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).

A manufacturer is designing a product layout for a new product production. It plans to use a production line for 8 hours per day in order to meet forecasted demand of 150 units per day. The product requires 7 tasks in total. These tasks are namely, A, B, C, D, E, F, and Grespectively. Task A does not have any predecessor to start. To start Task B, it requires Task A to be completed. Starting tasks Cneeds, the task B to be completed. Also, starting task D needed task B to be completed. Task E can only start upon completion of Task C. Whereas starting task F needs the completion of both the tasks D and E. Finally, starting task G needed, task F to be completed. The processing times for tasks, A, B, C, D, E, F. and G are 2.3, 2.1, 0.9, 1.0, 1.2, 1.8, and 1.5 minutes respectively. Applying the most remaining tasks rule for balancing the assembly line, with ties broken according to longest task time first, the tasks that will be assigned to the LAST workstation are O a. All tasks O b. Gonly…

A defense contractor in Dallas has six jobs awaiting processing. Processing time and due dates are given in the table. Assume that jobs arrive in the order shown. Compare the average completion time, utilization, average jobs in the system and average job lateness of the following scheduling rules. Start date is day 1. a) SPT: shortest processing time and b) EDD: earliest due date​​​​​​​

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). Using the line drawing tool, plot the actual…

Hi, I'm stuck on the remaining parts of this Operations Management problem. Please help. Thanks!

Given the data below, using the SPT heuristic sequencing rule, determine the completion date and tardiness for each job as well as the average completion time and average tardiness for all four jobs. Which of the following statements is true? Job Processing time (days) Due date (in days) A 10 10 B 5 8 C 15 25 D 8 15 a.Jobs B and D will have no tardiness b.The tardiness for Job A is 12 days c.The average tardiness is 19.75 d.The average completion time is 6.5

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?

K Using Johnson's rule for 2-machine scheduling, the sequence is: Scheduled Order Job C A 1 2 3 4 5 6 F D B E For the schedule developed using Johnson's rule, the total length of time taken to complete the six jobs (including the 2nd operation) hours (enter your response as a whole number). Six jobs are to be processed through a two-step operation. The first operation involves sanding, and the second involves painting. Processing times are as follows: Job A B C D E F Operation 1 (hours) 4 10 3 14 6 7 Operation 2 (hours) 8 5 11 14 1 12

24 The job that arrived first at a work center or machine will be processed first and completed. Which of the following priority rules does this statement represent?   a first come, first served   b shortest processing time   c critical ratio   d earliest due date
