面向环境层的服务组合方法

Service Composition Method Oriented on Environment Level

自动服务组合是实现云计算按需服务的关键技术与研究热点。然而,当前理论和工具无法支撑服务组合的开放性、动态性以及复杂性等特征。基于环境建模的思想,提出了一种划分问题,改变问题性质的方法和面向环境的服务组合框架,并给出了组合算法。为解决服务组合问题的复杂性和当前理论和工具的局限性之间的矛盾提供了新的途径,为开发新的服务组合方法提供了基础。

Automatic service composition is a hot research topic and key technology in cloud computing. Because the service composition is open,dynamic and high complexity,few tools or theories can challenge it. Based on the ideas of environment modeling,we proposed a method to divide and adapt the problem and the composition framework on environment level. Furthermore,the related algorithms were presented. This method can help to bridge the gap between the existing theory or tools and the problem of service composition,and provide a foundation for the development of the new service composition method.
