M& m's get processed in a three-station production line. first the chocolate is shaped into its round shape, then it gets coated, and final the "m" is sprayed on each individual m& m. station 1 has five identical machines with average processing times of 15 seconds per job station 2 has 12 identical machines with average processing times of 30 seconds per job. station 3 has one machine with average processing time of 3 seconds per job.
a.) what are the bottleneck rate, rb, the raw process time to, and the critical wip wo?
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
iii.) the practical worst case
c.) suppose you desire the throughput of a line to be 90 percent of the bottleneck rate. find the wip level required to achieve this under the assumptions of:
i.) the best case
ii.) the worst case
iii.) the practical worst case
