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?

There are four stations in a process: Station-1, Station-2, Station-3, and Station-4. They process a single product. The flow of the accepted and rejected products are shown in the process flow chart. The total volume of production is 105 products per hour. 23% of the products of Station-1 need repair and are directed to Station-3 for repair, the rest are sent to Station-2. 15% of the products of Station-2 need repair and are directed to Station- 3 for repair, the rest are sent to Station-4. 12% of the incoming products of Station- 3 are rejected, are sold at a low price, and leave the process. The rest go to Station-4. All the products of Station-4 are good, no need to repair, and no rejection. On average there are 8, 2. 40, and 5 products in Stations 1, 2, 3, 4, respectively.
