IUP Modeling Method and Its Application for Complex Information Systems

An integrated modeling method was proposed based on IDEF, UML and Petri net (IUP). The IDEF model would be established by IDEF0, IDEF1x and IDEF3. By the mapping rule, the UML model would be transformed from the IDEF model for object-oriented software design. The key processes of the IDEF model and the UML model would be transformed into Petri net to analyze the effectiveness and modify models. For the model transformation could be easier, the mapping rule among IDEF, UML and Petri net was studied in this paper. With this method, a model was designed for a spare part management system in a larger metallurgical company, which is configurable, extensible and reusable.
