Abstract:
Web service composition is studied by many works, and constitutes the heart of a great research activity. However, the majority of this work does not take into account all temporal constraints imposed by the service provider and the users in the composition process. Incorporating temporal constraints in Web service composition result in more complex model and make crucial the verification of temporal consistence during the modeling (at design time) and then during the execution (at run time). In this paper, we presented H-Service-Net model for Web service composition with time constraints, and propose a modular approach for modeling composition with time constraint using Extend time unit system (XTUS), Allen’s interval algebra and comparison operators in a time Petri net model.
