A proposed production system consists of five s automatic workstations. The processing times at each workstation are constant: 11, 10, 11, 11, and 12 (all times given in this exercise are in minutes). The part interarrival times are UNIF (13.0, 15.1).
There is an unlimited buffer in front of all workstations, and we will assume that all transfer times are negligible or zero. The unique aspect of this system is that at workstations 2 through 5 there is a chance that part will need to be reprocessed by the workstation precedes it.
For that the back to the queue in example, after completion at workstation 2, the part can be sent back to the queue in front of workstation 1.
The probability of revisiting a workstation is independent in that same part could be sent back many times with no change in the probability.
At present, it is estimated that this probability, the same for all four workstations, will be between 5% 10%. Develop the simulation model and make six runs.
