| 摘 要： | 针对证据理论在实际应用中运算量大的问题,给出了Dempster融合规则的一种等效计算方法,并从理论上对该方法进行了证明。该方法首先计算未归一化的融合结果,然后把每一个未归一化的结果转化为与Dempster合成规则等效的结果,因此可以避免计算冲突系数,与Dempster合成规则相比可以减少计算量。最后用实例对该方法进行了验证。

| Abstract: | A new method which is identical to the Dempster fusion rule is presented to deal with the problem of the calculation burden ; and the method is proved in theory; In this method, the without normalized fusion result is calculated; and the result is transform to the Dempster fusion result. The new method could avoid the calculation of conflict coefficient, and it could reduce the calculation burden to compare with the Dempster fusion method. At last, an example is proposed to check this method. |
