跨组织多业务事务建模与验证方法

Modeling and Verification of Cross-Organizational Multi-Business Transactions

面向服务的事务处理是保障业务交互和协作正确性的关键技术.针对跨组织多业务流程,提供了一种支持多业务事务建模与验证的方法.在建模方法上,对Pi-演算扩展了事务语义,将进程间的动作交互与跨组织膜活动相关联来刻画多业务事务协调行为.在验证过程中,基于等价自动机转换思路集成现有模型检验技术,验证多业务事务是否满足人们需要的各种性质.实验结果表明,该建模与验证方法能够有效地保障多业务流程在设计与实现过程中的正确性.

Service-Oriented transaction processing is a key technology to ensure the correctness of interaction and collaboration among business processes. For cross-organizational multi-business processes, an approach of modeling and verification of multi-business transactions is proposed in this paper. In the modeling approach, an extended Pi-calculus was proposed to describe business transactions coordination via introducing transaction semantics based on the connection between the process interactions and transaction membrane activities. On the other hand, the model checker is employed for checking whether or not the multi-business transactions satisfy the given properties by equal value transformation of the finite state automaton. Finally, the experimental results have demonstrated that it is an important means of ensuring correctness during the design and implementation of multi-business processes.
