具有偏好关系网络结构稳定的群决策协商控制模型

Group decision-making controllable model with preference relations network structure stabilization

挖掘群决策偏好关系结构信息,提出决策者个体偏好与群体偏好关系以及网络结构稳定的群决策协商控制模型.根据模型提供个体偏好参考基准,计算决策者及群体的偏好相容性测度.通过决策者建立、取消(断开)或加强与其他决策者的链接以及对偏好信息进行调整的策略建议,促使决策者个体偏好、群决策偏好关系网络结构正向演化,在模型框架下保证群体偏好网络结构稳定,达到群体偏好信息相容性极大的目的,为进一步信息集结提供依据.

This paper introduces a model for group decision-making problem based on both the preferences of decision- makers and the group and the stability of network structure. References of the individual preferences are provided according to the model, and the measurement of preferences consistency about both decision-makers and the group is calculated. The decision-makers establish, cancel（disconnect） or strength the links between others, and regulate their preferences in the model. Both decision-makers preferences and the group preferences network structure can develop to the positive evolution in the model. Structural stability of the group preferences network structure can be guaranteed, and the group preferences consistency maximization is achieved, which provide more convenient solutions for information aggregation .
