Abstract The uncertain inference of D-S evidence theory can deal with the ambiguity and uncertainty of information issues. This paper aims for the effect of incomplete of the original parameters or the effect of subjective parameters in the reliability evaluation of distribution system. A D-S evidence inference method contacted with Bayesian networks for reliability evaluation of distribution system is presented．It constructs improved Bayesian networks model by means of belief functions, plausibility functions and multimode node models. This method resolves the influence of informative inadequacy and uncertainty, and makes a more rational evaluation result. It is proved to be available and valid through an example．
