摘要:

大群体决策问题是一类特殊的群决策问题,最大特点是有大量决策者参与。本文旨在探索一种大群体决策新方法,解决基于公众评价的大群体决策问题。该方法首先根据决策者所属领域不同将回收的大量评价数据进行分组,依据公众评价数据的特点分别用正态分布和对数正态分布拟合每组数据,选择拟合效果较好者;其次采用主、客观集成赋权法确定各组权重,其中主观权重由该组人数比直接确定,客观权重由该组组内评价数据的一致性确定;然后按照正态分布性质将各组分布集结;最后计算两两对象之间的优势度,得到优势度判断矩阵,并利用PROMETHEEⅡ的思想进行决策。通过案例分析和对比研究,验证了所提方法的可行性和优越性。

关键词: 多属性群决策, 大群体, 正态分布, 对数正态分布, 优势度

Abstract:

Large group decision-making (LGDM) is a special group decision-making (GDM) issue, in which a large number of persons take part in the decision-making process. The objective of this paper is to develop a new method to address the LGDM issue which is based on the public evaluation. Firstly, we divide the large evaluation data into several groups according to decision makers' professions. Normal distribution and logarithmic normal distribution are used to fit each group of data and select the better one. Secondly, the decision weight of each group concerning each object is obtained by aggregating the subjective weight, which is provided by the data rate, and the objective weight is determined according to the level of consensus among participators' evaluations. Thirdly, according to the nature of normal distribution, the normal distributions are assembled to one. Finally, by calculating the dominances of any two objects, we get the dominance matrix for decide making based on PROMETHEEⅡ. The practicality and superiority of the suggested method is verified through case study.
