模糊证据理论及其在信息融合中的应用

为了使证据理论能更加有效地应用,把证据理论向模糊集推广,利用模糊集的隶属函数提出一种构造证据理论中的基本概率赋值函数的方法,实现了模糊理论和证据理论的有效结合。不但有效地解决了证据理论中的基本概率赋值函数的不易确定问题,而且由于证据理论应用于实际更加方便和有效,融合结果也更加合理。

Fuzzy Evidence Theory and Its Application in Information Fusion

This paper generalized the evidence theory and made it could be used in fuzzy sets in order to use it more effectively.With the fuzzy membership function,it presented a method to set up the basic probability assignment function(mass function) in evidence theory,and integrated fuzzy theory and evidence theory effectively.This method has two functions.First,it solves the establishment of the mass function,which is rather difficult in evidence theory.Second, it brings the evidence theory nearer to practice.So with this method,the application of the evidence theory is easier extraordinarily and the result of the combination is more reasonable.
