摘 要:针对多目标决策问题,结合决策者心理作用下的决策偏好,以心理距离度量决策者与决策对象之间的关系远近,融合决策者的决策属性值与心理距离,生成二维空间决策坐标集,将坐标集代入灰靶决策矩阵,设计二维欧式空间坐标体系,参照空间坐标点运算法则,求解靶心坐标.采用层次分析法确定指标权重大小,计算坐标点与靶心点之间的距离,构建基于心理距离的多目标加权灰靶决策模型,推求综合效果测度值.案例分析表明,考虑心理距离的灰靶决策模型将决策心理与决策结果紧密结合,为多目标决策提供了更贴合实际决策情景的理论途径.Aiming at the multi-objective decision-making problem, this paper combine with the decision-maker's preference under psychological function, this paper use psychological distance to measure distance between decision makers and decision object, and fuse decision maker's attribute value and psychological distance, in order to generate two-dimensional spatial decision coordinate set, this paper get the coordinate set into the grey target decision matrix, and design two-dimensional Euclidean space coordinate system,according to the space coordinates algorithm to solve the target coordinates. This paper use AHP to determine the weight of index, arid calculate the distance between coordinate point and target point ,this paper establish a multi-objective weighted grey target decision model that base on psychological distance, calculating the comprehensive effect measure. The case study shows that the grey target decision model that consider the psychological distance is closely related to the decision-making psychology and the decision result, which provides a theoretical approach for multi objective decision making.
