(Three Step) Consider a worker-paced line with three process steps, each of which is staffed with one worker. The sequence of the three steps does not matter for the completion of the product. Currently, the three steps are operated in the following sequence.
Activity time
Step #1 = 3 min/unit Step #2 = 4 min/unit Step #3 = 5min/unit
a. What would happen to the inventory in the process if the process were operated as a push system?
b. Assuming you would have to operate as a push system, how would you resequence the three activities?
c. How would you implement a pull system?
