Abstract
A new method for calculating core attributes of a decision table is proposed. In particular, this method is better than other methods for inconsistent decision tables. In this paper, the concept of condition-decision impact factor is proposed, some characteristics are studied as well. An important theorem for judging core attributes is given. Based on the theorem, an algorithm for calculating core attributes is presented and is followed by an example to illustrate the validity of the algorithm.
