Abstract

Abstract: To keep the atomicity and consistency when complex heterogeneous and loosely coupled Web composition transaction failed，a structured composition compensation and refinement method based on paired Petri-net is proposed.The method solves the problem of abstract modeling in complex multi-partnership business process.Firstly，four basic composition compensation structures are defined on the basis of paired Petri-net，such as sequence，parallel，alternative and iteration.Secondly，the concept of composition process refinement is introduced and the proof of some related qualities after refinement is presented.The feasibility of this method is proved by a case study.

Key words: Web services composition, paired Petri-net, structured composition compensation, process refinement qualities

摘要： 针对复杂异构、松耦合Web组合事务执行失败时原子性和一致性保持的问题，提出一种基于配对Petri网的复杂组合业务流程的补偿和精化方法，解决复杂多伙伴业务流程的抽象建模问题。首先定义了4种基于配对Petri网的基本组合补偿结构：顺序、并行、选择和迭代结构；然后引入组合流程精化的概念，给出了精化后相关性质的证明，最后通过具体业务实例验证该精化方法的可行性。
