Detecting Feature Interactions in Web Services with Timed Automata
Xiangyu Luo, Aicheng Xuan, Rongsheng Dong · 2009
With the rapid development of Web services, feature interactions have become one of the critical problems in Web services composition. This paper proposes a model checking method for detecting feature interactions in Web services composition. By the proposed method, the Web services descriptions written in WS-BPEL are translated into timed automata, and then we apply a well known model checking tool UPPAAL that supports this formalism to modeling Web services composition and analyzing feature interactions. We take a particular case study, an automatic stock trading system, as an example to illustrate the effectiveness of the proposed method.
