Low machine commonality High Machine Commonality OOM WINQ OOM WINQ 3 AGV 42.
Results show there are significant differences in mean time in system for a given sequencing rule depending on whether OOM or WINQ is employed to assign machines.
The major surprise of the results is the superior performance of WINQ when compared to OOM.
The analysis of the average machine utilization controlled for assignment rule, number of AGVs, and machine commonality shows that for every treatment combination, the WINQ maximum machine utilization were lower than those generated by OOM.
It was found that the lowest time in system was provided by the configuration in which parts were assigned to machines using the WINQ rule at the high level of machine commonality and five vehicles used to move parts among machines.
