Title: Composition of Credal Sets via Polyhedral Geometry,
Abstract: Recently introduced composition operator for credal sets is an analogy of
such operators in probability, possibility, evidence and valuation-based
systems theories. It was designed to construct multidimensional models (in the
framework of credal sets) from a system of low- dimensional credal sets. In
this paper we study its potential from the computational point of view
utilizing methods of polyhedral geometry.
