Modeling and Performance Analysis of Collaborative Workflow System Based on Extended Colored Stochastic Petri Nets

摘要

Based on the Extended Colored Stochastic Petri Nets (ECSPN), the workflow system was modeled and simulated. To improve described capacity of the traditional Petri nets, a model of the extended colored stochastic Petri nets is proposed, and then an instance is given to explain how to model workflow system with priority queuing and multi-instances. Through analysis of the simulation data of the model, a solution to improve the optimal resources allocation and priority services is proposed. Furthermore, it also puts forward a new idea to solve and analyze the workflow performance and resource allocation for a project-based organization.
