一个面向对象的决策支持系统生成器模型

A TOOL MODEL FOR BUILDING DECISION SUPPORT SYSTEMS BASED ON OBJECT ORIENTED TECHNIQUE

以面向对象的方法体系为出发点，提出了建立面向领域的决策支持系统开发工具ＯＯＤＳＳＴ，并给出了领域对象描述语言ＯＯＭＤＬ，以此为基础在给出ＤＳＳ对象系统中知识对象的框架结构描述的同时，引入了对象说明名表和属性关系名表的定义，这些概念的提出进一步扩充了系统面向领域的特性。模型的生成以继承关系网格的构成为前提。模型的实现基于系统内部的自动消息响应机制。

Based on a new object-oriented technique,this article introduces a too1(OODSST) forbuilding Decision Support Systems(DSS),including corresponding modeling descriptive language(OOMDL)and the organization of systems。 The concepts of knowledge object andnetwork of inheritance relation are presented in order to increase the knowledge expressivencess of domain objects in systems. Messages are used to organize all of the objects thatare defined by systems and application domains.
