字典序偏好的军用物资供应商选择方法

军用物资采购的供应商选择是影响军队战斗力的重要因素。分析了军用物资供应商选择中的群体决策特征和专家的字典序偏好特征，提出了一种解决军用物资供应商选择问题的两阶段群体意见集结方法。第1阶段：个体专家的字典序属性偏好集结算法。从个体专家的字典序属性和供应商排序，计算群体的字典序属性偏好。第2阶段：多专家群体对供应商的字典序偏好集结算法。从多专家对供应商的评分值计算群体对供应商的评分值，结合群体的字典序属性偏好，得出群体最终对供应商的民主选择结果。给出了该集结方法应用于某部队装甲车蓄电池供应商选择的实例。所提的供应商选择方法突出了个体专家的字典序偏好特征，弥补了传统层次分析法采用属性简单加权方法的不足。

Method based on lexicographic preferences to select military material suppliers

The supplier selection of military material procurement is an important factor that affects the army battle effectiveness. The features of group decision making and experts’ lexicographic preferences are analyzed in the choices of military material suppliers. A two stage group preference aggregation method is proposed to solve the problem of military material suppliers’ selection. The first stage is the aggregation method of individual experts’ lexicographic attribute preferences. According to individual experts’ lexicographic attributes and supplier ranking, the group lexicographic attribute preferences are calculated. The second stage is the aggregation method of group experts’ lexicographic preferences about suppliers. According to the multiple experts’ scores about suppliers, the group scores about suppliers are calculated. Combined with group lexicographic attribute preferences, the final democratic result of the supplier selection is gotten. The proposed method is applied into an example about selection of armored vehicle storage battery supplier in a troop. The method of supplier selection proposed highlights the individual experts’ lexicographic preferences and overcomes the deficiency of the attribute weighted in the traditional analytic hierarchy process.
