This work project results from a challenge proposed by Jerónimo Martins, the largest food distribution group in Portugal, which consists in developing a simulator to support the centralization decision in Recheio, a cash & carry chain. A quantitative analysis was performed to understand the dispersion of purchasing volume by region and centralization degree. The simulator designed intends to acknowledge the impact of a specific decision on three dimensions: economic, environmental and social. The economic costs, CO2 emissions and stock-out probabilities, are presented for both centralized and decentralized scenarios. In the end, this project aims to optimize the company’s logistics chain
