摘要
研究了不确定语言型多属性决策评价结果与决策者对方案的偏好信息之间存在偏差的问题,提出了基于投影模型的不确定多属性决策方法。该方法通过建立与区间型语言标度对应的术语指标矩阵,及方案综合属性值与决策者主观偏好值之间的投影模型,确定属性的权重,然后运用加权法得到方案的综合属性值,利用已有的可能度矩阵排序公式得到决策方案的排序。最后,通过算例对该方法的实用性和有效性进行了说明。
The uncertain linguistic multi-attribute decision making（ULMADM）problems are investigated,in which the evaluated result is abhorrent with the decision maker reference information.A method based on projection model for ULMADM is proposed. Building the term indices matrix corresponding with linguistic evaluation scale and the projection model between the overall values of alternatives and the decision maker reference information, the method obtains the determinate attribute weights.By using the WAA, the overall values of alternatives are obtained.Then using the priority formula ranks the decision alternatives,Finally,a numerical example is also given to demonstrate the feasibility and practicality of the method.
