The repair manager at Standard Components needs to develop a schedule for repairing eight Dell PCs. Each job requires analysis using the same diagnostic system. Furthermore, each job will require additional processing after the diagnostic evaluation. The manager does not expect any rescheduling delays, and the jobs are to move directly to the next process after the diagnostic work has been completed. The manager has collected the following processing time and scheduling data for each repair job:

a. Compare the relative performance of the FCFS, SPT, EDD, S/RO, and CR priority rules in terms of the percent of jobs past due, average days past due, and maximum days past due. 

b. Discuss the selection of one of the rules for this company. What criteria do you consider most important in the selection of a rule in this situation?
