In order to solve the problem of rough sets theory in continuous attributes discretization a heuristic discretization algorighm on objective planning is proposed. With the wealthy calculation on objective planning and the importance of attributes considered, the heuristic discretization algorithm not only reduces decision rulers but also finishes attribute value reduction. The comparison between the algorithms in this paper and the other paper on teataste signals shows the algorithm in this paper produces less rulers and the short average length of rulers. The rulers in this algorithm have been decided, too. Consequently, the decision system has a high efficiency.
