5 - 8 Develop a model of a three work station serial production line with high reject rates, 5% 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. Parts rejected at the third workstation are returned to the second workstation where they are reworked. The operation times are TRIA(6, 9, 12) TRIA( b), and TRIA(5, 9, 12) for workstations 1, 2, and 3 respectively. Operations 2 and 3 have two eight hours shifts with only two (2) operators in each shift and in each work station. Operation 2 every 200 parts is stopped for maintenance. The maintenance process follows and exponential with a mean of 15 minutes. Parts interarrival times to the system UNIF (6, 14). All times are in minutes. Run the model for 20,000 minutes. 5 - 8 Develop a model of a three work station serial production line with high reject rates, 5% after each workstation.
