Problem 1. The Taylor Machine Shop rebores engine blocks. Currently, five engine blocks are waiting for processing. At any time, the company has only one engine expert on duty who can do this type of work. The engine problems have been diagnosed, and the processing times for the jobs have been estimated. Expected completion times have been agreed upon with the shop's customers. The accompanying table shows the current situation. Determine the schedule for the engine expert by using (a) the FCFS rule, (b) the SPT rule, (c) the EDD rule, and (d) the CR rule. For each rule, calculate the average flow time, average tardiness, and number of tardy jobs. If average past due is most important, which rule should be chosen
