Classic rough set theory based on equivalence relation takes complete system as object of study , and divides the region into some non-intersect equivalence class; But, in the real life, because of the errors in data measuring, understanding of data, or the restriction in data collection , it can make the decision-making system incomplete, that is, value of attribution of some objects is unknown, which restrains development of the theory to practical direction.

经典粗糙集理论以完备系统为研究对象，以等价关系为基础，通过等价关系将论域划分为互不相交的等价类；然而，在现实生活中，由于数据测量的误差，对数据理解或获取的限制等原因，使得在知识获取时往往面临的是不完备系统，即可能存在部分对象的一些属性值未知的情况，这就极大地限制了粗糙集理论向实用化方向发展。
