The effect of control-decision systems towards the performance parameters of FMS

摘要

Flexible Manufacturing Systems (FMS) are highly complicated systems that possess high flexibility in their operation. FMS is basically used for the batch production process. Due to such complex nature of FMS the shop floor control in such systems becomes quite a challenging task. It really becomes difficult to implement an appropriate scheduling and dispatching rule for proper shop floor control. Hence, there is a need of a decision-making process for effective control of FMS. The decision-making system consists of varieties of task like a collection of shop floor data, appealing the decision-making activity, evaluation of available alternatives and finally the execution of the best alternative. This paper deals with the various types of the decision-making approaches that can be outlined for the shop floor control of the FMS. A real-time FMS problem is taken and those approaches are implemented in it and finally the simulation of the results is done using ARENA software. The various situations based on the approaches are also outlined in the study and its effect on the results are studied. A graphical interpretation is finally done for the results.
