Exploitation de la demande prévisionnelle pour le pilotage des flux amont d'une chaîne logistique dédiée à la production de masse de produits fortement diversifiés

In this PhD dissertation, we investigated the way of exploiting the demand forecasts for the upstream flow management in a context of mass production of highly diverse products and of geographical dispersion of the production units. When the forecasts are poorly exploited, phenomena similar to the well-known bullwhip effect in the downstream supply chain appear in the upstream supply chain altering permanently its performances. In order to counter some of the mechanisms underlying these phenomena, we proposed an adaptation of the MRP to perform the exploitation of the forecasted demand. The adaptation of the MRP is based on a calculation method that uses the planning BOM for calculating and transmitting replenishment levels along the upstream supply chain. This approach has been successfully tested on several application studies in the automotive industry.
