Interaction simulate method in business process simulation

How to apply Web achievements to the Business Process Simulation (BPS) to compensate for the deficiencies of existing simulation technology and improve the ability of BPS is facing a major problem. Based on simulation technology development trend, this article proposed a BPS platform which is service-oriented and SAAS-based. With this platform, the BPS as a web service on the Internet that provides simulation services for tenants to customize simulation service. This paper put forward to two kinds of simulation methods for simulation engine: User-Instance Simulation and Process-Instance Simulation, and propose a superposition of two kinds of simulation methods called Interaction Simulation method (ISM), this simulation method horizontal and vertical viewing angle of a Business Process execution makes the simulation results more realistic and credible. Based on this method we propose a set of complete simulation model derived from the process definition model. Finally, we design and implement a prototype system.
