| 摘 要： | 决策支持系统(简称DSS)的一个主要目标是帮助决策者解决半结构的决策问题。从DSS的定义中,也可知道DSS应能支持决策过程的各个阶段。在DSS的发展过程中,许多学者致力于使DSS实现上述目标,但已有的决策支持系统绝大多数只强调决策过程中的选择阶段,而对决策问题描述和形成则缺少支持。这说明了DSS的重要组成部分——模型管理和建模支持系统的功能太弱,无法对模型的建立提供良好支持,无法对决策问题的结构化过程提供支持。

| Abstract: | Knowledge representation for models is a key issue in IDSSs. First, this paper discusses the demand of model representation for modeling process, and reviews the methods of knowledge representation for models. Then, a method of knowledge representation for models, which is based on frame and operator, is presented. In this method, variables and functions of a model are seperated, and a kind of symbolic operator is used to express a function. So, the model operation is combined with the symbolic knowledge processing. |
