In a simple four step manufacturing process, the scrap rates for processes 1,2,3, and 4 are 3%,4%,5% respectively. the demand is 1000 good parts per shift (8 hour shift). Assume the scrap costs for processes 1,2,3, and 4 are $5,$6,$7, and $10 respectively.
The standard times for processes 1,2,3, and 4 are 5,6,8, and 10 min respectively.
Find the number of machine fractions (don't round) needed per shift (8 hour shift) for each process. Assume 80% efficiency and 90% reliability for each process.
