The paper deals with the use of a UML approach for the specifications of a PDM system (product data management) implementation. A PDM system enables the management of the whole product data and related information about its entire lifecycle.The main goal of this paper is to highlight the added value of using an object-oriented approach for modelling, specifying and implementing a PDM system on a business case study. The chosen object-oriented approach and the used UML diagrams for the modelling and integration of product, process, and resource data is detailed for a turboprop aircraft project. #
One of the objectives of concurrent engineering has been to integrate more and more knowledge as soon as possible during the product development process. In such a method and owing to designer creativity, new design solutions are carried out. Design alternatives then appear; the differences can be relative to the functions, the technology, the materials or the manufacturing process as well. This paper presents some first specifications in modelling those design alternatives. Much more design solutions can then be kept in designers’ mind instead of focusing on the a priori best solution. The final solution is therefore chosen depending on every point of view involved in the design process. First of all this work aimed at defining the new knowledge that have to be taken into account in the product modelling in order to support the design alternatives management. Those new model elements must currently be integrated or linked with already-known product and design process models. The alternatives modelling has secondly been tested on very simple design examples. Afterwards, the design of a surgical simulator has been carried out that pointed out the real benefits and the feasibility of the alternatives modelling.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
