摘要： 针对业务构件设计一直是基于构件的企业信息系统软件开发中的研究难点这一问题，该文给出了一种基于UML语言，由业务功能视图、业务实体视图、业务组织视图、业务控制视图组成的业务模型描述方法。并在业务模型语义分析的基础上建立起聚类算法的样品间及类间关联值的计算公式，有效地将聚类算法引入业务构件划分过程，并通过谱系聚类图来确定构件划分的最优设计结果。给出了业务构件接口设计的关键步骤和方法，为构件划分和设计提供了一套可遵循的参考标准，以有效提高构件设计的质量。

Abstract:

Business component design is one of the hottest research issues in the development of enterprise information system. A business model description method is given, which uses business function view, business entity view, business organization view, business control view. Based on the semantic analysis of business model, relationship formulas between sampling points and relationship formulas between clusters are given. And the cluster algorithm is introduced to make the business component partitioning process more effectively. Cluster process diagram is brought out to identify the best component design result. The key steps of business component interface design are given as well. All of these provide feasible reference standards for component partitioning and interface design, and greatly enhance the quality of component design.

Key words: business model, cluster algorithm, component design
