CPIM Practice Exam

In which scheduling method are jobs completed based on their earliest end unit due date?

1. First come, first served (FCFS)

2. Shortest process time (SPT)

3. Earliest job due date (EDD)

4. Critical ratio (CR)

The correct answer is: Earliest job due date (EDD)

The scheduling method that focuses on completing jobs based on their earliest end unit due date is indeed the one that prioritizes tasks according to their deadlines. In this method, jobs are arranged in order of their due dates so that the ones that are due first are completed ahead of others. This approach helps to minimize the likelihood of jobs missing their deadlines, making it particularly useful in environments where timely completion is critical. This method can be very effective in managing work to meet customer expectations and ensuring that resources are allocated efficiently to prevent delays. By prioritizing jobs based on their due dates, it helps to enhance overall workflow and supports the smooth operation of the entire scheduling process. In contrast, other methods like First Come, First Served (FCFS) simply process jobs in the order they arrive without regard to due dates, while Shortest Process Time (SPT) focuses solely on the duration needed to complete the tasks, ignoring their deadlines. The Critical Ratio method evaluates jobs based on the ratio of time remaining until due date to the processing time left, which may not directly adhere to the principle of focusing strictly on the earliest due date.
