A small manufacturing department contains three serial workstations (that is, parts go through each of the three workstations in order, one workstation after the other). Parts arrive according to an exponential interarrival-time distribution with mean 8 (all times are given in minutes), with the f rst part’s arriving at time 0. Before a new part can start processing, it must be mounted on a special f xture, and this mounting operation takes 2 minutes (there are four f xtures available, which can be reused, but each f xture can carry only one part at a time). The part remains on the f xture until it completes processing on all the workstations, at which time it is removed from the f xture (this removal operations takes 1 minute), after which the f xture becomes available for another part that might be waiting for it. Processing times at the f rst workstation follow a triangular operation time with minimum 4, mode 7, and maximum 9. Processing times at the second workstation have a uniform distribution between 5 and 10. Processing times at the third workstation have a triangular operation time with minimum 5, mode 6.5, and maximum 9. Run your simulation for a single replication of length 48 hours, and observe the time-average and maximum total work in process (WIP) in the whole system. At each workstation separately, observe the average and maximum queue lengths, and the resource utilization. Also observe the utilization of the four f xtures as a group, as well as the time-average and maximum number of parts that are waiting for a f xture (before they can even get going into the system for processing). Add a plot for the total WIP and by-workstation queue lengths, all on the same set of axes; add a second plot showing the number of f xtures that are in use. Animate the resources and queues for each of the workstations, and animate the parts waiting for a f xture, but do not animate the f xtures themselves. Put in a text box with the numerical results requested. What appears to be the bottleneck in this system preventing better eff ciency? HINT: Remember that an entity can have multiple different resources Seized at the same time, and that the Process module has “Action” options other than the usual Seize-Delay-Release.
