A. Find the capacity (in units/day) of each step. Please show your work.

Step	A	B1	B2	C1	C2	D
Capacity (units/day)

B. Find the capacity (in units/day) of the process. Hint: consider B1-C1 and B2-C2 as subprocesses and then consider B1-C1&B2-C2 as one aggregate step. Please show your work.

C. Suppose the process is running at 90% capacity. Find the overall labor utilization. Please show your work.

1. A product requires four steps, A, B, C and D. Two alternative paths exist for steps B and C. Each unit can either go through B1-C1 or B2-C2. The total number of workers in the process is 13 and they are assigned to the steps of the process as shown in the table below. The table also shows the processing time for one worker to finish a unit in each step. Each worker works 8 hours ( 480 minutes) a day
