This paper describes a diagramming methodology, referred to as an Object Flow Diagram (OFD), that is intended to be a key component in the conceptual design of a discrete-event simulation model. It provides an effective means for representing salient system elements and their relationships. It draws upon other popular system diagramming methods, such as(More)
Petri nets are used for describing, designing and studying discrete event-driven systems that are characterized as being concurrent, asynchronous, distributed, parallel, and/or nondeterministic. As a graphical tool, Petri net can be used for planning and designing a system with given objectives, more effectively than flowcharts and block diagrams. As a(More)
