| Abstract: | The concept of distribute consistent set for lattice-valued decision table is proposed and some sufficient and necessary conditions for an attribute set to be distribute consistent set are given.The discernibility function of distribute reduction is constructed and from which an approach for distribute reduction is provided. |
| Keywords: | lattice-valued decision table distribute consistent set distribute reduction discernibility function |
