A machine shop has 20 machines in its automatic lathe section. Setup time on an automatic lathe is 10 hours. Batch size is 200 for parts processed through the section. Cycle time per part is 8 minutes. Under shop rules, an operator can be assigned to run one or two machines. Accordingly, there are ten operators in the section for the ten lathes. In addition to the lathe operators, there are two setup workers who only perform machine setups. These setup workers are busy the full shift. The section runs one 8-hour shift per day, 5 days per week. Scrap losses are negligible and availability = 100%. The production control manager claims that the capacity of the section should be 2000 parts per week. However, the actual output is only 3200 units per week. What is PC?
