IET Blockchain, Volume 5, Issue 1, January/December 2025.We propose a blockchain‐based system to enhance cloud systems' resilience against distributed denial of service attacks. Our approach integrates a hierarchical risk‐based attack tolerance mechanism with smart contracts, dynamically estimating risks at local, cluster, and global levels using Dempster–Shafer theory. Simulations show improved availability,

Distribution‐Matched Imputation for Incomplete Data Evidential Classification
Electronics Letters, Volume 61, Issue 1, January/December 2025.This paper introduces a novel distribution‐matched imputation (DMI) method that leverages evidential reasoning to address classification challenges in datasets with missing values, optimizing weights to minimize the inconsistency between training and test sets.

The Combination of Paradoxical, Uncertain, and Imprecise Sources of Information based on DSmT and Neutro-Fuzzy Inference [PDF]
, 2004 The management and combination of uncertain, imprecise, fuzzy and even paradoxical or high conflicting sources of information has always been, and still remains today, of primal importance for the development of reliable modern information systems ...

Reliability Analysis Based on Aleatory and Epistemic Uncertainty Using Binary Decision Diagrams
International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.The development of a mathematical model is an important step in reliability analysis. However, initial data are often not clearly defined, and some necessary information about the system’s behavior may be missing. Most mathematical models in reliability analysis primarily address aleatory uncertainty.

Journal of Information Systems and InformaticsEarly life is a crucial window for recognizing children’s interests and talents that shape later development. This study implements and compares two reasoning algorithms—Certainty Factor (CF) and Dempster–Shafer Theory (DST)—within a rule-based expert ...

General combination rules for qualitative and quantitative beliefs [PDF]
, 2007 Martin and Osswald \cite{Martin07} have recently proposed many generalizations of combination rules on quantitative beliefs in order to manage the conflict and to consider the specificity of the responses of the experts.
