ARENA: Develop a model of a serial two-process system. Items arrive at the system with an unknown inter-arrival distribution, with the first item arrives at time 0. They are immediately sent to Process 1, which has a single resource with an unknown service time distribution. Upon completion, they are sent to Process 2, which is identical to (but independent of) Process 1. Items depart the system upon completion of Process 2. Performance measures of interest are the time-average numbers in queue at each process and the average total time in system of items.

1. Using the provided inter-arrival and service time data provided, determine the distribution of inter-arrival and service time distributions (Explain results of your statistical tests).

1. Using the distribution you determined, build the model in ARENA and run the problem for a single replication of length 10,000 minutes. What are the time-average numbers in queue at each process and the average total time in system of items?
