Today's manufacturing environment involves great flexibility and fast change over in manufacturing systems. Development of control model and system for production has long been interested by researchers. Presented in the paper is a systematic approach to constructing a Petri-net model of production system and method for design a graphical model of a FMS(Flexible Manufacturing System) by using a new modeling tool which is called JR-net (Job Resource-relation net).A functional JR-net model is a directed graph in which the standard resources of FMS become nodes and job transfers among the resources become the arcs of the graph. The usefulness of the proposed JR-net modeling framework is demonstrated in terms of ease of model building, modeling power and ease of communication in the modeling of FMS. So, the procedure of modeling in the FMS is the same as current practice of FMS design and is based on the IOM (Integrated Object-oriented Modeling) paradigm.Finally, the implementation issues of JR-net modeling are addressed. The approach is the IOM from JR-net modeling by Petri-net and the other is a development of IOM tool for FMS.
