T. Smunt Manufacturing Corp. has the process displayed below. The drilling operation occurs separately from and simultaneously with the sawing and sanding operations. The product only needs to go through one of the three assembly operations (the assembly operations are “parallel”). 

See attached image with outline

a.    Which operation is the bottleneck? 

b.    What is the throughput time (time from start to finish for one unit) of for the overall system?

c.    If the firm operates 8 hours per day, 22 days per month, what is the monthly capacity of the manufacturing process?

d.    Suppose that a second drilling machine is added, and it takes the same time as the original drilling machine. What are the new bottleneck operation and the bottleneck time?

e.    Suppose that a second drilling machine is added, and it takes the same time as the original drilling machine. What is the new throughput time?

f.    Suppose that a second drilling machine is added, and it takes the same time as the original drilling machine. What is the new the monthly capacity of the manufacturing process?

g. Show the process how to solve (step by step calculation)
