Improving the robustness of a supply chain tactical plan

International audience; Based on linear and linear integer programming techniques, Advanced Planning Systems (APS) enable a tactical plan to be established each time the plan deviates from reality. Thus, planning is more reactive but may lead to a loss of robustness when making a decision. This article presents a specific approach to increase robustness and stability for tactical plans. Several methods have already been discussed to achieve this robustness target. This proposed new policy is called the "reference plan".
