In a growing transportation market, the optimization and organization of distribution networks have become an important issue for companies that are looking for improving the efficiency of their freight transport systems. In this context, the adoption of a collaboration strategy between various logistics actors can enhance the operational efficiency of the networks and reduce sustainability impacts. In this paper, we evaluate the economic, environmental and social benefits of the logistics collaboration using an integrated planning approach that simultaneously optimizes the inventory, location and routing decisions. Firstly, we propose and adapt a Mixed-Integer Linear Programming (MILP) model to design a collaborative and noncollaborative sustainable distribution network. Secondly, we examine one of the problems that can cause conflict between partners, namely the cost-sharing problem. Finally, we discuss a case study of a French distribution network. The obtained results show that collaboration in integrated planning can significantly reduce CO_2 emissions, logistics costs and accident rate.
