Which of the following is a typical objective of scheduling in an operations system?

A typical scheduling objective is to meet due dates while minimising work-in-process inventory, job waiting time and idle time of resources. Maximising idle time, increasing set-up times or deliberately delaying jobs would raise cost and harm delivery performance, so they are not objectives.

  1. AMaximising idle time of machines to keep reserve capacity
  2. BMinimising work-in-process inventory and job waiting time while meeting due datesCorrect
  3. CIncreasing set-up times to improve flexibility
  4. DDelaying all jobs until the due date has passed

Explanation

Scheduling aims to meet delivery dates, reduce flow time, WIP and idle time, and use resources well. The other options describe outcomes that raise cost or cause delay, so they are not objectives.
