Interval-valued Fuzzy Inference

Aimed at interval-valued fuzzy relation,the compound operation of interval-valued fuzzy relation and its operations are discussed.Based on this compound operation,two types of the interval-valued fuzzy inference are researched,including the simple interval-valued fuzzy inference and the multiple interval-valued fuzzy inference,and four kinds of mathematical models of the interval-valued fuzzy inference are given.Finally,one practical example is used to illustrate that our proposed interval-valued fuzzy inference method is reasonable.
