摘要
首先讨论了粗糙模糊数(RFN)的性质和运算法则,进而定义了粗糙模糊数的贴近度.在此基础上,分别给出了粗糙模糊数的距离贴近度,最大 最小贴近度,最小平均贴近度以及格贴近度.可用于在实际问题中对模糊信息的表述及信息加工.
In this paper, some properties and operation laws of rough fuzzy number are discussed. The concept of the closeness of rough fuzzy number is defined. Based on these, the closeness of distance, the least and greatest closeness, the least average closeness and the closeness in the lattice for rough fuzzy numbers are given. Expressions and information processes fuzzy information in the availably practical problems.
