• ARITHMETIC OPERATIONS OF FOCAL ELEMENTS AND THEIR CORRESPONDING BASIC PROBABILITY ASSIGNMENTS IN EVIDENCE THEORY

Abstract

Dempster-Shafer theory of evidence is a very important tool widely used in many fields such as Information Fusion and decision-making. In evidence theory when focal elements and their corresponding basic probability assignments (bpa) of variables are given then focal elements and their corresponding probability assignment (bpa) can be combined under arithmetic operation. In [5] authors proposed methods to combine fuzzy focal elements and their basic probability assignments of two variables. Here, we make further investigation for interval focal elements.
