Please answer Problem 4. I've included the information necessary from Problem 3. Thanks! :)

hree time MGT 321 Operations Management Assignment 7: 50 pts Chapter 13 1. Problem 3 Sequence the jobs shown below by using a Gantt chart. Assume that the move time between machines is one hour. (i.c.- When a job is complete on it's first workstation, it must wait 1 hour (move time) before it begins on the next station) Example of Move Time Machine A111 Machine 11111 Sequence the jobs in priority order 1,2,3,4. Assume 8hr work days. Job Werk Center Machine Hours Due Date (Days) 1 1/3, B2, C2 2 02.14 3 B6, N1.CH 4 C4. NI. B/2 a) What is the total makespan? b) How much machine idle time is there? c) When is each job delivered compared with its due date? d) How much idle time (waiting time) is there for each job? e) Devise a better job sequence for processing. 2. Problem 4 In problem 3, assume there are two machines of type A, two of type B, and two of type C. a) Prepare a finite capacity schedule b) How does your FCS compare to the performance of the Gantt chart in problem 2? Solution : a: Makespan is 18 days. 9 10 11 12 13 14 15 16 17 18 8 41 B 3 4 4 3 A B Job Workcent 1 2 3 4 5 6 7 1 2 1 2 Solution : b: Machine idle times are: A - 9 hours, B - 8 hours, C - 7 hours Machine Working Hours Idle Hours 9 9 10 8 11 Solution : c: Job completion is well before due dates.
