一种新的有优序综合评价的群决策方法

在群决策中存在着多个决策者根据自己的知识、经验和偏好独立选择决策方法 ,对决策方案集作出决策后 ,如何综合确定群体决策方案的多人多指标群决策问题。针对这类问题中决策信息量较少 ,而决策一致性较差的特点 ,在分析一些决策方法的基础上 ,提出了一种多人有优序综合评价的群决策方法。该方法首先采用总体偏差法对决策方案进行分类 ,然后对元素个数多于 1的类采用足码法进行排序 ,最后综合得到整个决策方案的排序。通过具体算例的比较 ,表明该方法弥补了原有方法的不足 ,具有明显的有效性。

A New Group Decision-Making Method of Multi-Decision-Maker Synthetical Evaluation With Priority

After multiple decision makers select decision making methods independently according to their knowledge, experience and preference and make decision on decision making alternatives set, the multi decision maker and multi index group decision making problem of how to comprehensively determine group decision alternatives set will arise in group decision making. To solve the problem of insufficient decision information and poor decision consistency, after analyzing respective characteristics and limitation of collectivity deviation method, leg mark method and correlation improved method especially studying the counter example and rank reversal, the paper puts forward a new group decision making method of multi decision maker synthetical evaluation with priority. The method firstly classifies the decision making alternatives set using collectivity deviation method , and then sorts the class which element number is more than 1 by leg mark ,thus establishing the priority of the decision making alternatives set. Furthermore, the paper proves the obvious effectiveness, high reliability and operational convenience through comparison of examples with the former results.
