With the development of advanced Internet technology, business applications across multiple enterprises based on Web Services Composition (WSC) paradigm are widely used. When system failure occurs, some tasks of the flow may be committed while others unscheduled, in this situation, it is important to accurately analyze execution log of composition business process. In this paper, we formally defines Web services composition compensation based on paired net, and analyze execution logs, dataflow dependency and behavior dependency between tasks in composition process, and discuss the refinement for Web services composition compensation process and the abstract replacement of complex compensation process. The classical composition transaction application Trip Reservation Process (TRP) shows the feasibility of ensuring consistent execution of reliable composition.
