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.

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: the following table contains information concerning four jobs that are awaiting processing at a work center. Job Time Due Date Job A (Days) 15 (Days) 21 7 15 16 10 17 a. Sequence the jobs using (1) First come, first served, (2) Shortest processing time, (3) Earliest due date, and (4) Critical ratio. ASsume the list is by order of arrival. b.

Daniel Ball is inter- ested in treating his barbers as well as he can with steady work and preferably 5 days of work with two consecutive days off. His analysis of his staffing needs resulted in the following plan. Schedule Daniel's staff with the minimum number of barbers. DAY MON. TUE. WED. THU. FRI. SAT.

- 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_forwardQuestion3: 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_forwardQUESTIONS: 1. A production department of a textile firm received six different orders this week. They have calculated the processing time presented as a table (below). They have also put the due dates for each job. Job с E B D F Process. Time 2 4 5 8 10 12 Due Date 7 4 15 16 17 18 Based on the table please provide four sequences to complete the jobs: a) Using first come first served (FCFS) assuming the letters represent the order they arrive (A first, B next, then C, etc..) b) Using shortest processing time c) Using longest processing time d) Using due dates Calculate "average completion time", "average number of jobs in the system" and "average job lateness" for all the sequences you have generated above.arrow_forward
