Question
Consider a three-stage process with the stage named as Process A, Process B and Process C. Input comes into Process A. Output form A goes into Process B. Output from B goes into Process C. Output of C is the final output. Suppose that it takes 2 minutes per unit in Process A, 3 minutes per unit in Process B, and 1 minute per unit in Process C. Suppose further that Process A receives input at the rate of 30 per hour. Where would you place a buffer? In front of Process B In front of Process C In front of Process A In front of both Process B and Process C
Explanation / Answer
Processing time of process B is the maximum. Therefore, it is the longest bottleneck.
Buffer is placed right before the bottleneck, to ensure that workflow runs smoothly and deal with fluctuations in production system.
Therefore, buffer is placed in front of process B.
