Develop a model of a simple serial two-process system. Items arrive at the systemwith a mean time between arrivals of 10 minutes, with the first arrival at time 0. Theyare immediately sent to Process 1, which has a single resource with a mean service timeof 9.1 minutes. Upon completion, they are sent to Process 2, which is identical to (butindependent of) Process 1. Items depart the system upon completion of Process 2. Per-formance measures of interest are the time-average numbers in queue at each processand the average total time in system of items; put a text box in your model with each ofthese performance measures' values for each of the four run conditions listed. Using asingle replication of length 10,000 minutes, make the following four runs and comparethe results (noting that the structure of the model is unchanged, and it's only the inputdistributions that are changing): Run 1: exponential interarrival times and exponential service times Run 2: constant interarrival times and exponential service times Run 3: exponential interarrival times and constant service times Run 4: constant interarrival times and constant service times SPECIFY WHICH RUN IS WHICH
