    • The invention relates to a method for optimizing the tolerancing of a set of flexible parts, said parts being particularly subjected to forces. The method that is the subject of the invention enables the definition, at the design phase, of an optimum tolerancing for flexible parts according to the assembly process plan thereof and according to the desired functional requirements. Said method considers that structural digital models (201, 202) are parts to be assembled. Said digital models (201, 202) are composed of the following information: - a plurality of points referred to as assembly points (220); - a plurality of points referred to as structural points (230); - mathematical relations, known as mechanical stiffness, such as a non-null relative displacement of a structural point (230) or an assembly point (220) in relation to the other structural or assembly points in a single digital model, modify a tensor in each of these points. From a mechanical point of view, these mathematical relations express the existence of an elastic recovery property between the points (220, 230) that make up the digital model (201, 202). The issue of optimization is simplified by: the definition of influence factors; the simulation of parts deviating from the nominal by a distortion vector.
