Abstract

The multi-source reliability information fusion method based on D-S evidential theory is presented in this paper to solve the complex system reliability assessment problems. Aimed to the multi-source reliability information, the method in this paper established basic probability assignment firstly. Then, the reliability information is fused using D-S evidential theory. After that, the fused basic probability assignment is translated into a bet probability distribution function based on the pignistic probability transformation method. At last, the comprehensive reliability assessment is obtained.
