Abstract :
This paper proposes a new method for modeling the real-time service components composition using DCValid, an interval temporal logic. We first introduce the definition of service component formalism. Then we analyze how to use DCValid to describe the components composition in detail. Moreover, the temporal constraint checking of components composition is discussed. The main characteristic of our method is that it can formally depict the temporal constraints with different granularities of the service-oriented system.
