Parts arrive at a two-machine system according to an exponential interarrival distribution with a mean of 20 minutes. Upon arrival, the parts are sent to Machine 1 and processed. The processing-time distribution is TRIA (4.5, 9.3, 11) minutes. The parts are then processed at Machine 2 with the processing-time distribution as TRIA (16.4, 19.1, 20.8) minutes. The parts from Machine 2 are directed back to Machine 1 to be processed a second time with the same processing-time distribution but an independent draw from it. The completed parts then exit the system. There are transfer times between part arrival and Machine 1, between machines, and between the last Machine 1 and system exit. All parts transfer times are UNIF (1.5, 3.1).
Run the simulation for a single replication of 20,000 minutes to observe the average number in the machine queues and the average part cycle time with Arena Model.
