This study extends the previous research on priority rules by investigating the effect of due date, processing time, and load variation on the pei (drmance of some well used priority rules in a Job shop environment. Furthermore, tliis study will analyze the performance of the rules under the due window approach. The performance of the rules will be measured in terms of two regular criteria: mean flow time and mean tardiness. In addition, with the incieasing emphasis on using non regular measures, we further study the performance of the rules with respect to the mean absolute deviation (MAD) criterion. Finally, we propose two new rules that perform quiet effectively for the MAD criterion.xvi, 129 leavesEnglishinfo:eu-repo/semantics/openAccessJob Shop SchedulingMADDue WindowPriority rulesTS157.5 .L45 1997Scheduling (Management)--Mathematical models.Job shops.Production scheduling.Thesis
