摘要
直觉模糊数是处理模糊问题的一种有效的信息表达形式,其排序方法是研究的热点问题之一.基于均匀分布的原理,提出新的直觉模糊数序优先度的概念,给出各种情形下的序优先度的计算公式,并探讨了直觉模糊数序优先度的若干性质.给出了基于直觉模糊数序优先度的群评价算法.实例分析表明本文提出的方法是可行有效的.
Intuitionistic fuzzy number is an effective information form of dealing with fuzzy problems its ranking method is one of the hot research issues. The new concept of ranking priority degree for intuitionistic fuzzy number sequence is put forward based on the principle of uniform distribution in this paper. We also give the formulas of calculating the ranking priority degree for intuitionistic fuzzy number under several cases and discuss its properties. Based on the ranking priority degree of intuitionistic fuzzy number sequence, group evaluation algorithm are given in this paper. An example is illustrated to show that the proposed method is feasible and effective.
