摘要: 将王国俊教授在R0-型逻辑系统中建立的R0-蕴涵算子应用于模糊数学理论之中,在非空集合X为论域的模糊集族F(X)上定义了一种新型运算-R0蕴含运算,并讨论了F(X)上R0-蕴含运算的一些基本性质。通过[R0]-蕴含运算在F(X)上定义了一个二元模糊相似关系-R0-相似关系,并对其性质进行了较为详细的讨论。在有限论域X确定的模糊集族F(X)上给出了几个R0-相似关系的具体实例。

Abstract: R0-implication operator proposed by Professor Wang Guojun in the R0-type logic system has been applied to the fuzzy mathematical theory,and a new kind of computation-R0-implication operation,is defined on the family F(X) of fuzzy sets,and its basic properties have been discussed.Then,a binary fuzzy similarity relation-R0-similarity relation on F(X) is defined through the R0implication,and its properties are discussed in detail.Finally,several examples of [R0]-similarity relation are provided by the R0implication operator on F(X) with the finite domain X.Not only the results of this paper make an application of the R0-type logic system,but also enrich the methods of studying fuzzy mathematics.
