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.

Students have asked these similar questions

Diablo Electronics manufactures four unique products (A, B, C, and D) that are fabricated and assembledin five different workstations (V, W, X, Y, and Z) using a small batch process. Each workstation is staffedby a worker who is dedicated to work a single shift per day at an assigned workstation. Batch setuptimes have been reduced to such an extent that they can be considered negligible. A flowchart denotesthe path each product follows through the manufacturing process as shown in Figure 5.2, where eachproduct’s price, demand per week, and processing times per unit are indicated as well. Inverted trianglesrepresent purchased parts and raw materials consumed per unit at different workstations. Diablo canmake and sell up to the limit of its demand per week, and no penalties are incurred for not being able tomeet all the demand.Which of the five workstations (V, W, X, Y, or Z) has the highest utilization, and thus serves as the bottle-neck for Diablo Electronics?

What are the advantages and disadvantages of the shortest processing time (SPT) rule?

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.
