M. Thirumaran, M. Jannani

Web services combine the best aspects of component-based development and the Web. With the increase in the demand for incorporating dynamic changes to services in long term composition, Web service change management has gained a lot of attention. Though a lot of works have focused on providing an optimized solution for dynamic changes only a very few have concentrated on the methodology adopted. In this paper, we focus on providing a formal approach for the evaluation of the changes made. The verification of order of execution in Long term Composed Services (LCS) has been performed using Finite State Machine and has been elucidated using Passport system as the case study.
