Question

Management of Mittel Rhein AG of Köln, Germany, would like to reduce the amount of time between when a customer places an order and when the order is shipped. For the first quarter of operations during the current year the following data were reported: Inspection time 0.3 days Wait time (from order to start of production) 14.0 days Process time 2.7 days Move time 1.0 days Queue time 5.0 days
1.Compute the throughput time.
2. Compute the manufacturing cycle efficiency (MCE) for the quarter. (Round your answer to 2 decimal places.)
3. What percentage of the throughput time was spent in non–value-added activities? (Enter your answer as a percentage (i.e., 0.12 should be entered as 12).)
4.Compute the delivery cycle time.
5. If by using Lean Production all queue time during production is eliminated, what will be the new MCE? (Round your percentage answer to 1 decimal place (i.e., 0.123 should be entered as 12.3).)

Answer 1

Answer:

1. The throughput time is 9 days

2. The MCE is 0.30

3. 70% of the throughput time was spent on non-value added activities.

4. The delivery cycle time is 23 days

5. The New MCE is 67.5%

Explanation:

1. To calculate the throughput time we would have to use to make the following calculation:

throughput time=process time+inspection time+movie time+queue time

throughput time=2.7+0.3+1+5

throughput time=9 days

2. To calculate the MCE we would have to use to make the following calculation:

MCE=value added time/throughput time

MCE=2.7/9=0.30

3. MCE is 30% which means that out of the total throughput time, time spent on value added activities was 30%. Thus it means that 70% of the throughput time was spent on non-value added activities.

4. To calculate the delivery cycle time we would have to use to make the following calculation:

delivery cycle time=wait time+throughput time

delivery cycle time=14+9=23 days

5. To calculate the new MCE we would have to use to make the following calculation:

New MCE=value added time/throughput time

New MCE=2.7/4

New MCE=67.5%
