为了保证服务交互行为与其定义的关键属性相一致,本文提出了一种基于有色Petri网模型的运行时确保机制,从而提高服务组合运行的可靠性.文章首先介绍了服务交互行为CPN模型,用于精确刻画服务交互行为及其重要属性.结合服务实例,进一步对模型可达集和关键监控属性展开深入分析.在可达集的基础上,描述将模型运用于运行时监控的方式确保服务交互行为的关键属性.同时,本文从并行化执行流程和交互行为检测算法两方面介绍了服务交互行为的运行时监控机制.最后,评测结果表明这种运行时确保机制在性能、检测效率等方面都具有良好的表现.%To assure the accordance of services interactive behaviors and defined critical properties, this paper provides a CPN based runtime assurance mechanism. A service interactive behaviors CPN model is introduced to analyze reachability sets and critical iproperties of a composed service sample. It also depicts the mechanism on how to rumtime monitoring these properties. At the end, evaluations show that this runtime assurance mechanism has very good performance and efficiency.
