Management has asked for your help in computing throughput time, delivery cycle time, and MCE. The following average times have been logged over the last four months: Average per Month (in days)
1 2 3 4
Move time per unit 0.4 0.3 0.4 0.4
Process time per unit 2.1 2.0 1.9 1.8
Wait time per order before
start of production 16.0 17.5 19.0 20.5
Queue time per unit 4.3 5.0 5.8 6.7
Inspection time per unit 0.6 0.7 0.7 0.6
Required:
1-a. Compute the throughput time for each month.
1-b. Compute the delivery cycle time for each month.
1-c. Compute the manufacturing cycle efficiency (MCE) for each month.
2. Evaluate the company’s performance over the last four months.
3-a. Refer to the move time, process time, and so forth, given for month
4. Assume that in month 5 the move time, process time, and so forth, are the same as in month 4, except that through the use of Lean Production the company is able to completely eliminate the queue time during production. Compute the new throughput time and MCE.
3-b. Refer to the move time, process time, and so forth, given for month
4. Assume in month 6 that the move time, process time, and so forth, are again the same as in month 4, except that the company is able to completely eliminate both the queue time during production and the inspection time. Compute the new throughput time and MCE.
