3) to final assembly for an important customer order. Currently, all eight jobs are in department X and must be routed to department Y after processing. The processing times (in days) for each job in each department follow: The machine shop of Reliable Manufacturing has to schedule eight jobs that are to be sent Dept/Job Dept. X Dept. Y A B C D E F G H 2 4 7 5 4 10 3 3 8 2 6 5 Develop two schedules for operations in both departments. For your first schedule, use the SPT priority rule (based on X). Your second schedule should be based on Johnson's Rule. Compare the two schedules using average flow time, makespan, and average WIP inventory. Use a Gantt chart to display your schedules (i.e. a timeline).

What is the answer

At the campus copy shop, six jobs have a rrived in the order shown (A, B, C, D, E, and F) at the beginning of the day (today, which is a workday). All of the jobs are due at varioustimes today. Your task is to evaluate four common sequencing rules.                                                      a) Sequence the jobs according to the following decision rules:FCFS, EDD, SPT, and LPT.b) For the FCFS sequence, compute the average completion (flow) time, average lateness, and average number of jobs in the system.c) For the EDD sequence, compute the average completion (flow) time, average lateness, and average number of jobs in the system.d) For the SPT sequence, compute the average completion (flow) time, average lateness, and average number of jobs in the system.                                                                                                                  e) For the LPT sequence, compute the average completion (flow)time, average lateness, and average number of jobs…

The following jobs are waiting to be processed at the same machine center. Jobs are  logged as they arrive:                                                                                                                                                           In what sequence would the jobs be ranked according to the following decision rules:            (a) FCFS, (b) EDD, (c) SPT, and (d) LPT? Alldates are specified as manufacturing planning ca.lendar days. Assumethat all jobs arrive on day 275. Which decision is best and why?

5. Draw the Gantt Chart of M1, M2, M3. Due dates of the jobs are 16,14,10,8 in order. Use "FIFO" Processing Time (min) Routing Process and Machine Number OP-1 OP-3 OP-1 OP-2 OP-3 Job-1 4/M1 3/M2 2/M3 Job-2 1/M2 4/M1 4/M3 M1 M3 M2 M3 Job-3 3/M3 2/M2 3/M1 Job-4 3/M2 3/M3 1/M1 M3 M1 M2 M1 Job-1 Job-2 Job-3 Job-4 OP-2 M2 M1 M2 M3

Evan Schwartz has six jobs waiting to be processedthrough his machine. Processing time (in days) and duedate information for each job are as follows:Sequence the jobs by FCFS, SPT, SLACK, and DDATE.Calculate the mean flow time and mean tardiness of the sixjobs under each sequencing rule. Which rule would yourecommend?
