Modelling Requirements in Service to PLM for Long Lived Products in the Nuclear Field

Part 2: Knowledge-Based ServicesInternational audienceRequirements engineering in usually considered a first step before design that is to evolve with each generation or version in a prod- uct line. Nuclear plants however, are subject to modifications during their lifetime, in their design and implementation as well as in the re- quirements they have to satisfy. Economic, technical and safety reasons lead to extending the requirements engineering process through the whole life-cycle of the nuclear plants. This article presents an ontology-based approach to integrating the requirements engineering into a PLM ap- proach for such long-lived, large-scale products
