Consider a tire factory simulation. Factory has 3 shifts, working 24 hours a day and 7 days a week. The cycle time is the parameter of interest. An initial R-10 replications, each with a total run length (that is the initialization phase plus the data collection phase) of 5991 hours are conducted. The initialization phase is taken as 1/10 of the total run length. Suppose that it is desired to estimate long-run mean cycle time to within E=0.1 hours with 95% confidence. Then, you calculated that an initial estimate of 95 replications will be needed. However, for some reason you decided to increase the total run length within each replication instead of additional replications. What should be the length of the initialization phase to achieve specified accuracy without conducing additional replications? Use hours as simulation time unit in your answer. Answer:
