P.L.M et gestion des évolutions de données techniques : impacts multiples et interchangeabilité restreinte

The principles and the modalities proposed by Product Lifecycle Management (P.L.M) to manage the technical data evolutions, are studied in the contexts of intensive renewal and creation of technical objects (innovation) with serial reproduction (serialization). The problem to manage multiple impacts on configurations has not been resolved on theoretical and practical plans yet. The attempts to conjugate the various functionalities offered by PLM lead in fact to irreconcilable choices, and the expected results must be relativized thereof. The conditions and the principles to automate the configurations evolutions management are redefined, in particular via a notion of restricted, relative and conditional interchangeability, and via a new naming of objects, able to identify their composition according to the configurations of uses. In fine, a typology of the possible formalisms to manage the configurations evolutions, according to the generic industrial situations conjugating in a variable way innovation and serialization, is proposed. Investigations were hold in industrial environment (aeronautics, automobile, endless fire industry) and in healthcare. The main P.L.M. solutions of the market have been examined.
