10 The saga of Joe from Chapter 17 (Problem 13, page 687) continues. Joe has the opportunity to do a big repair job for a local motorcycle club. (Their cycles were accidentally run over by a garbage truck.) The compensation for the job is good, but it is vital that the total repair time for the five cycles be less than 40 hours. (The leader of the club has stated that he would be very distressed if the cycles were not available for a planned rally.) Joe knows from experience that repairs of this type often entail several trips between processes for a given cycle, so estimates of time are difficult to provide. Still, Joe has the following historical data about the probability that a job will start in each process, processing time in each process, and transitional probabil- ities between each pair of processes:

Given this information, use simulation to determine the repair times for each cycle. Display your results on a Gantt chart showing an FCFS schedule. (Assume that only one cycle can be worked on at a time in each process.) Based on your simulation, what do you recommend Joe do next?
