| 摘 要： | 在赋值格为0,1]的模糊逻辑系统L*中,基于条件概率的思想和赋值集的随机化方法提出了公式的条件随机真度,证明了条件随机真度的MP规则和HS规则。引入公式间的条件随机相似度和条件伪距离,建立了条件随机逻辑度量空间,推导出条件伪距离的若干性质,证明了条件随机逻辑度量空间中逻辑运算的连续性,并初步研究了给定条件下的近似推理理论。

| Abstract: | In the fuzzy logic system L * with valuation lattice ,based on conditional probability and using the randomization method of valuation set,the concept of conditional randomized truth degree of formulas is introduced.The MP rule and HS rule of conditional randomized truth degrees are proved.The concepts of conditional randomized similarity and conditional pseudo-metric between formulas are presented and conditional randomized logic metric space is built.Several properties of conditional pseudo-metric are deduced and it is proved that the logical operations are continuous on conditional randomized logic metric space.Then the theory of approximate reasoning under certain information is studied. |
