| 摘 要： | 进行SOA系统构建时，在选择同一功能服务不同物理实现的过程中，需要考虑用户适合度。提出根据用户需求确定服务QoS属性集的方法，该方法用扩展的WSDL协议描述服务QoS，量化服务QoS和用户QoS需求。构建基于用户请求的服务质量模型和相应算法，完成对最佳用户适合度服务物理实现的选择。

| Abstract: | It is necessary to consider the user’s suitability in the process of different physical implementation in the same functional service when constructing the SOA. This paper proposes a method to definite the attributive set of service Quality of Service(QoS) according to the user’s request. In this method, the service QoS is described by the extended WSDL and the QoS of service and user is quantified. It constructs the QoS model based on the user’s request and the relevant algorithm to finish the choice of the physical realization of service with the best user’s suitability. |
