Improving performances in a company when collective strategy comes up against individual interests

In the current industrial context, strategies intended to bring about continuous improvement have to include the multi-criteria performance expression aspects. In complex systems, many actions may be envisaged to achieve the required levels of performance. A fuzzy representation is used to model the relationships between objectives and actions. Mostly, the potential improvement actions are distributed into several departments of a company. Then, the departments have to enter into negotiations to allocate actions‟ responsibility and share the budget granted by the direction. Lots of interest conflicts may occur. An argumentation framework is proposed to model this argumented negotiation for improvement design.
