Abstract
One of the open issues of Dempster Shafer theory is how to determine basic probability assignment function (BPA).To solve this problem
a method to determine BPA based on interval numbers is proposed in the paper.At first
the model of interval numbers is constructed with the samples.Then the distance of interval numbers is used to represent difference among the attributes of the samples
so the similarity of them is calculated.At last
the similarity is normalized to get the value of BPA.The effectiveness of this method is proved by classifying the Iris Set.It concludes that the total recognition rate is 96%.This method is simple and practical;it can determine BPA in the case of the little number of the samples.
