Q. a) Illustrate what are the bottleneck rate, the raw process time and the critical WIP?

b) Compute the average cycle time when the WIP level is set at 20 jobs, under the assumptions of i) the best case, ii) the worst case and iii) the practical worst case.

c) Assume you want during put of the line to be 90% of the bottleneck rate. Find the WIP level required to achieve this under the assumptions of i) the best case, ii) the worst case and iii) the practical worst case.

d) If the cycle time at the critical WIP is 100 min., where does performance fall relative to the 3 cases? Is there much room for improvement?
