Chapter 12, Problem 7P

At the University Hospital, five blood samples must be scheduled through a blood-testing laboratory. Each sample goes through up to four different testing stations. The times for each test and the due dates for each sample are as follows:

Sample	Test Station /Hours	Due Date (hours)
1	A/1, B/2, C/3, D/1	6
2	B/2, C/3, A/1, D/4	10
3	C/2, A/3, D/1, C/2	8
4	A/2, D/2, C/3, B/1	14
5	D/2, C/l, A/2, B/4	12

1. a. Using a Gantt chart, schedule these five samples in priority order of earliest due date first.
2. b. Assume that the capacity of each test station (A, B, C, and D) is doubled. Prepare an FCS for this situation.
3. c. What are the bottleneck work centers in part a of the problem. Suggest capacity additions that might be needed002E
