Question
(a) Shortest Processing Time minimizes the flow time of jobs at a resource because it reduces the processing times of the jobs. A. True B. False (b) Which of the following statements best explains why an organization would use Weighted Shortest Processing Time (WSPT) instead of Shortest Processing Time (SPT)? A. Jobs differ in how important it is for them to be completed quickly. B. They want to minimize the average flow time across all jobs. C. WSPT is a simple rule to implement as jobs are processed in the order they arrive. D. They want to minimize the average number of jobs in the system waiting to be processed.Explanation / Answer
a. The answer is False. Shortest Processing Time does not minimize the flow time of jobs at a resource because it reduces the processing time of jobs, it only sequences the jobs from shortest processing times to largest processing times.
b. The answer is A. Because Weighted Shortest Processing Time focuses on the processing time of jobs per unit of importance. The rule of WSPT itself focuses on importance of the job.
