1. Determine the utilization and the efficiency for each of these situations:
a. A loan processing operation that processes an average of 7 loans per day. The operation has a design capacity of 20 loans per day and an effective capacity of 18 loans per day.
b. A furnace repair team that services an average of 2 furnaces a day if the design capacity is 10 furnaces a day and the effective capacity is 9 furnaces a day.
c. Would you say that systems that have higher efficiency ratios than other systems will always have higher utilization ratios than those other systems?
This is not necessarily . If the design capacity is relatively , the utilization could be even though the efficiency was .
2. A small firm intends to increase the capacity of a bottleneck operation by adding a new machine. Two alternatives, A and B, have been identified, and the associated costs and revenues have been estimated. Annual fixed costs would be $39,000 for A and $30,000 for B; variable costs per unit would be $10 for A and $11 for B; and revenue per unit would be $15.
a. Determine each alternative's break-even point in units. (Round your answer to the nearest whole amount.)
b. At what volume of output would the two alternatives yield the same profit? (Round your answer to thenearest whole amount.)
c. If expected annual demand is 16,000 units, which alternative would yield the higher profit?
3. A company manufactures a product using machine cells. Each cell has a design capacity of 250 units per day and an effective capacity of 230 units per day. At present, actual output averages 200 units per cell, but the manager estimates that productivity improvements soon will increase output to 224 units per day. Annual demand is currently 60,000 units. It is forecasted that within two years, annual demand will triple. How many cells should the company plan to acquire to satisfy predicted demand under these conditions? Assume that no cells currently exist. Assume 242 workdays per year.
4. The following diagram shows a 4-step process that begins with Operation 1 and ends with Operation 4. The rates shown in each box represent the effective capacity of that operation.
Determine the capacity of this process.
5. A manager must decide which type of machine to buy, A, B, or C. Machine costs (per individual machine) are as follows:
|

A
|
$ 80,000
|

$ 70,000

a. Assume that only purchasing costs are being considered. Compute the total processing time required for each machine type to meet demand, how many of each machine type would be needed, and the resulting total purchasing cost for each machine type. The machines will operate 10 hours a day, 240 days a year.
b. Consider this additional information: The machines differ in terms of hourly operating costs: The A machines have an hourly operating cost of $12 each, B machines have an hourly operating cost of $14 each, and C machines have an hourly operating cost of $15 each. What would be the total cost associated with each machine option, including both the initial purchasing cost and the annual operating cost incurred to satisfy demand?
