摘　　要：WebServices合成是WebServices技术的重要方面,能够按要求提供选择新的服务。本文首先提出了WebServices服务约束的分类描述,进而分析了WebServices服务合成中如何按照服务约束指导服务选择,进而选择合适的服务集来满足客户的要求。该方法把动态WebServices合成转化为约束满足问题。Web Services composition is a crucial aspect of Web services technology, which gives us the opportunity for selecting new services and best suit for the customer＇s requirements. In this paper, We firstly propose the category descriptions of constraints in Web Services and analysis how to guide the selection of the services as constraints in Web Services Composition, thus choose an optimal set of services to satisfy the customers requirements. Meanwhile, this approach reduces the dynamic composition of Web services to a constraint satisfaction problem.

关 键 词：约束满足 优化 动态WEB SERVICES
