Modelling method of dynamic business process based on pi-calculus

The formal modelling for dynamic business process is to make the collaborative relationship between organisations more detailed and explicit. It is convenient for the people to analyse the structure and interaction of the cross-organisational business process, especially dynamic business process, and assure the optimisation of the system architecture. Based on the channel mobility of pi-calculus, a new modelling method of the dynamic business process is proposed by combining with the extended directed acyclic graph. It is mainly discussed from three aspects: the selection of the interactive paths, the transition of business objects and the validation of accuracy. Meanwhile, a concrete example with multiple roles is presented to assist in the implementation of the method. It concludes that the method can effectively distinguish the collaborative relationship between organisations, and also be used to build formal models of complicated and dynamic business processes with the mature technology.
