Disaster relief distribution requires precise prioritization so that aid can be distributed effectively to affected areas. This study aims to design and build a Geographic Information System (GIS)-based Decision Support System (DSS) using the Analytical Hierarchy Process (AHP) method to determine the priority of disaster relief distribution in North Sumatra Province. This study uses a system development approach with a population of districts and cities in North Sumatra and a sample of three regions, namely Sibolga City, Central Tapanuli Regency, and South Tapanuli Regency. The research instruments include paired comparison questionnaires, spatial data, and documentation. Data analysis was carried out using AHP through criteria weighting calculations, consistency testing, and alternative rankings, while system functional testing used Blackbox Testing. The results showed that the number of affected victims had the highest weight of 0.5011, with a Consistency Ratio (CR) value of 0.0746. Central Tapanuli Regency received the first priority with a score of 0.3862, followed by Sibolga City with 0.3097 and South Tapanuli Regency with 0.3040. All tested features functioned according to the test scenarios. In conclusion, the integration of AHP and GIS produces a system that can support structured aid prioritization through multi-criteria calculations and digital map visualization.
