Complete question is;
Waltner Corporation's management reports that its average delivery cycle time is 25 days, its average throughput time is 7.7 days, its manufacturing cycle efficiency (MCE) is 0.43, its average move time is 0.3 day, and its average queue time is 3.00 days. Required: a. What is the wait time?
b. What is the process time?
c. What is the inspection time?
Answer:
A) Wait time = 17.3 days
B) Process time = 3.311 days
C) Inspection time = 0.789 days
Explanation:
A) we are given;
Delivery cycle time = 25 days
throughput time = 7.7 days
The formula for wait time is calculated from;
Delivery time = wait time + throughput time
So, wait time = Delivery time - throughput time
Wait time = 25 - 7.7 = 17.3 days
B) The process time is calculated from;
MCE = Process time/throughput time
So, process time = MCE x throughput time
We are given MCE = 0.43,thus, and we already know throughput time. Thus;
Process time = 0.43 x 7.7 = 3.311 days
C) The inspection time is gotten from;
throughput time = Process time + Inspection time + Move time + Queue time
Making inspection time the subject;
inspection time = throughput time - Process time - Move time - Queue time
Move time = 0.3 days
Queue time = 3 days.
Thus;
inspection time = 7.7 - 3.311 - 0.3 - 3.3 = 0.789 days
