Consider a production line with three single-machine


Question: Consider a production line with three single-machine stations in series. Each has processing times with mean 2 hours and standard deviation of 2 hours. (Note that this makes it identical to the line represented in the practical worst case of Chapter 7.) Since it is not given, assume SCV for arrivals = 1.

a). Suppose we run this line as a push system and release jobs into it at a rate of 0.45 per hour with arrival variability give by ca = 1. What is the average WIP in the line?

b). Compute the throughput of this line if it is run as a CONWIP line with a WIP level equal to your answer in (a). Is the throughput higher or lower than 0.45? Explain this result.
