Multi-echelon Inventory Planning for a One-Warehouse Multiple-Retailer Supply Chain

This paper studies a multi-echelon inventory replenishment problem based on a real-world case study. The aim of the study is to describe the problem, understand its underlying requirements and its specific features, and to build a corresponding mathematical model out of this. The paper presents an integer linear program that is proposed to describe the problem and capture its real-world specificities. Experiments are conducted on reduced instances drawn from the original data. These experiments measure the execution time using classical solvers and allow us to conclude on the relevance of such a solving approach for this particular case study.
