摘　　要：对基于优势关系的形式背景进行了讨论,在基于优势关系的形式背景上建立了对象偏序集、属性偏序集以及对象-属性偏序集,提出了基于优势关系的概念格的定义及构建方法。这些结论进一步丰富了概念格的理论,对研究基于优势关系的信息系统的规则提取提供了新的思路。The information system based on dominance relations is a kind of widely used information systems in real life. The formal context based on dominance relations was discussed. Three kinds of poset, objects poset, attributes poset and object-attributes poset were established, and the partial order in the posets was discussed. Then, the definition and building method of concept lattice based on dominance relations was proposed. These conclusions further enrich the concept lattice theory,and provide a new way of thinking for rules extraction for the information system based on dominance relations.
