Abstract

Abstract: The attribute reduction is studied in random information system based on dominance relation, by means of the belief measure and plausibility measure in the evidence theory. The inconsistent random objective information system based on dominance and equivalent relations is given and the distribution reduction is discussed. An example is used to illustrate the validity of this method.

Key words: random information system, belief measure, plausibility measure, distribution reduction, discernable matrix

摘要： 以证据理论中的信任测度和似然测度为基本工具，研究了优势关系下随机信息系统的属性约简问题，引入优势-等价关系下不协调随机目标信息系统的概念，并讨论了其上的分布约简，最后给出实例验证了约简方法的有效性。
