摘要: 本文首先定义了一种新区间直觉模糊投影方法,其能更好地度量投影向量之间的相关性。其次,根据区间直觉模糊正负理想方案与备选方案的投影关系, 构建了基于投影方法的未知属性权重求解模型,并在此基础上设计了一种基于投影值的贴近度方法,能实现对备选方案有效排序;最后,用实例验证了该方法的有效性和可行性。

Abstract: In this paper, we first develop a new projection of interval valued intuitionistic fuzzy(IVIF)sets, which is more accurate to measure the relative degree of vectors than the existing projection method. Then we apply this method to solve the IVIF multiple attribute decision making problem, in which the attribute weight information is incomplete. The projections of positive ideal solution(PIS)and negative ideal solution(NIS)are adopted to calculate the alternatives' weights. Thereby, the unknown weights of attributes are determined objectively.Subsequently, an improved overall relative closeness degree is constructed to rank the ordering of alternatives. Finally, a numerical example is provided to show the validity and applicability of the presented method.

Key words: multiple attribute decision making, interval-valued intuitionistic fuzzy set, projection method, TOPSIS
