Some research on robustness of evidence theory

Evidence reasoning has good performance in dealing with uncertain information and is used in many fields. It is necessary to analyze its robustness. We first give the definition of robustness based on the aim of evidential theory and define a new concept conflict rate. Using the sectional conflict rate, we analyze the robust area of Dempster rule, weigh distribution and absorptive method. Finally, computer simulation indicates that two new rules are more robust than Dempster rule. Moreover, we give a robust area of Dempster rule according to general identification frame.
