MTSPC26 | Emergency storage centers in the Béni Mellal Khénifra region: location and management

#MTSPC #MTSPC26 #logistics #warehouse #transport #ENSA_Béni_Mellal #Mghilla #Morocco #mathcompetition #Oral_session #disastermanagement Faced with the recurring natural disasters that strike Morocco—the Al Haouz earthquake (magnitude 6.8; 2,960 victims; 2.8 million affected, September 2023), the floods in Safi and Ksar El Kébir (December 2025 – February 2026), and the winter isolation of more than 200 villages in the provinces of Béni Mellal, Azilal, and Khénifra—the Béni Mellal-Khénifra region suffers from a critical structural deficit in local logistics infrastructure. Response times are 48-96 hours due to the lack of decentralized warehouses, exposing 80,000 residents to life-threatening shortages. This work proposes a rigorous mathematical approach to determine the optimal number, location, and size of emergency storage centers in this region, based on real data from the RGPH 2024 (2,484 rural villages, 1,235,364 inhabitants spread over 17,555 km²). The problem is formulated as a Multi-Objective Capacitated Facility Location Problem (MO-CFLP), solved by the Gurobi solver via its Python API. The model simultaneously optimizes population-weighted distance, investment cost, and volumetric capacity, subject to constraints excluding risk zones (seismic, flood-prone, ecological, military), a maximum coverage of 100 km, a unique allocation of villages, and minimum capacity. Of 106 candidate sites selected after geospatial filtering (area ≥ 25 ha), four optimal centers were identified in the municipalities of Aït Abbas (Azilal), Aït Ishaq and Sbat Aït Rahou (Khénifra), and Ouled Youssef (Béni Mellal), ensuring comprehensive coverage of the 2,484 villages. A complete operational management model is also presented: internal architecture in four functional zones, Push/Cross-Docking flow strategies, last-mile optimization by VRP/TSP, and reverse logistics.
