A foreman has determined processing times at a work center for a set of jobs and now wants to sequence them. Given the information shown, do the following:
a. Determine the processing sequence using (1) FCFS, (2) SPT, (3) EDD, and (4) CR. For each sequence, compute the average job tardiness, the average flow time, and the average number of jobs at the work center. The list is in FCFS order.
b. Using the results of your calculations in part a, show that the ratio of average flow time and the average number of jobs measures are equivalent for all four sequencing rules.
c. Determine the processing sequence that would result using the S/ Orule.
