摘要
The method currently applied to ensure the robustness and dependability of Web Services compositions do not effectively map to more open, dynamic environments. This paper proposed a new multi-layer Web Services composition model based on Multi-Agent Systems and the Choreography model. Every layer of our model provides specific conceptual descriptions and domain capabilities of their domain. We used contract to regulate the Agents behaviors and make Web Services autonomic with Agents' own intelligence. We gave different self-adaptive mechanisms corresponding to different environment's evolutions to improve the reliability of Web Services composition efficiently.
