Concept explainers
a)
To determine: Thesequence of jobs based on the decision rule, i.e, First Come First Served (FCFS).
Introduction: The First Come First Served is the
b)
To determine: The sequence of jobs based on the decision rule, i.e, Earliest Due Date (EDD).
Introduction: The Earliest Due Date is the scheduling rule, which helps to arrange the sequence in the order. Here, the job with the earliest due date would be served first. Then, the process would be go on from the earliest due date to the latest due date.
c)
To determine: The sequence of jobs based on the decision rule, i.e, Shortest Processing Time (SPT).
Introduction: The Shortest Processing Time is the scheduling rule, which helps to arrange the sequence in the order. Here, the job with the shortest duration is served first. Then, the process would be go on from the shortest to the largest duration.
d)
To determine: The sequence of jobs based on the decision rule, i.e, Longest Processing Time (LPT).
Introduction: The Largest Processing Tine is the scheduling rule, which helps to arrange the sequence in the order. Here, the job with the largest duration is served first. Then, the process would go on from the largest to the shortest duration.

- Question Three Processing times (including setup times), and due dates for five jobs waiting to be processed at a work center are given in the following table. By Using the SPT rule determine the following: The sequence of jobs The average flow time The average job tardiness The average number of jobs at the work center Job Processing Time (hours) Hour Due A 17 15 B 10 25 C 5 20 D 7 32 E 11 38arrow_forwardQuestion 35 Consider the processing times and due dates of the following jobs: Job Processing time (days) Due date (days) 1 3 29 2 19 25 3 24 40 4 8 20 What is the average lateness if the earliest due date (EDD) is used to sequence the jobs? Group of answer choices 0.75 1.25 4.25 5.67arrow_forwardQuestion 1 Four floral arranging jobs are to be carried out across three stations: A (Arrange), B (Bag), C (crop) shown. The station sequences and job times in minutes are shown below, along with the due dates for each job. Using an "earliest due date" job dispatching priority rule, which, if any, of the jobs in will be late? Tip: create a Gantt chart schedule before answering Questions 4 & 5. a. Jobs 2 & 3 b. Jobs 3 & 4 c. Job 3 d. Job 4 e. None of the jobs will be latearrow_forward
- Question3: Two processes are applied in the same order to the jobs coming to a workstation. The durations of both processes for the six jobs coming to the workstation are as seen in the table. In order to minimize the total time to be spent on the jobs, the order in which the jobs should be done will be determined by the "johnson" rule. Accordingly, in the table below, write the order in which the business should do the work, in order, with the first things to be done on the far left, and one action to be written in each blank.1-) When the jobs are done in this order, how many minutes will it take to complete all the jobs?2-)1. How many minutes of space will there be in total in the process and the 2nd process?arrow_forwardQuestion:-M Full explain this question and text typing work only.arrow_forwardQuestion fourThree jobs are to be scheduled on two machines A and B. Assume that the jobs are processed in the sequence A-B (A has to finish the job before B can continue the job). The processing times are: Job A B1 5 42 7 73 3 5Draw a Gantt chart that shows the schedule corresponding to the sequence 1-2-3 of the jobs.arrow_forward
- Question Scenario: Early one Monday morning in Jamaica, Susan, a Restaurant Manager starts getting ready for the morning’s work operations. She is particularly happy because tonight he has a date with Marvin, the new Chef that was recently hired. The problem, as Susan sees it, is that Roberta, another Restaurant employee has been just a little too friendly with Marvin lately and that really upsets Susan.

However, that plan doesn’t seem to be working. Despite a lighter pay cheque and frequent reprimand through the disciplinary process of creating reasons to write to her about her conduct and performance. Roberta has decided to quit her studies due to her inability to fund her tuition. A few days later, Susan noticed Marvin and Roberta having lunch together in the staff dining room. Susan got furious…arrow_forwardQuestion 32 The processing times of four jobs are given as follows: Job Processing time (minutes) A 10 B 30 C 16 D 24 Assume the jobs arrived in alphabetical order of the job name and no other job arrives in the next 70 minutes. What is the average flow time in minutes if the jobs are processed in shortest processing time (SOP) order?
