Concept explainers
a)
To determine: Thesequence of jobs that are based on decision rule First Come First Served (FCFS).
Introduction: First Come First Served is the
b)
To determine: The sequence of jobs based on decision rule Shortest Processing Time (SPT).
Introduction: Shortest Processing Tine is the scheduling rule, which helps to arrange the sequence in the order. Here, job with the shortest duration would be served first. Then, the process would go on from the shortest to largest duration.
c)
To determine: The sequence of jobs based on decision rule Longest Processing Time (LPT).
Introduction: Largest Processing Tine is the scheduling rule, which helps to arrange the sequence in the order. Here, job with the largest duration would be served first. Then, the process would go on from the largest to shortest duration.
d)
To determine: The sequence of jobs based on decision rule Earliest Due Date (EDD).
Introduction: Earliest Due Date is the scheduling rule, which helps to arrange the sequence in the order. Here, job with the earliest due date would be served first. Then, the process would go on from the earliest due date to latest due date.
e)
To determine: The sequence of jobs based on critical ratio.
Introduction: Critical ratio is kind of scheduling rule that helps to identify that, the task or job is on the correct track. It would help to identify if the task is behind or ahead of the schedule.

- QUESTION 6 The framing department has six jobs waiting to be processed as shown in Table 3 below. It is now time zero and all jobs are ready to begin. Each has only one operation remaining. Table 3 Jobs (In order of arrival) Processing Time Due Date A 5 12 B 7 18 C 8. 14 D 3 10 E 9 22 F 12 17 Using minimum flow time as the evaluation criterion, recommend the best rule to sequence the jobs from the list below: i. FCFS ii. SOT iii. EDD iv. STRarrow_forwardQuestion 4: Six jobs waiting at a workstation will be processed in order, starting with the one with the shortest break time. In the table below, the time elapsed since the arrival of the works, the time remaining to the delivery and the processing time are given. According to this, create the work order and fill in the data in the relevant table.(fill in the second table in the photos)a) What is the average delay time with the generated order?b) How many hours is the average flow time?c) How many jobs will be delayed?d) How many jobs will not be delayed?arrow_forwardQuestion 1) Scheduling If the following jobs are sequenced according to the FCFS rule Job Processing Time (days) Due Date A 8 12 B 6 15 C 11 17 D 5 10 E 3 8 What is the mean tardiness (in days) for all jobs? What is the mean completion time in days for all jobs? What is the maximum job tardiness (in days)arrow_forward
