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.
