Chapter 13, Problem 41P

A manager is going to purchase new processing equipment and must decide on the number of spare parts to order with the new equipment. The spares cost $200 each, and any unused spares will have an expected salvage value of $50 each. The probability of usage can be described by this distribution:

Chapter 13, Problem 41P, A manager is going to purchase new processing equipment and must decide on the number of spare parts

If a part fails and a spare is not available, two days will be needed to obtain a replacement and install it. The cost for idle equipment is $500 per day. What quantity of spares should be ordered?

a. Use the ratio method.

b. Use the tabular method (see Table 13.3).

An injection molding system has a first cost of $90,000, and an annual operating cost of $42,000 in year 1, increasing by $5000 per year thereafter. The salvage value of the system is 30,000 if you sell after 1 year of use. The salvage value decreases by $5,000 each year thereafter. The maximum useful life of the machine is 4 years. Using a MARR of 20% per year, determine the ESL and the corresponding Equivalent Annual Cost of the system.
- Mom-and-Pop’s Grocery Store has a small adjacent parking lot with three parkingspaces reserved for the store’s customers. During store hours, cars enter the lot and useone of the spaces at a mean rate of 2 per hour. For n = 0, 1, 2, 3, the probability Pn that exactly n spaces currently are being used is P0 = 0.1, P1 = 0.2, P2 = 0.4, P3 = 0.3. - Midtown Bank always has two tellers on duty. The Customers arrive at checkouts at an average rate of 40 per hour. A cashier requires an average of 2 minutes to serve a customer. When both cashiers are busy, arriving customer joins a queue and wait to be served. From experience it is known that customers They wait in line for an average of 1 minute before going to the checkout. a) Describe why this is a waiting line system Mention the queuing model that can be implemented for the analysis (notation of Kendall) and why that model was chosen
A 3 year-old a computer-controlled fabric cutting machine, which had a $25,000 purchasing price, has a current market (trade-in) value of $10,000 and expected O&M costs of $4,000, increasing by 1,000 per year. The machine is required to have an immediate repair that costs $2,000. The estimated market values are expected to decline by 20% annually (going forward). The machine can be used for another 7 years at most. The new machine has a $40,000 purchasing price. The new machine's O&M cost is estimated to be $4,000 for the first year, decreasing at an annual rate of $100 thereafter. The firm's MARR is 10%. Assume a unique minimum AEC(10%) for both machines (both the current and replacement machine). Using the information above, determine the economic service life along with the optimum annual equivalent cost of the defender (This is an infinite Horizon decision problem). a) n=4 and AEC=Between $8,400 and $8,800 b) n=4 and AEC=Between $8,000 and $8,400 c) n=5 and AEC=Between $8,400 and…
