Modelling and simulation of flexible assembly systems A petri net approach

Abstract

This paper presents an approach towards constructing a class of Placc/TYansition nets for modelling, simulation and control of processes occurring in the Flexible Assembly Systems. Its objective lies in the formal statement of the conditions allowing to design the nets consisting of viable discrete control logic models, i.e. nets encompassing admissible control of the processes flow. We consider batch production processes which can be decomposed into a set of transportation and assembly operations. For each operation, required resources arc identified like workpiece buffers and industrial robots. The approach proposed is applied to a decision support system whose design and operation is outlined.
