基于语言判断的群决策保障排序方法

Support Sequencing Method of Group Decision-making Based on Linguistic Judgement

根据战时环境和保障决策特点,研究了采用语言型群决策确定保障排序方法,使决策既符合战时实际,又便于发挥群体优势。该方法应用LWA_2(Linguistic Weighted Average)算子将个体决策者的语言判断集成为群语言判断矩阵,再用LA(Linguistic Average)算子给出保障排序。针对集成群语言判断矩阵时权重确定问题,提出了一种采用变精度粗糙集进行分类确定权重的新方法。

The group decision-making sequencing method in order with linguistic judgement is studied in this paper.The method is based on the battlefield environment and characteristic,so it is be close to battlefield condition and easy to exert group advantage.In this method,firstly,individual linguistic judgment matrixs are integrated a group linguistic judgment matrix with the linguistic weighted average operator,then the order is calculated by the linguistic average operator.A new method which is used for distributing the weight to individual decision and based on rough set clustering is proposed,when using the linguistic weighted average operator calculate the group linguistic judgment matrix.
