Study on information fusion method of extenics-based D-S evidential theory

Making analysis on the theories of D-S evidential reasoning, rough sets and extenics sets, the three theory held comparability in defining uncertainty sets. It´s feasible to introduce the relevant theories and methods of extenics to information fusion and a method of extenics fusion (MEF) is presented as well. The method combines extenic correlation function with Dempster rule and is considered to be a good solution in solving evidence collision and BPA function in information fusion method basing on D-S evidential theory. The simulation test results show that MEF is better than the traditional D-S evidential theory and is applicable to all kinds of evaluation problems.
