tunnel Testing – Carbon Bike Frames As an equipment provider for several Olympic cyclists, Carbon Bike Frames (CBF) operates a very expensive wind tunnel facility near San Diego, CA. The wind tunnel is used to find the best compromise between ergonomics and aerodynamics for the cyclist. Presently, more and more cyclists are interested in CBF’s services, so the company considers building a second facility. However, given the enormous costs of the wind tunnel, they also want to explore a more effective use of the current facility. An initial data collection reveals that: The standard fitting time for a cyclist is 2h. On average, the wind tunnel is used for 7 fitting procedures a day (new customers or customers who want a refit). The wind tunnel is available 24 hours a day. CBF offers a free second session should the customer not be entirely satisfied with their bike fit (internally also known as “rework sessions”). About 2 out of 5 customers come back for such a “refit,” which…

Merrimac Manufacturing Company has always purchased acertain component part from a supplier on the East Coast for$50 per part. The supplier is reliable and has maintained thesame price structure for years. Recently, improvements in operations and reduced product demand have cleared up somecapacity in Merrimac’s own plant for producing componentparts. The particular part in question could be produced at$40 per part, with an annual fixed investment of $25,000.Currently, Merrimac needs 300 of these parts per year.a. Should Merrimac make or buy the component part?b. As another alternative, a new supplier located nearby isoffering volume discounts for new customers of $50per part for the first 100 parts ordered and $45 per partfor each additional unit ordered. Should Merrimacmake the component in-house, buy it from the newsupplier, or stick with the old supplier?c. Would your decision change if Merrimac’s annual demand increased to 2000 parts? increased to 5000 parts?d. Develop a set of…
Case Study: Montana Mountain Biking Jerry Singleton founded Montana Mountain Biking (MMB) 18 years ago. MMB offers one-week guided mountain biking expeditions based in four Montana locations. Most of MMB’s new customers hear about the company and its tours from existing customers. Many of MMB’s customers come back every year for a mountain biking expedition; about 80 percent of the riders on any given expedition are repeat customers.Jerry is happy with this high repeat percentage, but he is worried that MMB is missing a large potential market. He has been reluctant to spend a lot of money on advertising. About 10 yearsago, he spent $80,000 on a print advertising campaign that included ads in several outdoor interest and sports magazines, but the ads did not generate enough additional customers to cover the cost of the advertising. Five years ago, a marketing consultant advised Jerry that the ads had not been placed well. The magazines did not reach the serious mountain bike enthusiast,…

Problem 1. During your first month as an employee at Greenfield Industries (a large drill- bit manufacturer), you are asked to evaluate alternatives for producing a newly designed drill bit on a turning machine. Your boss' memorandum to you has practically no information about what the alternatives are and what criteria should be used. The same task was posed to a previous employee who could not finish the analysis, but she has given you the following information: An old turning machine valued at $350,000 exists (in the warehouse) that can be modified for the new drill bit. The in-house technicians have given an estimate of $40,000 to modify this machine, and they assure you that they will have the machine ready before the projected start date (although they have never done any modifications of this type). It is hoped that the old turning machine will be able to meet production requirements at full capacity. An outside company, McDonald Inc., made the machine seven years ago and can…

Use information provided in table 7.8 , 7.7 (*) Use the weighted-point evaluation system to cal- culate weighted performance scores for each of the software firms. Would the results change if each dimension had a weight of one-third? (**) In Chapter 2, we described order qualifiers as per- formance dimensions on which customers demand a minimum level of performance. Basically, if a supplier fails to meet the minimum requirements on any of the qualifiers, that supplier would be eliminated from contention. How would you incorporate the concept of order qualifiers into the weighted-point evaluation system?
