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

Sequence	Job
1	SY-11

2

RG-05

3

BR-02

4

DE-06

5

CX-01

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

390390

days (round your response to two decimal places).The percentage utilization for the sequence developed using the FCFS rule =

37.1837.18%

(enter your response as a percentage rounded to two decimal places).The average number of jobs in the system for the sequence developed using the FCFS rule =

2.692.69

jobs (round your response to two decimal places).The average tardiness (job lateness) for the sequence developed using the FCFS rule =

1212

days (round your response to two decimal places).

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	SY-11

2

RG-05

3

DE-06

days (round your response to two decimal places).

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):

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.
