Are Alternatives to Dempster’s Rule of Combination Alternatives?
نویسنده
چکیده
In the latest issue of this journal, Lefevre et al.’s paper [1] raises the important question of how to combine belief functions from different sources and how to manage conflicts. They propose a parametrized combination rule that includes several existing combination rules as special cases. Their method is based on so-called weighting factors that determine how conflicting masses are to be distributed among the subsets of the corresponding frames of discernment. Since my understanding of Dempster-Shafer theory and my practical experience with belief function modelisation and corresponding computations is quite different, I do not support several points in their approach.

A Model for Decision Making with Missing, Imprecise, and Uncertain Evaluations of Multiple Criteria
In real-life multicriteria decision making (MCDM) problems, the evaluations against some criteria are often missing, inaccurate, and even uncertain, but the existing theories and models cannot handle such evaluations well. To address the issue, this paper extends the Dempster–Shafer (DS)/analytic hierarchy process (DS/AHP) approach of MCDM to handle three types of ambiguous evaluations: missing...
متن کاملDempster's Rule as Seen by Little Colored Balls
Dempster’s rule is traditionally interpreted as an operator for fusing belief functions. While there are different types of belief fusion, there has been considerable confusion regarding the exact type of operation that Dempster’s rule performs. Many alternative operators for belief fusion have been proposed, where some are based on the same fundamental principle as Dempster’s rule, and others ...
متن کاملMaximum Consistency Algorithms for Fusing Evidence
Random set theory together with Dempster-Shafer theory of belief functions provide a convenient way how to model uncertain information and how to project it through a function. This paper consists of two parts. In the first part I investigate few known algorithms for retrieving mass assignments from the coherent lower and upper probabilities, so that they can be approximated by random sets with...
متن کاملEmergency alternative evaluation under group decision makers: A method of incorporating DS/AHP with extended TOPSIS
How to select suitable emergency alternative is critical to emergency management and has attracted much attention for both researchers and practitioners. In the process of evaluating emergency alternative problems, there usually exists incomplete and uncertain information, and the decision makers can not easily express their judgments on the candiates with exact and crisp values. The Dempster–S...
متن کاملAn Improved Dempster-Shafer Algorithm Using a Partial Conflict Measurement
Multiple evidences based decision making is an important functionality for computers and robots. To combine multiple evidences, mathematical theory of evidence has been developed, and it involves the most vital part called Dempster’s rule of combination. The rule is used for combining multiple evidences. However, the combined result gives a counterintuitive conclusion when highly conflicting ev...
