Question: a . Mean Flow Time: Mean flow time represents the average duration a job spends in the system from start to finish. It is calculated

a. Mean Flow Time:
Mean flow time represents the average duration a job spends in the system from start to finish. It is calculated by summing up the processing times of all jobs and dividing by the total number of jobs.
The first-come, first-served (FCFS) sequence minimizes mean flow time by prioritizing jobs in the order they arrive.
b. Maximum Lateness:
Maximum lateness refers to the longest delay among all jobs in completing their tasks.
The shortest processing time (SPT) sequence minimizes maximum lateness by prioritizing jobs with the shortest processing times first.
c. Number of Tardy Jobs:
The number of tardy jobs indicates the count of jobs that are completed after their promised dates.
