面向对象的方法在决策支持系统建立过程中的应用

为了用决策支持系统解决各种具体问题，面向对象方法被引进到决策支持系统的模型库的设计中，首先从多个模型中抽象出具有共性的模型（称为模型类），将这些模型类作为基本的模型放入ＤＳＳ的模型库中，ＤＳＳ在解决具体问题时，根据问题的各种特征，采用面向对象方法的继承机制从基模型类中派生出适合解决该问题的模型，从而使模型更适合具体问题。

OBJECT-ORIENTED METHOD:AN APPLICATION IN BUILDING DECISION SUPPORT SYSTEM

In order to solve a kind of problems by Decision Support System (DSS), object-oriented method is introduced into designing model bases of DSS. Many similar models are abstracted to form base model-classes, these base model-classes are put into model bases of DSS. Ac-cording to the problem which DSS will solve. the inheritance mechanism of the object-orient-ed method is used to derive derived model-classes from the base model-classes. The derived model-class is a kind of model that inherits the attributes of other models. which is more ap-plicable to the specific problem.
