At the campus copy shop, six jobs have a rrived in the order shown (A, B, C, D, E, and F) at the beginning of the day (today, which is a workday). All of the jobs are due at varioustimes today. Your task is to evaluate four common sequencing rules. 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) time, average lateness, and average number of jobs in the system.c) For the EDD sequence, compute the average completion (flow) time, average lateness, and average number of jobs in the system.d) For the SPT sequence, compute the average completion (flow) time, average lateness, and average number of jobs in the system. e) For the LPT sequence, compute the average completion (flow)time, average lateness, and average number of jobs…
Mike’s Auto Body Shop has five cars waiting to be repaired. The shop is quite small, so only one car can be repaired at a time. The number of days required to repair each car and the promised date for each are given in the following table. (given)
Mike has agreed to provide a rental car to each customer whose car is not repaired on time. Compare the performance of the four sequencing rules FCFS, SPT, EDD, and CR relative to minimizing average tardiness.
In a few words, explain how to prevent a process getting starved in priority scheduling.

- A B1 B2 B3 C1 C2 C3 D1 D2 D3 E A service process is described by the above flowchart. After going through workstation A, an order needs to be processed by one of the three lines, B1-C1-D1, B2-C2-D2, or B3-C3-D3 (in other words, they are substitutable). Finally, all orders need to go through workstation E. The capacities of the individual workstations are given as follows: Workstation A has a capacity of 3 orders/hour • Workstation B1, B2, and B3 have the same capacity of 4 orders/hour • Workstation C1, C2, and C3 have the same capacity of 3 orders/hour • Workstation D1, D2, and D3 have the same capacity of 4 orders/hour • Workstation E has a capacity of 6 orders/hour What is process time of this service process in minutes?arrow_forwardThe first five columns of the following table contain information about a set of four jobs that just arrived (end of Hour 0 or beginning of Hour 1) at an engine lathe. They are the only ones now waiting to be processed. Several operations, including the one at the engine lathe, remain to be done on each job. Determine the schedule by using (a) the CR rule and (b) the S/RO rule. Compare these schedules to those generated by FCFS, SPT, and EDD.

- 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…arrow_forwardI need a b c pleasearrow_forwardplease answer in 30 minutes. answer only if you are 100% sure of solution, else negative rating.arrow_forward
