摘　　要：为获取具有较高重用度的业务构件,提出了一个基于领域业务模型的可重用构件设计方法。通过对现有业务模型的分析,提出了一个面向构件化分析的领域业务模型,描述了组成模型的业务元素,以及元素之间的关系。通过分析该模型中表达相同业务需求的特征,给出了等价特征集的划分算法和基于业务元素关系图的构件识别算法。在构件的识别过程中,给出了计算多个业务元素之间相似度的公式和测量业务构件粒度的方法。最后,开发了可重用业务构件提取工具,以帮助软件设计人员从领域业务模型中获取高质量的可重用业务构件。To capture business components with high reusability, a reusable component design method based on domain business model was proposed. Firstly, by analyzing current business models, a domain business model oriented to component analysis was proposed. Main business elements and relationships among them were formally defined. By analyzing characteristics of domain business model expressing the same business requirements, the partition algorithm of equivalent feature set and the identification algorithm of reusable business component based on business element relationship graph were proposed. In the identification process of reusable business component, the formula of calculating resemblance degree among business elements was given, which extended Sorenson coefficient . To acquire high quality business components, the method measuring business component granularity was also presented. Finally, a tool RBCET was built by using this method to help reusable business components＇ extraction from domain business model.
