- A production process at Kenneth Day Manufacturing is shown in Figure S7.9. The drilling operation occurs separately from, and simultaneously with, sawing and sanding, which are independent and sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel).a) Which operation is the bottleneck?b) What is the bottleneck time?c) What is the throughput time of the overall system?d) If the firm operates 8 hours per day, 20 days per month, whatis the monthly capacity of the manufacturing process?arrow_forwardA production schedule requires six work stations. However, there are nine work tasks to be performed to produce a unit of output. The warchouse is operated for seven days a week and three 8-hour shifts per day.
