Schurz Corporation's management reports that its average delivery cycle time is 28 days, its average throughput time is 13.0 days, its manufacturing cycle efficiency (MCE) is 0.40, its average move time is 0.6 day, and its average queue time is 3.0 days.
Required:
a. What is the wait time? (Round your answer to 1 decimal place.)
b. What is the process time? (Round your answer to 1 decimal place.)
c. What is the inspection time? (Round your intermediate calculations and final answer to 1 decimal place.)
Navern Corporation manufactures and sells custom home elevators. From the time an order is placed until the time the elevator is installed in the customer’s home averages 59 days. This 59 days is spent as follows:
| Wait time | 12 | days |
| Inspection time | 7 | days |
| Process time | 17 | days |
| Move time | 16 | days |
| Queue time | 7 | days |
What is Navern's manufacturing cycle efficiency (MCE) for its elevators?
| Answer |
|
Wait time = Delivery cycle time - Throughput time = 28 days - 13.0 days = 15 days |
| Process time = MCE × Throughput time = 0.40 × 13 days = 5.20 days |
| Inspection time = Throughput time - Process time - Move time - Queue time = 13 days - 5.2 days - 0.6 day - 3 days = 4.2 days |
| Answer |
| Manufacturing cycle efficiency=Processing time/(Process time+Inspection time+Move time+Queue time) |
| =17 days/(17+7+16+7)days |
| =17/47 |
| which is equal to |
| =36.17% |
