(a)
Interpretation:
The time that is required to complete all the five cars if the cars are processed in alphabetical order.
Concept Introduction:
The operation manager have to
(b)
Interpretation:
The sequence in which the cars should be processed to minimize the make span of the schedule and how long will that be.
Concept Introduction:
In order to minimize the makespan of the schedule, the sequence of SPT is to be followed. In other words, the schedule of the car that has the shortest processing time first, and this is followed by the next that has the shortest processing time and so on.
(c)
Interpretation:
The flow time of each car as per the schedule found in part b.
Concept Introduction:
In order to minimize the makespan of the schedule, the sequence of SPT is to be followed. In other words, the schedule of the car that has the shortest processing time first, and this is followed by the next that has the shortest processing time and so on.

- The company has obtained a new contract to finish up some apartments that had been constructed by another firm whose contract has since been terminated by the building consortium that hired it. There are six apartments. DeLaw Construction Limited has the contract to first electrically wire each apartment and to then paint them. Wiring must be completed before painting and the company can only work on one apartment at a time. Determine the optimal sequence in which DeLaw Construction should do each apartment. Provide a time line for the sequence as well. The table below shows how much time each apartment is estimated to require for both wiring and painting, in days. Each apartment is denoted by the area it is located in.
