Rough隶属函数关于集合并与交的一种高精度计算方法

A HIGHER ACTUATE WAY FOR COMPUTING THE ROUGHMEMBERSHIP FUNCTIONS FOR THE SETUNION AND INTERSECTION

近些年来,许多处理近似问题的方法陆续被提出,其中利用Rough集理论计算两个集合的并和交的Rough隶属函数方法是被用较多的一种方法,但毕竟该方法精度较差。为此,介绍了一种精度较高的计算两个集合的并和交的Rough隶属函数方法,它克服了前者利用Rough集理论计算Rough隶属函数的复杂性,而迎来了简单和高精度的特点。

In recent years,many approaches for handling approximate problems have been brough out.One of rough membership functions for union and interseection of Computing two sets using rough set theory is used to be more.But sometimes the values of computing are not very precision.So,we propose a way for computing rough membership functions of union and intersection of two sets in the paper.Which conguers the complexity of computing using rough set approach in the former,to bring the feallre of simplicaty and high precision in the latter.
