| 摘 要： | 基于区间直觉模糊数隶属度和非隶属度构成的二维几何图形特征给出区间直觉模糊数精确函数的新定义,并将其作为区间直觉模糊数的排序指标,区间直觉模糊数的精确函数值越大,则区间直觉模糊数就越大,进而提出一种权重信息不完全确定的区间直觉模糊多属性决策方法.通过算例分析说明所提出排序指标的有效性和决策方法的可行性.

| Abstract: | In this paper,a new novel accuracy function is first defined by considering the two- dimensional geometry characteristic on membership degree and nonmembership degree of interval-valued intuitionistic fuzzy sets(IVIFSs).The new novel accuracy function is employed to rank alternatives,a higher value means a more preferable alternative.Furthermore, the ranking method is illustrated by numerical examples and compared with other methods, And then a new method for multi-criteria fuzzy decision making with imcomplete weights is established and criteria values for alternatives are IVIFSs.Finally,an illustrative example is given to demonstrate the developed method and to show its validation and practicality. |
