Using the model from Exercise 4-2, set the interarrival-time distribution to exponential and the process-time distribution for each Process to uniform on the interval [9 − h , 9 1 h ]. Setting the value of h to 1.732, 3.464, and 5.196, compute the (exact) variance of this distribution and make three different runs of 100,000 minutes each and compare the results. Note that the mean of the process time is always 9 and the distribution form is always the same (uniform); the standard deviation (and thus the variance) is the only thing that’s changing.
