Sabuncuoğlu, İ.Kızılışık, Ö.

Specifically, we develop a simulationbased scheduling system for flexible manufacturing systems. We also propose several reactive scheduling policies (i.e. when-to-schedule and how-to-schedule policies) and test their performances under various experimental conditions, processing time variations, and machine breakdowns. Moreover, we compare offline and online scheduling schemes in a dynamic manufacturing environment. The results of extensive simulation experiments indicate that the variable-timeresponse is better than the fixed-time-response. The full scheduling scheme generally performs better than the partial scheduling. Finally, the online scheduling is more robust to uncertainty and variations in processing times than the optimumseeking offline scheduling. A comprehensive bibliography is also provided in the paper.EnglishComputer simulationDecision makingOnline systemsResource allocationSchedulingTime and motion studyMachine breakdownsReactive scheduling problemFlexible manufacturing systemsArticle10.1080/00207540310001492021366-588X
