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…
DuLarge Marine manufactures diesel engines for shrimp trawlers and other small commercial boats. One of their automated machines has caused several problems.

For an additional fee, a customer purchasing a Whirlpool appliance, such as washing machine, can purchase a three year service contract. The contract provides free repair service and parts for the specified appliance using an authorized Whirlpool service provider. When a person with Whirlpool service contract needs to repair an appliance such as washing machine, he or she calls the whirlpool repairs and parts department to schedule an appointment. The department makes the appointment and gives the caller the date and approximate time of the appointment. This process is very lengthy. It may take two weeks to schedule a repair visit.In above case what changes could be made to make this process more efficient with the development of Information system.
