Job Job Processing Time (days) 17 Job Due Date (days) 38 A B 12 29 21 32 D 8 41 a. b. Sequence the jobs using (1) FCFS, (2) SPT, (3) EDD, and (4) CR. [10 Marks] For each of the rules in part a, determine (1) the average job flow time; (2) the average tardiness, and (3) the average number of jobs at the work centre. Which rule would you choose based on the three measures of effectiveness? [20 Marks] Question 2 [20 marks) The following table shows the time required to complete each of seven jobs in a two-step service process. Each job must follow the same sequence, beginning with Step 1 and moving to Step 2. The job times in hours) of these seven jobs are given in the following table. A B D E F G Job Step 1 Step 2 12 14 5 10 14 10 8 11 10 12 9 6 7 12 a.
