摘要
针对多属性评定中相对于决策目标属性之间存在冗余和相关性,以及装备评定可获得的信息量少等特点,将灰关联度方法和粗集理论结合,实现了装备综合评定中的不同数据类型属性的约简,提高了综合评定的效率。根据属性之间的灰关联度作为属性约简的标准,实例分析、研究了不同属性约简标准下的综合评定,证明了该方法的有效性。
Among all of attributes of equipment, there are some redundant and/or correlative attributes. And com- bining grey correlative degree with rough set theory, a novel comprehensive evaluation method was presented, which was used to solve attribute reduction and deficient information in evaluation of equipment. According to the example analysis, the validation of the method was proved.
