Bipolar soft sets and rough sets are two different techniques to cope with uncertainty. A possible fusion of rough sets and bipolar soft sets is proposed by Karaaslan and Çağman. They introduced the notion of bipolar soft rough set. In this article, a new technique is being introduced to study roughness through bipolar soft sets. In this new technique of finding approximations of a set, flavour of both theories of bipolar soft set and rough set is retained. We call this new hybrid model modified rough bipolar soft set MRBS-set. Moreover, accuracy measure and roughness measure of modified rough bipolar soft sets are defined in MRBS-approximation space and its application in multi-criteria group decision making is presented.

改良的粗糙双极软套

双极软集和粗糙集是应对不确定性的两种不同技术。Karaaslan和Çağman提出了粗糙集和双极软集的可能融合。他们介绍了双极软粗糙集的概念。在本文中，正在引入一种新技术来通过双极软集研究粗糙度。在这种寻找集合近似值的新技术中，双极软集合和粗糙集合的理论都保留了风味。我们称这种新的混合模型修改的粗糙双极软集MRBS集。此外，在MRBS逼近空间中定义了改进的粗糙双极软集的精度度量和粗糙度度量，并提出了其在多准则群决策中的应用。
