决策支持系统中的建模知识表示研究

提出一种基于知识的建模支持系统 ,该系统的知识由三部分组成 :构模规则知识、变量类型知识以及数据映射知识 .构模规则知识描述了决策者的构模过程 ;变量类型知识定义了构模规则知识中所有变量的数据类型 ;数据映射知识描述求解过程所需数据的来源 .对于决策者输入的一个实际决策问题 ,系统能够根据问题描述按照构模知识自动进行求解 ,同时对经验进行学习 ,生成经验规则

Study on DSS modeling knowledge representation

A knowledge-based modeling support system is issued in this paper．Its knowledge consists of three parts：modeling rule knowledge，variable type knowl edge and data mapping knowledge．The modeling rule knowledge represents the deci sion-maker's modeling process．The variable type knowledge defines data types f o r all variables in the modling rule knowledge．The data mapping knowledge defin es sources of the data required during solving．After the decision-maker input s a problem，the modeling support system will solve it according to the modeling knowledge automatically and at last commit the result to the decision-maker． M eanwhile， machine learning is adopted to acquire knowledge during problem solvi ng．
