Integrating UML and GPSS for Business Process Modeling and Simulation
Simulation is a dynamic modeling technology. However there is little integration of business process static modeling and simulation, which prevents simulation from becoming a mainstream modeling method/tool. Firstly, UML activity diagram is extended using UML extensibility mechanism for BPS, which enhances activity diagram's ability of describing business process and adds some information which the simulation needs. Secondly, the principles and methods that can be used to translate extended UML activity diagram into the GPSS model are proposed, which realizes the integration of the static model and the dynamic model. Finally, a supporting software tool system of integrating UML and GPSS for business process modeling and simulation has been developed based on the authors' proposed methods.
