【摘要】：本文在大群体聚类和冲突测度基础上,构建了基于冲突度的复杂大群体冲突消解协商模型,该模型主要由大群体偏好结构分析、冲突分析和冲突协调三个部分构成。在Spss和Matlab软件辅助下,通过该模型进行决策,能够快速获得大群体一致认可的决策结果。为此,本文重点研究快速决策过程中复杂大群体的冲突协调,为快速决策支持系统提供理论依据。论文的主要研究工作如下:在矩阵相似度测度模型基础上,通过求得的相似度矩阵绘制聚类谱系图进行大群体聚类,将单层次大群体决策问题转化双层次小聚集体决策问题,并且利用信息熵理论在权重确定方面的便捷性,通过构建距离熵模型对决策者进行聚类内以及聚类间权重初步确定。利用冲突测度模型对复杂大群体决策个体冲突度、聚集间冲突度以及大群体综合冲突度进行度量,并在传统的不完全信息下的单阶段大群体决策模型基础上,考虑时间约束、冲突约束以及信息失真约束构建了基于不完全模糊偏好关系矩阵的多阶段冲突消解协商模型。在冲突消解过程中提出了基于序列差的权重再分配模型,对序列差计算过程中的相关名词进行定义,并限定了序列差权重再分配模型的适用环境。在证明偏好修正与权重再分配方法对于冲突消解的可行性以及分析两种方法各自适用环境基础上,构建混合冲突消解模型,实现在多重约束下冲突的快速消解,并通过一个模拟算例证明了模型的有效性。
[Abstract]:On the basis of large group clustering and conflict measure, a conflict resolution negotiation model based on conflict degree is constructed in this paper. The model is mainly composed of three parts: large group preference structure analysis, conflict analysis and conflict coordination. With the aid of Spss and Matlab software, the decision can be quickly obtained by using the model. Therefore, this paper focuses on the conflict coordination of complex large groups in the process of rapid decision making, which provides a theoretical basis for the rapid decision support system. The main research work of this paper is as follows: on the basis of matrix similarity measure model, using the obtained similarity matrix to draw the cluster pedigree diagram for large group clustering, the single level large group decision making problem is transformed into the bilevel small group decision making problem. Using the convenience of information entropy theory in weight determination, the distance entropy model is constructed to determine the weights of decision makers within and between clusters. The conflict measure model is used to measure the degree of individual conflict, the degree of inter-cluster conflict and the degree of comprehensive conflict of large group in complex large group decision making. Based on the traditional one-stage large group decision-making model with incomplete information, time constraints are considered. A multi-stage conflict resolution negotiation model based on incomplete fuzzy preference relation matrix is constructed by conflict constraints and information distortion constraints. In the process of conflict resolution, the weight redistribution model based on sequence difference is put forward, and the relevant nouns in the process of sequence difference calculation are defined, and the applicable environment of sequence difference weight redistribution model is defined. On the basis of proving the feasibility of preference modification and weight redistribution for conflict resolution and analyzing the applicable environment of the two methods, a hybrid conflict resolution model is constructed to resolve the conflict quickly under multiple constraints. The validity of the model is proved by a simulation example.
