Modeling the CAD-CAE Collaborative Process Using Colored Petri Nets

Abstract

With the development of the technology of workflow management, the way of working in companies has been changed a lot. However, the traditional technology of workflow could only deal with the same type of instances. Aiming at solving the problem of collaborative work when there are multi-tasks between cross-departments, we propose an approach of modeling the task distribution process between cross-departments based on colored Petri nets. Firstly, the concept of colored Petri nets and some related characteristics are discussed. Then this method is applied to model the distribution process of CAD-CAE collaborative task. A model of CAD-CAE collaboration is given. Finally, the deadlock of the model is found and the solution is proposed.
