Abstract: Enterprise managers can do strategic readjust in time, such as readjusting resource, and improve the success rate of workflow execution eventually according to the prediction for the success of workflow execution at runtime. By analyzing what roles different constraints play in model and execution level respectively, the impact of constraint satisfaction factors on success of workflow execution were found out. Based on the correlation of constrations and time dependency of constraint satisfaction, an approach to identify the validity of workflow execution path was proposed, as well as its algorithms was also presented. Finally, qualitative analysis provided by a practical case shows the feasibility of this approach.
