parts arrive at a single machine system according to an exponential interarrival distribution with mean 20 minutes;
the first 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 about 25% are sent back to the same machine to be reprocessed (same processing time) .Run the simulation for 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) |
