Parts arrive at a machine system according to an exponential distribution with a mean of 20 minutes. The machine processes parts with a triangular distribution of 11-16-18 minutes. 25% of parts are sent for reprocessing with the same time. The simulation was run for 20,000 minutes and recorded average and maximum parts in the machine and inspection queues, number of parts processed, and average part cycle time.

2. Parts arrive at a single machine system according to
an exponential inter-arrival 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 parts in Machine and in Inspection queue,
Number of parts processed and Average part cycle
time.

4. Number of Parts Processed : 993
Average Part Cycle Time : 4.18 minutes
Average Parts in Machine Queue : 8.98
Average Parts in Inspection Queue : 1.631
Maximum Parts in Machine Queue : 21
Maximum Parts in Inspection Queue : 6
