摘　　要：基于SOA的服务建模在企业中得到了广泛运用,针对SOMA服务建模过程中基于用例间包含与扩展关系对可重用候选服务进行选定时存在功能重用性用例确定不准确的问题,给出了加入用例泛化关系的可重用候选服务选定方法,完善了可重用性候选服务的选定。实践表明,改进后的候选服务选定方法不仅使简化了可重用性候选服务选定过程,还提高了可重用性候选服务选定的准确率。SOA-based service modeling is widely used in the enterprise applications. During SOMA service is modeling, according to the identification inaccuracy of function reusability between use case when selecting reusable candidate services, based on the expansion and containment relationship, the selection process of reusable candidate services are provided, which join generaliza- tion relationship between the use case, and the selection of reusability candidate services is improved. Practice shows that the im- proved candidate services selection methods not only simplify reusable candidate selection process, but also improve the selection accuracy of reusability candidate services.
