Using GRAIMOD for improving performance of multi-product companies

European economies have been deeply affected by different crises. The impact of the economic crisis on enterprises is now recognized by everybody. Enterprises are fighting to pull through the present situation and are seeking to be prepared for the post-crisis phase. Enterprises need to reorganize in order to be better adapted to this situation and to integrate new dimensions in their development. GRAI Methodology is one of the three main methodologies (with PERA and CIMOSA) for enterprise modelling. In this paper, the concepts of GRAIMOD a tool for supporting GRAI Methodology is presented. Then a zoom is made on an example related to multi-product companies for defining a reference model according to enterprises of this activity domain. For improving this enterprise performance, a multi-criteria analysis was used by combining quality, cost, lead time but also carbon management, social societal and environmental dimensions.
