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).

Ron Satterfield's excavation company uses both Gantt scheduling charts and Gantt load charts. Today, which is the end of day 7, Ron is reviewing the Gantt chart depicting these schedules: Job #151 was scheduled to begin on day 3 and to take 7 days. It got started on time and is 1 day ahead of schedule. Job #177 was scheduled to begin on day 3 and take 5 days. It is currently on time. Job #179 was scheduled to start on day 6 and take 3 days. It actually got started on day 5 and is progressing according to plan. Job #211 was scheduled to begin on day 5, but missing equipment delayed it until day 6. It is progressing as expected and should take 3 days. Job #215 was scheduled to begin on day 4 and take 5 days. It got started on time but has since fallen behind 2 days. This exercise contains only part a. a) Add the actual progress to the Gantt schedule shown on the right (on which the planned timings have been already plotted as blue lines).

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…
