The methods of the fault diagnosis and degradations used in the different industrial sectors are various and consider the specifity of the materials forming their industrial processes. For some relatively simple processes, the relations between the causes and their effects are Biunivocal and the diagnosis with reverse reasoning is easy. Contrarily for the complexes processes, the situation is slightly different and is impossible to precede a deductive reasoning. The diagnosis is therefore only possible by using a different and a complementary knowledge. The sensitivity method for the detection and localization of the linear system defects is used in this paper.
