| Abstract: | Based on attribute's dynamic transfer property of two direction variation S-rough sets and statistical information in knowledge base, the two direction variation S-probability rough sets was put forward. The attribute's probability characters of two direction variation S-probability rough sets were discussed. These properties are the bases of dynamic decision-making. Using the above discussion, a special application example was given. |
| Keywords: | two direction variation S-rough sets attribute's transfer two direction variation S-probability rough sets probability accuracy probability roughness |
