借助于逻辑系统中命题的真度理论,引入命题之间的逻辑度量的概念,并讨论其性质,以此在几种常见的逻辑系统中讨论近似推理问题。
First, by means of the truth degree theory of propositions in logic system, the concept of logic metric between proposi- tions is introduced and its properties are discussed. Then, the approximate reasoning problems in several common logic systems are investigated.
