Impact of Variability of Interarrival and Service Times

This chapter analyzes the influence of the distributions of some input parameters of the models on the Response times. Initially, we describe an elementary example (somewhat unrealistic) specially designed to emphasize the impact on mean Response times of different patterns of arriving requests. Then, two simple models consisting of a queue station are considered. In the first we apply different distributions to the Interarrival times of requests keeping the distribution of Service times fixed. In the second one we do the opposite: we keep the distribution of Interarrival times fixed and we consider different distributions of Service times.
