Twin approximation space and its application in analysing employee engagement and employee value proposition

Abstract

The concept of rough set was introduced by Pawlak is efficiently used in data analysis. In this paper, we have introduce twin rough set defined on a twin approximation space I = (U,A,B) where U is a non-empty finite set of objects and A and B are the two disjoint set of fuzzy attributes on the elements of U. This novel definition plays a vital role in comparing the influence of a set of attributes in A over that of B on the elements of U. Also, we have proposed an algorithm for this comparative analysis and the proposed algorithm is illustrated by taking a real time data. In this, a detailed analysis is done in comparing the two significant aspects namely employee engagement and employee value proposition of the employees in an organisation.
