For the production of part R-193, two operations are being considered. The capital investment associated with each operation is identical. Operation 1 produces 2,000 parts per hour. After each hour, the tooling must be adjusted by the machine operator. This adjustment takes 20 minutes. The machine operator for Operation 1 is paid $20 per hour (this includes fringe benefits). Operation 2 produces 1,750 parts per hour, but the tooling needs to be adjusted by the operator only once every two hours. This adjustment takes 30 minutes. The machine operator for Operation 2 is paid $11 per hour (this includes fringe benefits). Assume an 8-hour workday. Further assume that all parts produced can be sold for $0.40 each. Should Operation 1 or Operation 2 be recommended?

For the production of part R-193, two operations are being considered. The capital investment associated with each operation is identical. Operation 1 produces 2,100 parts per hour. After each hour, the tooling must be adjusted by the machine operator. This adjustment takes 15 minutes. The machine operator for Operation 1 is paid $24 per hour (this includes fringe benefits). Operation 2 produces 2,350 parts per hour, but the tooling needs to be adjusted by the operator only once every two hours. This adjustment takes 45 minutes. The machine operator for Operation 2 is paid $13 per hour (this includes fringe benefits). Assume an 8-hour workday. Further assume that all parts produced can be sold for $0.35 each. a. Should Operation 1 or Operation 2 be recommended? b. What is the basic tradeoff in this problem?

Determine the minimum-cost trade-off between the MTBF and the MTTR for a system requiring 0.98 availability. The MTTR must be between 10 and 28 hr, and the MTBF must be at least 1200 hr. Consider the cost functions as: a. C(x) = 0.0002x2 ; C(y) = 12500/y b. C(x) = 2x; C(y) = 2000-y 2.

A enterprise budget for corn shows total operating expenses of $405 per acre and total ownership expenses of $145. If yields are assumed to be 150 bu/ acre, what is the lowest price a producer could accept ( and therefore produce) if the production decision is in the short run?
