ECLIPS is a European research project, partially funded by the European Commission in the context of its Research Framework Programme 6. Six partners participate in this research project: MÖBIUS (Belgium), EURODECISION (France), LoQutus (Belgium), the Technical University of RIGA (Latvia), Huntsman Advanced Materials (Germany), PLIVA-Lachema Diagnostika (Czech Republic). For more information about ECLIPS we recommend to visit the project web site www.eclipsproject.com. The overall goal of this project is to extend supply chain expertise to recent evolutions: globalisation, products diversification, and shortening of products life cycles. We consider that any life cycle can be divided into three phases: introduction, maturity and end-of-life. Three main issues are considered: Improve the statistical prediction of the demand at the beginning and at the end of a product life. Increase the profit during maturity phase by making cyclic the production at all levels of the process. From a pure mathematical point of view, Multi-Echelon Cyclic Planning induces an additional cost. However, simplification of production management and increase of the manufacturing efficiency should counterbalance this cost. More generally, to improve the whole life cycle management of products in supply chain, including switches between the three phases.
