Can Evidence Be Combined in the Dempster-Shafer Theory
CoRR, 1988 Dempster's rule of combination has been the most controversial part of the Dempster-Shafer (D-S) theory. In particular, Zadeh has reached a conjecture on the noncombinability of evidence from a relational model of the D-S theory. In this paper, we will describe another relational model where D-S masses are represented as conditional granular ...

Navigation risk assessment scheme based on fuzzy Dempster–Shafer evidence theory
International Journal of Advanced Robotic Systems, 2018 In order to reduce the influence of subjective factors on navigation risk assessment, we present a novel scheme based on the fuzzy Dempster–Shafer evidence theory in this article.

Updating the Evidence in the Dempster-Shafer Theory.
Informatica, 1999 An algorithm for updating the evidence in the Dempster-Shafer theory is presented. The algorithm is based on an idea of indices. These indices are used to code the process of reasoning under uncertainty (the combination of evidence)using the Dempster-Shafer theory.

Algebraic structures related to Dempster-Shafer theory [PDF]
, 1995 There are described some algebraic structures on a space of belief functions on a two-element frame, namely so called Dempster's semigroup (with Dempster's operation ⊕), dempsteroids, and their basic properties. The present paper is devoted to the investigation of automorphisms of Dempster's semigroup.

The Dempster-Shafer Theory of Evidence [PDF]
, 2001 The Dempster-Shafer theory of evidence (here, DS theory, for brevity), sometimes called evidential reasoning (cf. Lowrance et al. [Lowrance et al., 1981]) or belief function theory, is a mechanism formalised by Shafer ([Shafer, 1976]) for representing and reasoning with uncertain, imprecise and incomplete information. It is based on Dempster’s original

A new conflict management method in Dempster–Shafer theory
International Journal of Distributed Sensor Networks, 2017 Conflict management is a hot research topic in Dempster–Shafer theory which is used to avoid the counterintuition problem of combination results. In the present conflict management methods, conflicting evidence is assigned to smaller weight to reduce its
