Input: In this article we present two ways of struc­ turing bodies of evidence, which allow us to reduce the complexity of the operations usu­ ally performed in the framework of evidence theory. The first structure just partitions the focal elements in a body of evidence by their cardinality. With this structure we are able to reduce the complexity on the calculation of the belief functions Bel, PI, and Q. The other structure proposed here, the Hierarchi­ cal Trees, permits us to reduce the complex­ ity of the calculation of Bel, PI, and Q, as well as of the Dempster's rule of combination in relation to the brute-force algorithm. Both these structures do not require the generation of all the subsets of the reference domain.
