TFN-AHP模型在敏捷虚拟企业盟友选择中的应用

为提高层次分析法(AHP)在敏捷虚拟企业(AVE)盟友选择问题中的实际应用能力，提出一种基于三角模糊数(TFN)理论的模糊AHP(TFN AHP)模型.该模型利用对数最小二乘法求取指标权重，采用TFN取代判断矩阵中的数据元素，结合TFN算法的性能，融合群组评价中的不一致性信息.理论分析及实例结果均表明，该模型使专家对待选方案的评价方法更加符合人类的思维模式，能有效综合群组意见，对每一项指标都能获得群组评价的一致性结果.该模型结构简单规范，结果公平合理.该模型使专家在每一层次上都能得到供决策参考的有效信息，提高了求解实际评价问题的效率.

Partner selection and evaluation in agile virtual enterprise based upon TFN-AHP model

To enhance the validity of the analytic hierarchy process(AHP) in partner selection problems during the formation of the agile virtual enterprise(AVE),a new trigonometric fuzzy number-AHP(TFN-AHP) model was given.The criteria weights were calculated using the logarithmic least square method in the model,the data element of judgment matrix was replaced by the TFN,and the inconsistent information produced in the group decision-making process was synthesized and eliminated by combining the properties of TFN algorithms.Theoretical analysis and case results show that the proposed model makes experts' judgment method more accordant with human thought mode,handles disagreements between different rankings more effectively,and enables experts to obtain the consensus decision according to every criterion.The model structure is simple and normative,and the evaluation conclusions are fair and reasonable.The model makes experts get valid information from each decision element at every hierarchy for the reference in decision-making,and improves the efficiency of solving practical evaluation problems.
