Question:

A production system consists of four serial automatic workstations. The f rst part arrives at time zero, and then (exactly) every 9.8 minutes thereafter. All transfer times are assumed to be zero and all processing times are constant. There are two types of failures: major and jams. The data for this system are given in the table (all times are in minutes). Use exponential distributions for the uptimes and uniform distributions for repair times (for instance, repairing jams at workstation 3 is UNIF(2.8, 4.2)). Run your simulation for a single replication of 10,000 minutes to determine the percent of time each resource spends in the failure state and the ending status of each workstation queue. Animate your Resources, and put a text box in your Arena f le with the numerical results requested. Workstation Major Failure Means Jam Means Number Process Time Uptimes Repair Uptimes Repair 1 8.5 475 20, 30 47.6 2, 3 2 8.3 570 24, 36 57 2.4, 3.6 3 8.6 665 28, 42 66.5 2.8, 4.2 4 8.6 475 20, 30 47.5 2, 3
