Parts arrive at a single machine system according to an exponential interarrival distribution with mean 20 minutes; the f rst part arrives at time 0. Upon arrival, the parts are processed at a machine. The processing-time distribution is TRIA(11, 16, 18) minutes. The parts are inspected and for each part there is a 0.24 probability that it will need to be sent back to the same machine to be reprocessed (same processing-time distribution but a fresh draw from it, and all send-back decisions are independent of each other). There’s no limit on how many times a given part might have to go through the machine for processing/reprocessing. Run the simulation for a single replication of length 20,000 minutes to observe the average and maximum number of times a part is processed, the average number of parts in the machine queue, and the average part cycle time (time from a part’s entry to the system to its exit after however many passes through the machine system are required). Add an appropriate Resource animation.
