Assume that all of the jobs below arrived at the same time. There are three possible machines that will process these jobs: A, B, and C. Also assume that transfer times are zero and jobs cannot be split Job 1 2 3 4 5 Est. Hours A/1, B/2, C/2 A/3, C/2 B/2, A/2, C/2 C/1, B/3, A/2 A/3, C/2, B/3 Due Dates (hrs) 10 13 15 11 9 a) Calculate the critical ratio for Job 3. b) c) Using the critical ratio (CR) rule, determine the processing order. Using a Gantt chart and the processing order as per the critical ratio (CR) rule, determine the makespan. d) Using a Gantt chart and the processing order as per the critical ratio (CR) rule, determine the average flow time. e) Using a Gantt chart and the processing order as per the critical ratio (CR) rule, determine the average queue time. f) Using a Gantt chart and the processing order as per the critical ratio (CR) rule, determine the average tardiness? g) Using a Gantt chart and the processing order as per the critical ratio (CR) rule, determine the average lateness Assume that all of the jobs below arrived at the same time.
