Consider a three-step process. Each step is staffed with one or more workers. The steps are operated in the following sequence: Do step 1 first, then step 2, and finally step 3. Assume there is a large buffer storage in front of every step. Also, there is sufficient input raw material at Step 1. There is unlimited demand.
Steps Processing time (min/unit) Number of workers 1 10 2 2 16 1 3 6 3
If the process is operated using the push system, what are the approximate utilizations of Steps 1, 2 & 3, respectively?
a. The utilizations are 100%, 100% and 13%, respectively.
b. The utilizations are 26%, 8% and 66%, respectively.
c. The utilizations are 31%, 100% and 40%, respectively.
d. The utilizations are 100%, 31% and 100%, respectively.
