在不完备信息系统中，定义了一种新的优势关系，提出了优势关系的支配集与被支配集的相对约简以及优化决策规则获取，利用布尔推理理论求得优势关系的支配集与被支配集的相对约简，从而得到优化决策规则。
在不完備信息繫統中，定義瞭一種新的優勢關繫，提齣瞭優勢關繫的支配集與被支配集的相對約簡以及優化決策規則穫取，利用佈爾推理理論求得優勢關繫的支配集與被支配集的相對約簡，從而得到優化決策規則。

In incomplete information system, a new dominance relation is defined. The relative reduction and optimal decision rules are proposed, by defining discernibility function of dominating class and dominated class, and using Boolean reasoning techniques, reduces of dominating set and dominated set are obtained, and as a result, optimal decision rules are introduced.
