基于欧氏距离的基本信任函数确立方法

A method to establish mass function based on euclidean distance

声学故障检测与定位是维护舰船隐身的重要手段。为了实现对声学故障的检测与定位,开发了基于案例推理的专家系统。该系统采用D-S证据理论对案例推理结果进行信息融合。针对基本信任函数很难确定的问题,给出了一种基于样本间欧氏距离的信任分配函数确定方法。实验证明该方法具有较好的可行性。

Detecting and locating acoustic fault is an important process to maintain the stealthy of the warship, an expert system using case-based reasoning was developed to carry it out. D-S theory was introduced to fuse the information obtained through the process of case-based reasoning. A method based on euclidean distance between the samples to establish the mass function, which was difficult to obtain, was proposed. The experiment proved that the method is feasible.
