Please correct

Five jobs are ready for processing at time zero through a workstation. The details of the processing time and the due date of completion is provided in the following table. Job A B Processing Time (days) I5 Due Date 11 6 3 16 19 10 D E 15 Using the earliest due date (EDD) rule, the average lateness for the five jobs is decimal place. Round your answer to one Your Answer: Answer

What is the answer

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

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?

The following jobs are waiting to be processed at a small machine center; JOB 10 20 30 40 50 days (round your response to one decimal place). DUE DATE 260 254 260 265 275 days (round your response to one decimal place). DURATION (DAYS) All dates are specified as manufacturing planning calendar days. Assume that all jobs arrived on day 200 (yesterday) in the order shown but are not scheduled to begin until day 201 (today). a) Sequence the jobs according to LPT. According to the LPT rule, the sequence of jobs should be 50, 20, 10, 30, 40 b) What is the average completion (flow) time? The average completion (flow) time is c) What is the average job lateness? The average job lateness is d) What is the average number of jobs in the system? The average number of jobs in the system is jobs (round your response to one decimal place). 18 22 14 4 32

Five jobs are planned to be scheduled. Each of the jobs must be processed on three machines (A, B, and C) in the same order. The processing times are listed below. Use Johnson's Rule to determine the optimal sequence of jobs. Job B 16 10 11 10 14 20 12 3 10 8 4 1 O a) 3-1-2-4-5 O b) Johnson's Rule is not an Optimal Technique O c) 1-2-3-4-5 O d) 5-4-3-1-2 O e) 5-4-3-2-1 O) 5-4-2-1-3 O e) 5-4-2-3-1 2345

Given the projects displayed in Table 18.21, if SPT is used to sequence the jobs, what isthe average flow time of the projects (in hours)?
