(eng): The paper studies a possibility of transferring ideas of local computations introduced in probability by Lauritzen and Spiegelhalter into Dempster–Shafer theory of evidence. The paper recalls decomposable models, discusses connection of the model structure with the corresponding system of conditional independence relations, and shows that under special additional conditions, one can locally compute specific basic assignments which can be considered to be conditional.
