An average cycle time of 100+-20 seconds was obtained from a simulation of 10 replications. If we want to reduce the half-width to \pm 10 (without changing the length of replication), what should be the number of replications? In Model 7-1 (posted on Blackboard), suppose we can add another machine to Cell 1 or Cell 2 , only to one of them. The additional machine will be identical to the existing machine at the cell, so adding a machine will increase the capacity at the cell. The key performance measure is the total production = EntitiesOut(Part 1) + EntitiesOut(Part 2) + EntitiesOut(Part 3). To which cell should we add the additional machine to maximize the total production? Is there any
