A Belief Coulomb Force in D-S Evidence Theory

Dempster-Shafer (D-S) evidence theory is regarded as an effective method of dealing with the uncertainty information but still suffers from conflict problem among evidence. Despite that various techniques were presented in plenty publications, currently, there no convincing and firm conclusion about optimum solution. This study presents Belief Coulomb Force (BCF) into D-S theory, where Zhou et al. entropy applied to represent electrical charge belief function, gravity or repulsion would be identified Pearson correlation coefficient. According simulation results, recognition accuracy on malfunction diagnosis approach reaches 93.7%, effectiveness analyzing can demonstrated comparison previous methods.
