Develop a model of a three-workstation serial production line with high reject rates: 7% after each workstation. Parts rejected after  the first workstation are sent to scrap. Parts rejected after the second  workstation are returned to the first workstation where they are reworked,  which requires a fresh "draw" from the processing-time distribution  but increased by 50% from the distribution of the original operation. (This  penalty factor of 1.5 applies only at Workstation 1 and not at Workstation 2  when the part returns to it.) Parts rejected at the third workstation are  returned to the second workstation where they are reworked, with a 50% penalty  there (but not on its revisit to Workstation 3). The operation times are  TRIA(6, 9,12), TRIA(5, 8.5,13), andTRIA(6.5, 8.9, 12.5) for workstations 1, 2  and 3 respectively (all times are in minutes). Part interarrival times to the  system are UNIF(6,14). Run the model for 20,000 minutes, collecting statistics  on the number in queue at each workstation, the number of scrapped parts,  workstation utilizations, and average and maximum cycle times for parts that  are not rejected at any workstation and for parts that are rejected at least  once. Also, collect statistics on the number of times a rejected part was  rejected.
