Question

Processing times and due dates for five jobs... Processing times and due dates for five jobs are shown in the table below. Assume the jobs are processed using the earliest-due-date rule. Job Processing time (weeks) Due time (weeks) A B 1 1.02 8 2 WP> D E 5 1.0 1 4 8 12. What would be the lateness of job B? weeks weeks 13. What would be the tardiness of job E? This is a numeric cell, so please enter numbers only. 14. What is the maximum tardiness for this set of jobs?

Answer 1

The lateness of job B is 0 weeks and the tardiness of job E is -4 weeks. The maximum tardiness for this set of jobs is 0 weeks.

Step-by-step explanation:

To find the lateness of job B, we need to calculate the difference between its completion time and its due time. The processing time of job B is 1 week and its due time is 2 weeks. Since job B is processed using the earliest-due-date rule, it is completed on time. Therefore, the lateness of job B is 0 weeks.

To find the tardiness of job E, we need to calculate the difference between its completion time and its due time. The processing time of job E is 4 weeks and its due time is 12 weeks. Since job E is completed in 8 weeks, it is early and has a tardiness of -4 weeks.

The maximum tardiness for this set of jobs is the maximum amount of time a job is late. In this case, the maximum tardiness is 0 weeks because job B is completed on time.
