Threat assessment based on entropy weight greyincidence and D-S theory of evidence
基于熵权灰色关联和D-S证据理论的威胁评估

By combining entropy weight grey incidence with D-S theory of evidence, this paper proposed a method of threat assessment to deal with the uncertain information of aerial threat target. It employed the theory of entropy to acquire the weights of different indices. Meanwhile, it determined uncertain degrees corresponding to different indices through the methodology of grey incidence. Subsequently, it obtained the Mass functions of different targets in different indices. It carried out the fusion of different Mass functions on the basis of D-S theory of evidence, sorted the targets according to the belief function value. A numerical example demonstrates that the aforementioned method is reasonable and effective.
