| 摘 要： | 不完备不一致决策系统中,条件属性下的相容划分与决策属性下的等价划分形成了复杂的交集,导致出现了多种不同的约简概念,从而使约简问题变得更加复杂.本文将最大分布约简的概念引入不完备不一致决策系统中,然后研究其在不完备不一致决策系统中的性质,发现其核属性不具备传统约简核属性通常所具备的继承特性,因而不能通过增加属性的方法来计...

| Abstract: | In inconsistent incomplete decision systems(IIDSs),some tolerance classes in tolerance partition overlap more than one decision class,so as to produce complex overlapping subsets between tolerance partition and decision partition.This leads to occurrence of many concepts of reductions in IIDSs and makes the reduction problem more complex.Therefore,the concept of maximum distribution reduct is extended to IIDSs in this paper,then,some of its properties in IIDSs are analyzed.It is found that,unlike other redu... |
