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$/$O rule.
