摘要
针对权重信息不完全未知且属性值为直觉梯形模糊数的多属性决策问题,给出了基于直觉梯形模糊数得分函数和投影模型下的多属性决策方法,通过投影法建立了非线性规划模型,并通过数学软件得到各属性权重,通过投影率作为排序指标,进行排序择优。最后通过实例说明了该方法的有效性。
With respect to multiple attribute decision making problems in which the attribute weight information is incomplete and the attribute values are intuitionistic trapezoid fuzzy numbers, this paper gives a new method based on the score function of intuitionistic trapezoid fuzzy numbers. With respect to multiple attribute, decision making problems in which the attribute weight information is incomplete and the attribute values are intuitionistic trapezoid fuzzy numbers , and how decisions by projection method for nonlinear planning model, the authors use software of mathematics to attain each attribute weight and ranking with the projection rate on the ideal score to solution. Finally, a numerical example is provided to illustrate the effectiveness of the method.
