Abstract:
In the light of universality of uncertainty, we propose a decision making model in completed information system. Considering
the attribute reduction, attribute importance and mismatched information, a multiple attribute decision making
model based on importance of attribute is constructed. First of all, decision table is obtained by the knowledge known
and deleting reduced attributes. Also, attributes value reduction obtained to simplify the decision table and rules is extracted.
Then, rules are utilized to make decision for a new problem. Finally, an example is advanced to illustrate our
model.
