Which Priority Rules are used for Job Sequencing?

Kamauf Custom Glass, Inc., manufactures custom windows primarily for homes and churches. Small repair jobsmay take a few hours, but larger jobs may take hundreds ofhours. How to schedule the jobs is a continuing issue. The schedulerhas decided to see what insight can be gained by examiningsome common sequencing rules, namely FCFS, EDD, SPT, andLPT, on the criteria of average completion (flow) time, averagelateness, and average number of jobs in the system. Her sampleis the six jobs on the scheduler's desk Monday morning. Assumethat all jobs on the scheduler's desk arrived today (day 100, whichis a workday) in the order shown below. The estimated times tocomplete the jobs and their due dates are noted.                                                                                            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) t ime, average lateness, and average number of…
