| 摘 要： | Ⅱ型模糊集合是传统Ⅰ型模糊集合的扩展,其本质是模糊集合中隶属度值的再次模糊化表示.Ⅱ型模糊集合可以直接处理模糊规则的不确定性,是解决现实环境高不确定性问题的有效手段.本文首先简要给出了Ⅱ型模糊集合与系统的基本概念,然后分别回顾了广义和区间Ⅱ型模糊理论的发展历史.接着分别讨论了广义和区间Ⅱ型模糊系统的计算复杂性问题研究进展,并进一步介绍了基于区间Ⅱ型模糊集合的词计算理论发展状况.最后给出了本文的结论和进一步研究问题的展望.

| Abstract: | A type-2 fuzzy set(T2-FS), which essentially is the refuzzification presentation of membership values in the fuzzy set, is the extension of the traditional type-1 fuzzy set(T1-FS). The T2-FS can directly deal with the uncertainty of fuzzy rules; thus, it is an effective approach to solving the problems with high uncertainties in realistic environment. In this paper, the basic terminologies of the T2-FS and the type-2 fuzzy logic system(T2-FLS) are briefly introduced. The developments of the generalized fuzz... |
