Abstract: This paper introduces a new method, case-based reasoning (CBR) and presents the principle, structure and function of the decision support system of supplier selection based on case-based reasoning. A lot of critical steps in the decision support system of supplier selection based on case-based reasoning are discussed. An example is given to validate the algorithm. The results show that the method is effective. The research provides a system model for the decision of supplier selection.

Key words: inductive indexing method, nearest neighbor algorithm, case-based reasoning, supplier selection, decision support system

摘要： 在介绍了基于案例推理方法的基本原理基础之上，分析了基于案例推理技术的供应商选择决策支持系统的工作原理、框架结构及功能；重点论述了基于案例推理的供应商选择决策支持系统系统中的一些关键步骤，并结合实例给出了基于案例推理的供应商选择与评价方法，用来验证基于案例推理技术在供应商选择决策支持系统中应用的可行性和有效性，为企业供应商选择决策提供了一个系统模型。
