Kits of ceiling fans arrive at an assembly system with tria(2, 5, 10) interarrival times (all times are in minutes). there are four assembly operators, and the kits are automatically sent to the first available operator for assembly. the fan assembly time is operator-dependent as given. operator assembly time tria(15, 18, 21) tria(16, 19, 22) tria(16, 20,24) tria(17, 20, 23) upon completion of the assembly process, the fans are inspected with approx imately 7% being found defective. a defective fan is sent back for repair to the same operator who assembled it. these defective fans have non-preemptive priority over incoming kits. since the fan needs to be disassembled and then reassembled, the repair time is assumed to be 30% greater than the normal assembly time. run your model for 20,000 minutes and collect statistics on operator utilization and the time in system
