Cui Jia-we · 2014
Aiming at the opening issues that indicators are ambiguous and threshold setting is too subjective in using the classical conflict coefficient to determine the applicability of the Dempster'scombination rule in D-S evidence theory,a new applicable condition of the Dempster's combination rule was proposed.Firstly,evidence conflict couldnot judge the application of the Dempster's combination rule.Secondly,the reason of the unreasonable results of using the Dempster's combination rule was analyzed.Thirdly,the condition was proposed.The results of the numerical examples and the comparison with the similar methods demonstrate that the proposed applicable condition is clear and simple,and provides a good applicable and reasonable indicator.
