| Abstract: | In this paper,by introducing the concept of inclusion degree to incomplete ordered information system,the significance of attribute was defined.Then,an inclusion degree-based algorithm for attribute reduction under incomplete ordered information system was proposed.The experimental results show that this algorithm can find the reduction of an incomplete ordered information system. |
