Abstract
The increased use of flexible manufacturing systems to efficiently provide customers
with diversified products has created a significant set of operational challenges for
managers. This technology is not only becoming more complex to control, but also
presents a number of decision problems. Many issues concerning long-run utilizations
and operational policies are still unresolved.
The primary objective of this study is to examine the effects of aggregation and
disaggregation task allocation approaches of random flexible routings on the performance
of flexible manufacturing systems (FMS) and to analyze the effect of routing
and sequencing flexibility on FMS and their interactions with other factors. The
other experimental factors considered are machine load, alternative processing time
ratio, local buffer capacities, set-up time, machine breakdown, processing time variation
and scheduling rules. For this purpose, a simulation study is conducted and
its results are analyzed by statistical methods.
