摘要
区间值模糊集合是处理不确定、不完全信息的重要基础理论,格蕴涵代数是区间值模糊集上一个重要的研究方向。文章是在区间值模糊集合上,给出了区间补、区间伪补和区间蕴涵三个运算的概念,证明了〈I[0,1],■,■,c,*〉是有余格。与此同时,在区间值模糊集上重新构造了格蕴涵代数(I[0,1],■,■,c,*,■),且讨论了该格蕴涵代数的一些性质。
The interval-valued fuzzy sets is an important basic theory for dealing with uncertainty,incompleteness information.The Lattice Implication Algebras is an important research direction in the internal-valued fuzzy sets.In this paper,the operations are redefined in the interval-valued fuzzy sets,which are the interval complement,the interval pseudo-complement and the interval implication.Furthermore,algebras system 〈I,■,■,c,*〉 is proved complemented lattice.At the same time,the Lattice Implication Algebras(I,■,■,c,*,■)is reconstructed in the internal-valued fuzzy sets,and it's properties are discussed.
