This article investigates the potential economic, environmental, and social effects of combining depot location and vehicle routing decisions in urban road freight transportation under horizontal collaboration. We consider a city in which several suppliers decide to joint deliveries to their customers and goods are delivered via intermediate depots. We study a transportation optimization problem from the perspective of sustainability development. This quantitative approach is based on three-objective mathematical model for strategic, tactical, and operational decision-making as a two-echelon location routing problem (2E-LRP). The objectives are to minimize cost and CO2 emissions of the transportation and maximize the created job opportunities. The model was solved with the ε-constraint method using extended known instances reflecting the real distribution in urban area to evaluate several goods’ delivery strategies. The obtained results by comparing collaborative and noncollaborative scenarios show that collaboration leads to a reduction in CO2 emissions, transportation cost, used vehicles, and travelled distances in addition to the improvement of the vehicles load rate but collaboration affects negatively social impact. To evaluate the effect of the method used to allocate the total gains to the different partners, we suggest to decision makers a comparison between well-known allocation methods.

The evolution of technology and the structural changes in the global economy had led the organizations to recreate their value chain and to allocate more resources to information system. The companies wishing to integrate distribution networks into their logistic system are turning to the EDI (the Electronic Data Interchange) which can extend the management of their physical value chain till the point of consumption of their product. The EDI provides a concordance between the physical flow and the information flow to enable the supply chain management to be effective and fast. This technology allow illustrating the role of Information Technology in the Supply Chain: without information system, the global supply chain cannot be efficient. Furthermore, Morocco is the first automaker in North Africa and the second in the African continent. This country is now recognized as industrial platform for the production and export in the automotive industry. This Morocco's position on the global value chain led us to conduct this study which aims to explore the practice of EDI in the automotive sector and its impact on the supply chain management.
