摘　　要： 　　虚拟企业作为的一种企业间的协同合作模式，其成员企业是动态的、不确定的，并且各成员企业运行模式所依赖的底层基础架构、通信协议以及对外交换的数据格式都有所差异，整个动态联盟处于一种异构的、分散的环境中。如何保障在成员之间方便地、低代价地实现无缝集成和互操作，从而提供一个动态的企业间的应用集成环境，是构建虚拟企业的关键问题之一。 　　目前，多数的虚拟企业应用集成方案一般都是“独立”地针对某个特定应用来设计，并且集成双方之间实现的是紧耦合机制，难以在使用期进行再定制。而WEBSERVICES技术作为一种新型的分布式对象技术，具有完好封装、松散耦合和高度可集成能力等特点，能够很好地满足虚拟企业成员的动态性要求，并解决成员之间应用集成的架构相异问题，从而使虚拟企业的应用集成环境具有良好的可扩展性和易维护性。 　　本文首先对企业应用集成的内涵进行了深度和广度的阐述；结合虚拟企业的特征，分析并总结了虚拟企业应用集成在系统体系结构和集成机制两方面的特性需求；进而对现有的虚拟企业应用集成方案进行了不足分析，并详细地分析了WEBSERVICES技术在虚拟企业应用集成构建中的优势所在。在上述分析的基础上，提出了一个基于WEBSERVICES技术的面向服务架构(SOA)的虚拟企业应用集成模型，详细的设计和阐述了集成体系架构中的核心企业方、成员企业方以及客户方的各自功能和交互，并深入探讨了如何利用WEBSERVICES接口集成调用合作伙伴所提供的应用服务，以及私有UDDI和统一身份认证服务的创建。最后，将模型应用于一个虚拟企业的分布式集成订单处理系统，具体地实现了成员之间的应用服务松散耦合的集成及调用。从而验证了基于WEBSERVICES的虚拟企业应用集成模型的可操作性和正确性，为进一步实现复杂虚拟企业应用系统做了必要的理论与实践准备。 As a collaboration schema over enterprises, the member enterprises of Virtual Enterprise /(VE/) are dynamic and changeable, the elementary architecture, communication protocol and external exchanging data format of every run schema are different, and so the whole dynamic alliance is under an isomeric and decentralized circumstance. How to implement seamless integration and operation mutually over members, providing a dynamic application integration circumstance over enterprises is one of the key problems in building VE.Most existing VE integrated solution are designed due to some specified application independently, and the integration both sides is strong coupling, so it is difficult to customize in lifetime. Web Services is a new distributed object technology, with good packaged, incompact coupling and strong integration ability features etc. It can satisfy the dynamic request of VE members, and solve the isomeric problem over members, so that the application integration circumstance of VE has well extensibility and can be maintained easily.In this paper, firstly the meaning of enterprise application integration is expatiated from depth and extent; with the features of VE, the special requirements of VE application integration are analyzed and summarized from system architecture and integration mechanism sides; then the deficiency of existing VE integrated solution is analyzed, and the advantage of building VE application integration with Web Services is analyzed in detail. Based on the above analyses, a VE application integration model base on Web Services and SOA is put forward, in this integrated architecture the function and interaction of core enterprise, member enterprise and client are designed and expatiated, with Web Services interface integrating and invoking the application services provided by associates is discussed in depth, and private UDDI and Uniform Authentication service are built. At last, the model is applied to a distributed VE integrated order processing system, incompact coupled integrating and invoking the application services over members are implemented concretely. So the maneuverability and correctness of VE application integration model base on Web Services are validated, further, the theory and practice are prepared to implement complicated VE application system.
