Sequencing: The Shortest Processing Time Rule
- 2.7k Downloads
The problem of sequencing arises frequently in many areas of business and engineering. Shortest-first sequencing (or one of its variants) has proven to be optimal in a number of problem areas.
Thanks to a day's exposure at the annual professional conference, Alison has received four requests for design work. Based on her experience, she can estimate how long it would take her to deliver each design, noting that some of the jobs were short ones and others were longer. In addition, Alison's working style is to focus on one job at a time, postponing any thought about the others until the current one is finished. Nevertheless, as she thinks about the situation, she realizes that her four customers will get different impressions of her responsiveness depending on the order in which she completes the designs. In other words, it seems to make a difference what sequence she chooses for the jobs.
