For figuring out the problem of DSm theory due to the conflict focal elements being added resulting in the computation complexity being more prominent, this paper proposes a method of approximate computation based on improved energy function. In this method, by adding a correction factor into the traditional energy function, the control rules of focal elements are improved, and by accepting or rejecting the focal elements properly, the computation is reduced effectively and the synthetic accuracy is guaranteed. By example analysis,it is shown that the proposed method takes on better effectiveness and rationality.
