群决策中多阶段多元判断偏好的集结方法研究

Aggregation approach of multiple stages multiple judgment preferences styles in group decision-making

研究群决策过程中决策者基于多个决策阶段、多种结构形式的判断偏好集结方法.基于互反判断偏好与互补判断偏好的转化公式,将多种类偏好的结构一致化;利用决策者判断偏好的一致性水平和与群体综合偏好偏差的距离,提出了确定决策者权重的方法;建立了基于决策先验信息的多阶段偏好集结的决策阶段赋权模型.根据各决策阶段的权重,将多阶段判断偏好集结成群体综合偏好.

A problem of aggregation approach of multiple stages multiple judgment preference styles is studied in group decision-making process. Multiple preferences are translated into single one preference style based on the reciprocal comparison matrix and complementary matrix translation formula. The weight of the decision-maker is suggested according to the consistency level of the decision preference and the deviation of the individual and the group. The weight of the decision-stage is presented based on the priori information. Following that, the multiple stages and multiple preferences are aggregated into the group preference.
