Web services composition is a key technology to solve cross-organizational business process integrations.However,it is hard to ensure its trusted propertiesaradigm and open Internet ru(including correctnessnning environment. To,reliability solve this,safety proble)m,because of the loosely coupled development pal verification and abstraction method for Web services composition based on model checkin,this paper proposes a formg Multi-Agent Systems(MAS)and refinement. By applying the method of the graph-like counterexample guided abstraction and refinement on MCTK,it greatly reduces the state explosion problem of model checking. The correctness of the method is proved theoretically. Recording to the experimental results of which translates a credit risk assessment Web services to a MAS programmed by input language of MCTK then model checks both abstracted and un-abstracted MAS,the Web services verification based on proposed method works much more efficiently than the normal verification based on MAS model checking.
