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 5a. A Chef bakes and decorates cakes in a two-stage process. The cakes are baked and once cooledthey are then decorated based on the clients’ requirements. The Chef received seven orders forfully decorated cakes and has documented the orders with respective processing times for bakingand decorating, as shown in Table 7 that follows:.Table 7.

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_forward
