In order to adapt to the requirements of the business process multi-functional and dynamic change

getting business processes with modular substitution is one of the effective ways to solve these problems.The concept of differential control Petri net and differential data Petri net are proposed based on open Petri net and differential Petri net.Liveness detection in control flow and data flow of models is examined by the evolution expression of differential Petri net through semantics

and stability analysis of substitution module and its discrete and continuous parts are done by differential Petri net

respectively

to achieve business process module adaptation analysis.Theoretical analysis results show that the established model of differential expression can reflect the liveness and stability of models

module adaptation effect is better.Finally

we develop the simulation analysis based on data platform;the experimental results show that the presented method is effective.
