摘要
在这份报纸，我们建议某距离在 type-2 之间测量模糊集合，并且也，最大的距离措施的一个新家庭被介绍。不同建议距离措施的几个性质被介绍了。另外，我们为订模糊集合基于建议距离测量的 type-2 介绍了一个新评价方法。建议评价方法为订模糊数量满足合理性质。一些性质象坚韧性那样，顺序关系被介绍了。存在评价方法的限制被学习了。为实际使用进一步，为选择最好的选择的一个新方法，为组决策，问题被建议。这个方法与一个数字例子被说明。
In this paper, we propose some distance measures between type-2 fuzzy sets, and also a new family of utmost distance measures are presented. Several properties of differ- ent proposed distance measures have been introduced. Also, we have introduced a new ranking method for the ordering of type-2 fuzzy sets based on the proposed distance measure. The proposed ranking method satisfies the reasonable prop- erties for the ordering of fuzzy quantities. Some properties such as robustness, order relation have been presented. Lim- itations of existing ranking methods have been studied. Fur- ther for practical use, a new method for selecting the best alternative, for group decision making problems is proposed. This method is illustrated with a numerical example.
