1. What is the total processing time (per unit) for this manufacturing cell consisting of 3 machines?

2. What is the capacity of this manufacturing cell?

Hints:

Cell capacity= the number of units produced per day by this manufacturing cell. This would be determined by the bottleneck station.

Unit process time = cycle time/unit + setup time/batch size (batch size = 1000 units)

3. Calculate Process Cycle Efficiency for this manufacturing cell based on per unit process time.
