Extensions and Applications of Evidence Theory
Although the Dempster-Shafer theory of evidence fits in handling both imprecision and uncertainty very effectively, a large amount of researches have shown its extensions to be needed. The belief function can not handle the issue of comparisons. The orthogonal sum indeed plays a main role in evidential reasoning, but it has been criticised when it is used for combining two largely conflicting pieces of evidence. Also, it can only be used to combine evidence coming from the same frame of discernment.
