D-S 证据理论应用中的一种图解方法

D-S证据理论是对概率论的进一步扩充,在多传感器数据融合中,有着广泛的应用.当利用D-S合成公式进行融合时,由于需计算的项数较多且不易直接判定具体该有哪些项,容易造成漏项或错项,引起计算错误.提出了一种直观、简单的图解法,可使需计算的项一目了然.

A Graphic Method in D-S Proof Theory Application

D-S proof theory is an expansion to probability theory who has an extensive application in multi-sensor data fusion. But when the data are fused by D-S fusion formula, it is easy to get the error result caused by some missing items or error items. All of that because of there are too many items need to be computed which are difficult to determinate directly in the D-S fusion formula. The article proposes an intuitionistic and simple Graphic Method which can help you to find the necessary items at a glance.
