<p>The invention relates to a method and system for standardizing data used for monitoring an aircraft engine (1) comprising: - means (5) for gathering in the course of time temporal measurements on said aircraft engine (1); - means (5) for calculating on the basis of said temporal measurements a set of indicators Y = (Yi,..., Yi...,Ym) specific to elements of said engine; - means (5) for identifying on the basis of said temporal measurements a set of exogenous data X = (*,,...,*") representative of the exterior context intervening on said set of indicators F; - means (5) for defining a conditional multidimensional model which simultaneously manages the indicators of said set of indicators F while taking account of said set of exogenous data X so as to form a set of estimators Y = (yi,..., y],..., ym) corresponding to said set of indicators Y = (y?,...,yi,...,yn); and - means (5) for normalizing each estimator y} as a function of a reference value of the corresponding indicator y} and of a deviation between said each estimator Yi} and said corresponding indicator y} so as to form a set of standardized values F = (~yi,..., ~yJ,...,~ym).</p> |
