| Abstract: | By using 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. |
| Keywords: | S-rough sets random assistants (α β)-random generation (α β)- strong random generation generation characteristics of random assistants |
