It uses information about the probabilities that expected input will be absent in order to determine the trustworthiness of the data used for controlling the distributed system; the main challenge is to take accord of the stochastic dependency between some of the inputs. This takes the form of a relational static analysis dealing with quantitative information. %G English %2 https://inria.hal.science/hal-01515243/document %2 https://inria.hal.science/hal-01515243/file/978-3-642-38592-6_18_Chapter.pdf %L hal-01515243 %U https://inria.hal.science/hal-01515243 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-WG %~ IFIP-TC6 %~ IFIP-WG6-1 %~ IFIP-FORTE %~ IFIP-DISCOTEC %~ IFIP-LNCS-7892
