Abstract

A Petri net modeling tool using the object oriented method is introduced in this paper. With this tool, a Petri net-based prototype of fault diagnosis was developed using the model-based method. The prototype was connected to the database by DAO technique, and the firing mechanism and analytic methods of Petri net were used to form the DLL documents. Compared with the method of rule-based expert system, the Petri net-based one has the following advantages: 1) with direct knowledge representation; 2) with convenient knowledge storage in a form of mathematical matrix; and 3) making inference more quickly and effectively
