Research on workflow model based on Hierarchical Coloured Petri Nets

In this paper, the office supplies application process model based on Hierarchical Coloured Petri Nets(HCPN) is built. The CPN Tools is a tool which for modeling, simulation and analysis CPN. This model is build with CPN Tools, the model and its performance is simulated and analyzed. The Extend Resource Petri Nets (ERPN) is presented to build a new optimized model. In the end, a combination method of Genetic Algorithm(GA) and coloured Petri nets is presented to further optimize the model, the optimized results prove this method is feasible and effective.
