Quizplus · Accepted Answer

Using the SPT rule, Jack will schedule Job 1 first with a processing time of 2 hours. Then, he will schedule Job 2 with a processing time of 3 hours, and finally, he will schedule Job 3 with a processing time of 4 hours.

The average WIP can be calculated by adding up the processing times of all jobs and dividing by the total number of jobs.

(2+3+4)/3 = 3

Therefore, the average WIP in Jack's shop today is 3 jobs.

The best choice is B as it is the closest option to the calculated result of 3.
