Question

Quizplus · Accepted Answer

The average completion time for a schedule sequence at a work center is the total flow time (the time a job spends in the system, including both waiting and processing time) divided by the number of jobs. Option C matches this definition while the other options do not. A represents the average processing time per job. B represents the ratio of the total time in the system to the processing time, but does not take into account the number of jobs. D represents the ratio of processing and late time to the number of jobs, which is not equivalent to the average completion time. E is the ratio of total time in the system plus late time to the number of jobs, which is also not equivalent to the average completion time.
