A hierarchical modeling methodology for flexible manufacturing systems using extended Petri nets

Abstract

A theory of extended Petri nets is proposed to enable the modeling of flexible manufacturing systems in a more comprehensive manner. The theory considers both the flow of control and flow of information, resources and parts in a system. A methodology for hierarchically modeling manufacturing systems using extended Petri net techniques, to ensure a priori the desirable properties of system performance is presented. The approach is based on modular modeling.<>
