• Abstract: The increasing frequency of disasters highlights the critical need for efficient and adaptable humanitarian logistics systems. To enhance decision-making in these complex environments, it is essential to incorporate advanced mathematical models through the development of Decision Support Systems (DSS). This study presents the development of a DSS prototype aimed at optimizing the location of temporary Points of Distribution (PODs) following a large-scale earthquake scenario in Alto Selva Alegre, Arequipa, Peru. The system distinguishes between two types of PODs: fixed PODs, which remain operational throughout all periods and serve as stable infrastructure during both the response and recovery phases, and temporary PODs, which are activated only during the initial response to maximize proximity to the affected population. The DSS is composed of four core components—a database, an optimization model, a user interface, and a communication layer and is structured into five interactive tabs. The Data tab presents input information; Optimization tab enables model execution and parameter adjustments based on decision-maker knowledge, resource availability, or operational priorities; Solution visualizes results by period; and Comparative allows users to analyze, and contrast saved configurations. Results show that small changes in input parameters such as the number of modules or active PODs can lead to significant improvements in coverage and travel distance, with only modest increases in cost. The DSS also adapts well to operational constraints, providing feasible solutions even when some sites are unavailable. By combining mathematical modelling with interactive usability, it supports quick scenario comparison and informed decision-making, offering a practical tool for humanitarian logistics planning.
