基于灰色关联度的多阶段语言评价信息集结方法

Aggregation of multi-stage linguistic evaluation information based on grey incidence degree

研究多阶段语言评价信息的群集结方法.采用二元语义进行语言信息转化;依据评价过程中事物发展规律,提出了方案量变和质变的判定方法和评价者判断质量变化的测度指标;建立了基于灰色关联度的时间权重确定模型;研究多阶段群体差异最小的评价者定权模型,提出了多阶段信息的群集结方法.算例分析表明了方法的应用步骤和有效性.

The aggregation approach of multi-stage linguistic evaluation information is studied. The linguistic information is transformed in two-tuple linguistic ways. The check index of quantitative change, qualitative change and the evaluation quality index of decision maker are proposed according to the alternative development rule. The weight of stage is set up by the stage grey relation calculated with the stage weight setup in advance. In addition, the weight model of decision maker is precented based on the least distance group preference. Then, the group aggregation method of the multi-stage is developed. An example shows the application process and efficiency.
