| 摘 要： | 基于函数S-粗集,结合函数迁移的随机性,提出了函数单向SPF-粗集概念,并给出它的数学结构。研究了函数单向SPF-粗集概率特性。证明了在概率的意义下,函数单向SPF-粗集是函数S-粗集,函数单向S-粗集的推广；函数S-粗集,函数单向S-粗集是函数单向SPF-粗集的特例。

| Abstract: | Based on function S-rough sets and the randomness of function transfer,the concept of function one-direction SPF-rough sets was put forth,and their mathematical structure was given.The probability characteristic of function one-direction SPF-rough sets was also discussed.It was proved that a function one-direction SPF-rough set was the generalization of function one-direction SPF-rough sets,and the function one-direction S-rough sets was a special case of function one-direction SPF-rough sets according to the probability. |
