Abstract

In the context of supervisory control of discrete-event systems, decentralized control is a well-established area of research. In this paper we present an implementation of such controllers for an assembly cell with two-assembly stations (SCARA robots), in a laboratory scale Computer Integrated manufacturing (CIM) system. Step by step implementation, conflict avoidance between local supervisors and difficulties encountered are discussed. Petri nets are used as the modelling tool and Lin and Wonham [7] framework is used as the control architecture. Assembly stations are modelled as intelligent agents. A separate software module called Order Processing Module (OPM) is used to handle orders into and out of the system and to schedule the two-assembly stations.
