Question:
A proposed production system consists of f ve serial 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 the part will need to be reprocessed by the workstation that precedes it. For 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 the 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% and 10%. Develop the simulation model and make six runs kel01315_ch04_121-206.indd 196 05/12/13 3:29 PM Modeling Basic Operations and Inputs 197 of 10,000 minutes each for probabilities of 5%, 6%, 7%, 8%, 9%, and 10%. Using the results, construct a table (put this table inside your .doe f le using an Arena Text box) of the average cycle time (system time) against the probability of a revisit. Also include the maximum cycle time for each run in your table.
