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.
Job | Date Job Received | Due Date | Duration (days) | |
BR02 | 230 | 320 | 35 | |
CX01 | 235 | 360 | 40 | |
DE06 | 231 | 310 | 30 | |
RG05 | 228 | 300 | 15 | |
SY11 | 225 | 270 | 25 |
Using the FCFS (first come, first served) decision rule for sequencing the jobs, the order is:
Sequence | Job |
1 | ?? |
2 | ?? |
3 | ?? |
4 | ?? |
5 | ?? |
The total flow time for the sequence developed using the FCFS rule =??? days (round your response to two decimal places).
The percentage utilization for the sequence developed using the FCFS rule =??? %%%(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 =??? jobs (round your response to two decimal places).
The average tardiness (job lateness) for the sequence developed using the FCFS rule =??? 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 | ?? |
2 | ?? |
3 | ?? |
4 | ?? |
5 | ?? |
The total flow time for the sequence developed using the EDD rule =????? days (round your response to two decimal places).
The percentage utilization for the sequence developed using the EDD rule =??? %(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 EDD rule =?? jobs (round your response to two decimal places).
The average tardiness (job lateness) for the sequence developed using the EDD rule =??? 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):
Sequence | Job |
1 | ?? |
2 | ?? |
3 | ?? |
4 | ?? |
5 | ?? |
The total flow time for the sequence developed using the SPT rule =?? days (round your response to two decimal places).
The percentage utilization for the sequence developed using the SPT rule =?? %(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 SPT rule =???? jobs (round your response to two decimal places).
The average tardiness (job lateness) for the sequence developed using the SPT rule =??? days (round your response to two decimal places).
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 |
1 | ?? |
2 | ?? |
3 | ?? |
4 | ?? |
5 | ?? |
The total flow time for the sequence developed using the LPT rule = ???? days (round your response to two decimal places).
The percentage utilization for the sequence developed using the LPT rule =???? %%(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 LPT rule =??? jobs (round your response to two decimal places).
The average tardiness (job lateness) for the sequence developed using the LPT rule =??? days (round your response to two decimal places).
