Abstract

This research presents a simulation study to investigate the effect of several static and dynamic sequencing rules on the performance of a dynamic pure flow shop. Two levels; medium (80%) and high (90%) of shop utilization are considered. Job due dates are set at two levels of tightness; loose and tight, using the total work content method. The results indicate that the shortest processing time rule and the earliest due date rule are superior to other rules.. Static rules are found more effective and efficient than dynamic rules for ail shop conditions considered. Finally, this study shows that operating policies that perform well in job shops and assembly shops may not work well in pure flow shop environments, and management selection of the right operating policies become more effective in congested with tight due date flow shop conditions.
