针对群决策中基于语言判断矩阵形式偏好信息的方案排序问题,提出一种新的排序方法。给出有关语言判断矩阵的完全一致性、满意一致性、LOW A算子及图论的连通图和树等若干定义,得出构造具有完全一致性或满意一致性的语言判断矩阵满足的条件。根据图论的无向连通图理论,给出基于语言判断矩阵的群决策的方案排序方法。通过一个算例说明本文提出的分析方法。 Aiming at the scheduling problem of group preference information based on language judgment matrix, a new sorting method is proposed. This paper gives some definitions about complete consistency and satisfactory consistency of linguistic judgment matrix, connected graphs and trees such as LOW A operator and graph theory, and then obtains the conditions for satisfying the language judgment matrix with complete consistency or satisfactory consistency. According to graph theory of undirected connected graphs, a method of group ranking decision method based on linguistic judgment matrix is ​​given. An example is given to illustrate the analysis method proposed in this paper.
