摘要
通过引入随机化映射和真度权函数等概念,提出了三值命题逻辑系统中公式的随机真度的等价定义,给出了随机真度的推理规则,研究了随机度量空间上逻辑运算的连续性等问题,为在三值命题逻辑系统中进行近似推理提供了另外的方法.
By introducing random mapping and truth degree weight function,the definition of equivalence of the randomized truth degree of formula in 3-valued propositional logic is obtained.The inference rule based on randomized truth degree are given and continuity of logical operations on randomized logic metric spaces are studied.Another way for approximate reasoning in the logic system is provided.
