Abstract Natural an‎d man-made disasters have always been among the most significant challenges facing human societies, an‎d the efficient management of humanitarian supply chains plays a crucial role in reducing damages an‎d casualties. This study presents an integrated model for the location of distribution centers, optimal allocation of resources, an‎d scheduling of aid distribution under crisis conditions. First, the concepts an‎d related literature on crisis management, humanitarian logistics, an‎d multi-objective optimization methods are reviewed. Then, using Grey System Theory an‎d a multi-objective decision-making (MCDM) approach, a model is proposed that simultaneously addresses objectives such as reducing response time, ensuring equitable distribution of supplies, optimizing transportation costs, an‎d increasing coverage during the golden hours of a crisis. The proposed model is solved using the Epsilon-Constraint Method an‎d weighted sum approaches to generate the Pareto front. Additionally, sensitivity analysis is conducted to assess the impact of parameter changes on the results. GAMS an‎d EXCEL software are employed for modeling an‎d solving the optimization problems, while Excel is used for data preparation an‎d results analysis. The implementation results indicate that the proposed hybrid approach can significantly reduce response time an‎d costs, while enabling more equitable an‎d efficient distribution of aid. Ultimately, the study offers practical solutions that can serve as an effective framework for relief organizations, governmental bodies, an‎d decision-makers in crisis management
