Decision management system in a design process

The specifications, based on UML (Unified Modelling Language), of a software system allowing to preserve decisions in a product design process are presented. The current design process modelling tools propose some models to represent and to analyse the organization and activities. A great part of the model is becoming computer executable to make the formalization of the structure and the behaviour of enterprise components and operations possible in order to understand, analyse and optimise the design process. Considering a product design process as an operational, informational and decisional system, we propose to study and model the decision system. The aim of this paper is to show a system whose objective are to guarantee the cohesion between collected information, taken decisions and performed actions, and to preserve the various decision-makings ways (origins and consequences) whether they are successful or not. An application of this system in an industrial context is presented.
