To determine: Thejob sequence, flow time, utilization metric, average number of jobs, and average lateness for EDD, SPT, LPT, and FCFS.
Introduction:
b)
To determine: The dispatching rule that has the best score in flow time.
Introduction: Scheduling is the process of controlling and arranging the workloads of the production process using the optimized way. It is used to plan on allocating human resources and machinery.

The station sequences and job times in minutes are shown below, along with the due dates for each job. Using an "earliest due date" job dispatching priority rule, which, if any, of the jobs in will be late?
