Abstract—State space explosion is one of the biggest problem in model checking. Predicate abstraction technique is used to reduce the size of state space of colored Petri net models, and an algorithm was proposed to obtain the abstracted state space of a colored Petri net model without its original state space generated. A method to verify safety properties of Web service composition by abstracted state space and the Counterexample-Guided Abstraction Refinement was proposed. The problem of state space explosion is solved to some extend by this way. Finally, with an example, an application of this method is illustrated, which its efficiency shown.
