A production system consists of four serial automatic workstations. Jobs arrive at the first
workstation as exponential with mean 8. 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 below (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 10,000
minutes to determine the percent of time each resource spends in the failure state and the
ending status of each workstation queue. Consider first 500 minutes as warm-up period.
Run the model for 5 replications and show graphically the results for single replication
and 5 replications
