基于三维形态的决策支持系统研究

A Three Dimensional Decision Support System

描述了群决策的三维形态，并分析了三维形态的关系。在此基础上，提出了基于三维形态的群体决策支持系统ＧＤＳＳ（ＧｒｏｕｐＤｅｃｉｓｉｏｎＳｕｐｐｏｒｔＳｙｓｔｅｍ）原型结构，并介绍了该系统工作原理以及主要模块的功能。

Existing decision support systems (DSS) are two dimensional and generally employed by just a single decision maker. We propose a three dimensional DSS or GDSS (group DSS) that can be used by a decision group consisting of many members. Fig.1 shows the three dimensions of our GDSS: process dimension, problem dimension, and member dimension. In section 2, we discuss six relationships: (1) problem relationships R q , (2) member relationships R m, (3) process relationships R p, (4) relationships between problems as a group and members as a group R qm , (5) member process relationships R mp , and (6) problem process relationships R qp . Our GDSS was implemented and applied to solving problems involving many decision makers. Its preliminary success was certified by a committee of experts.
