摘要
Web服务组合的正确性验证对提高软件开发效率、实现服务增值具有重要意义。为从高层抽象层次研究Web服务组合的正确性及其形式化验证方法,考虑到Web服务组合中的实时特征,在采用软件体系结构描述语言XYZ/ADL对Web服务组合进行描述的基础上,将其实时描述部分XYZ/RE转换至时间自动机模型,组合后系统应满足的性质用分支时序逻辑CTL公式表示,最后应用模型检测工具UPPAAL实现了Web服务组合正确性的自动化验证。
Correctness verification of Web service composition plays an important role for improving software development efficiency and realizing service value-added.To study the correctness of Web service composition and their formal verification method from a high and abstract view,considering the real-time feature in Web service composition,based on the description of Web service composition using software architecture description language XYZ/ADL,the real-time description XYZ/RE was transformed to timed automata,the properties that the composite system should be satisfied were expressed in CTL formula,last,the correctness of Web service composition was automatically verified through a model checking tool—UPPAAL.
