We prove that the proposed definition preserves all the necessary properties of the operator enabling us to define compositional models as an efficient tool for multidimensional models representation. Theoretical results are accompanied by numerous illustrative examples. cav_un_auth*0292247 Eighth International Symposium on Imprecise Probability: Theories adn Applications Compiegne 02.07.2013-05.07.2013 FR 2014 BA 1 PR RVO:67985556 http://hdl.handle.net/11104/0222595 2013 cav_un_epca*0394014 Proceedings of the Eighth International Symposium on Imprecise Probability: Theories adn Applications 978-2-913923-35-5 355 364 Compiegne Society for Imprecise Probability: Theories and Applications 2013
