摘要
进行异类源数据融合时,经常会遇到证据冲突的情况,此时应用经典D-S证据理论进行信息融合,通常会出现有悖常理的现象。提出了一种新的证据合成方法,该方法根据各证据之间的相似度确定证据的权重系数,通过加权的方法进行证据合成,从而有效地解决了证据冲突时的信息融合问题。计算机仿真表明,这种方法是非常有效的。
There is always evidence conflict of heterogeneous sources data fusion. In this case, counter-intuitive behaviors often happen in the process of data fusion based on D-S evidence theory. In this paper, a new combination rule is proposed. First the weight coefficient is defined according to the evidence conflict factor, and then the evidences combine based on the weighted coefficients. The computer simulations show that the proposed method is effective to the data fusion of conflict evidences.
