A. Using the FCFS (first come, first served) decision rule for sequencing the jobs, the order is:

Sequence Job

1

2

3

4

5

1. The total flow time for the sequence developed using the FCFS rule =

2. The percentage utilization for the sequence developed using the FCFS rule =

3. The average number of jobs in the system for the sequence developed using the FCFS rule =

4. The average tardiness (job lateness) for the sequence developed using the FCFS rule =

B. Using the EDD (earliest due date) decision rule for sequencing the jobs, the order is (to resolve a tie, use the order in which the jobs were received):

Sequence Job

1

2

3

4

5

1. The total flow time for the sequence developed using the EDD rule =

2. The percentage utilization for the sequence developed using the EDD rule =

3. The average number of jobs in the system for the sequence developed using the EDD rule =

4. The average tardiness (job lateness) for the sequence developed using the EDD rule =

C. Using the SPT (shortest processing time) decision rule for sequencing the jobs, the order is (to resolve a tie, use the order in which the jobs were received):

Sequence Job

1

1. The total flow time for the sequence developed using the SPT rule =

2. The percentage utilization for the sequence developed using the SPT rule =

3. The average number of jobs in the system for the sequence developed using the SPT rule =

4. The average tardiness (job lateness) for the sequence developed using the SPT rule =

D. Using the LPT (longest processing time) decision rule for sequencing the jobs, the order is (to resolve a tie, use the order in which the jobs were received):

Sequence Job

4. The average tardiness (job lateness) for the sequence developed using the LPT rule =

The following jobs are waiting to be processed at Rick Solano's machine center. Solano's machine center has a relatively long backlog and sets a fresh schedule every 2 weeks, which does not disturb earlier schedules. Below are the jobs to be scheduled today, which is day 241 (day 241 is a work day). Job names refer to names of clients and contract numbers. Compute all times based on initiating work on day 241.
