摘要
利用S-粗集理论和元素迁移的随机性,提出元素迁移的信度及信度函数的概念,提出随机副集的概念,给出了随机副集的(α,β)-随机生成,(α,β)-强随机生成;讨论了随机副集的生成特性.
By using the theory of S-rough sets and random characteristics of element transference, the concept of reliability of element transference and reliability function are presented. The concepts of random assistant sets are presented. The random assistant sets (α,β)-generation and random assistant sets (α,β)-strong random generation are given. The generation characteristics of random assistant sets are discussed.
