近年来，随着以服务为导向的框架技术的产生和发展，web服务技术已经获得了信息技术社区和商业社会的广泛关注和研究。Web服务是一种跟传统面向对象开发模式所不一样的新型模块化开发模式，具有面向功能的更高抽象粒度。但是，随着web服务数量的逐渐增多，单一功能的Web服务面临着难以满足用户复杂多变的实时需求。在很多场景下必须把单一功能的Web服务整合成具有更复杂功能的复合Web服务。因此，人们提出很多优化算法来解决基于Qos属性的Web服务组合问题。该文针对以上Web服务组合问题，引入一种新型的基于群体智能的优化算法来解决Web服务组合问题。实验结果表明了改进后的狼群算法跟传统的优化算法相比在效率和性能有一定的提高。

Thanks to the emergence and widespread of Service-oriented Architecture(SOA),Web service technology has got its attention around the Internet Community. However, single simple web service face the challenge of being unable to satisfy users ’ complex requirements in runtime environment as the amounts of web services become larger and larger. Therefore a lot of opti?mization solution has been proposed aimed to address the web service composition issue. Whereas most of them are of low effi?ciency and accuracy. The paper has introduced a new kind of colony intelligent algorithm to address the QoS-based web service composition, which is called Wolf Colony Algorithm. The experimental results show that the WCA outperform in comparison with traditional heuristic algorithm such as particle swarm algorithm.
