摘　　要：一般的ＤＦＴ算法都假定输入和输出序列长度相等，实际的情况并非总是如此。鉴于此，文中讨论了输入和输出序列长度不相等的这类ＤＦＴ的快速计算方法，其结果比Ｓｋｉｎｎｅｒ的剪枝法和Ｓｏｒｅｎｓｅｎ，Ｂｕｒｕｓ的变换分解法更简洁高效。Fuzzy relation is one of the fundamental concepts in fuzzy set theory.This paper presents a kind of fuzzy consistent relation,which satisfies center division ransitivity and thus conforms to the psychological characteristic of human decision making.When discourse is finite,fuzzy consistent relation may be described by fuzzy consistent matrix.The combined operation and construction of fuzzy consistent relation are discussed.Finally,the applications of fuzzy consistent relation in system evaluation are explained shortly.
