一类群体决策模型

A Family of Model for Group Decision making

本文利用距离的概念求得一个与各专家所给的数的距离总和最小的数作为对备择对象的总体衡量。首先我们指出海明距离与欧几里得距离的应用可导出现已存在的两个模型，然后对一个特殊的距离给出一些结论。最后，我们利用单调函数去构造更一般的结合算子，从而导出很多常用的算子作为特例。

In this paper, the overall evaluation of alternative is obtained by minimizing some certain distances. Firstly we point out that two extant models can be derived when the Hamming distance and Eulidean distance are chosen. Then our attention is paid to a specific distance for which some conclusions are drawn. Lastly we construct more general aggregation operators by means of some monotonous functions, from which some frequently used operators are obtained as special cases.
