This is the data repository for manuscript "optimizing a multi-echelon location-inventory problem with joint replenishment: a Lipschitz ε-optimal approach using Lagrangian relaxation". The data repository contains all instances used in our study. The dataset consists in two folders. 1) The inputData folder contains all orginal data of numerical instances, 2) The outputData folder contains the solutions of instances. The data are all randomly generated and can be used publicly.
