案例推理在大型机电产品方案设计IDSS中的应用研究

针对大型机电产品方案设计中智能决策支持系统（IDSS），讨论了方案库和指标库的建立，并将其用关系数据库的格式进行存储；提出了多种检索方式协同检索策略，从而可以准确地检索到相近案例，对产品方案设计论证过程提供有效的决策支持。

Study on the Application of Case Reasoning in IDSS for the Scheme Designs of a Large-Scale Mechanical-etectrical Product

Aiming at the Intelligent Decision Support System (IDSS) for the scheme designs of a large-scale mechanical-electrical product,a method of building the index base and the plan base in IDSS is discussed in this paper. They are built according to the format of relational database.A retrieval strategy combining several retrieval methods is put forward. Thus similar cases can be found out accurately to give the valid decision support to the argumentation process of products design plan.
