Explanation of Solution

The logic here is so simple. Supposing that the flow time need to be minimized then the SPT need to be implemented. The advantage of the SPT here is that it minimizes the average job flow time and WIP inventory and also thereby maximizes the resource allocation.

On the other hand, the EDD rule minimizes the average tardiness and lateness and in that it does the best job.

Once the data of processing time, the due date of the single machine are accomplished and the tardiness can easily be minimized, the firm does the best.

	Average	25.00		9.50	11.25

Average Flow Time will be;

=7+10+15+17+23+32+46+508=2008=25.00

The average lateness will be;

=−14+3+7+12+6+16+8+388=768=9.50

The average tardiness will be;

=0+3+7+12+6+16+8+388=908=11.25

Concept Introduction: The process of planning the ordering of the activities involves based on the elements such as, priority, set up time and such other is referred to as sequencing.

C

Expert Solution

Explanation of Solution

The logic here is so simple. Supposing that the flow time need to be minimized then the SPT need to be implemented. The advantage of the SPT here is that it minimizes the average job flow time and WIP inventory and also thereby maximizes the resource allocation.

On the other hand, the EDD rule minimizes the average tardiness and lateness and in that it does the best job.

Once the data of processing time, the due date of the single machine are accomplished and the tardiness can easily be minimized, the firm does the best.
