A flexible simulation framework for evaluating multi-level, heuristic-based production control strategies

A flexible simulation framework (FSF) is described which greatly reduces changeover time between scenarios and allows the rapid examination of multiple heuristic alternatives. The effectiveness of the framework is tested in the development phase of a heuristic-based, three-level FCS (flexible control strategy). The production basis for this experimentation is a mixed technology printed circuit board assembly plant. The performance of the flexible framework is discussed with a focus on the advantages and limitations of the approach in this challenging environment. Through the inclusion of specific interfacing mechanisms between control subroutines, and through standardization of inputs and outputs to those subroutines, the FSF helps to isolate operational control problems and helps to minimize the management task associated with operational flexibility. This feature is especially important as additional operational flexibility is made available
