Modeling and Simulation of Web Services Composition Based on MARDS Model.

Web services composition is an emerging paradigm for application integration within and across organizations and enterprises. A set of languages and techniques for web services composition has emerged and is continuously being enriched with new proposals from different vendors. Among these languages we remind Business Process Execution Language (BPEL) which emphasizes the importance of modelling and simulating of business process in Web Services composition. Multi-agent Systems (MAS) are composed of autonomous agents that interact and coordinate to achieve their intentions. This makes them particularly adapted to modelling composite and complex information systems. In this paper we propose a new approach for modeling and simulating the process of web services composition using the Multi-Agent Reactive Decisional System (MARDS) Model and BPEL Language.
