r criteria that need to be considered, including the distance to the location, the level of logistic needs, the number of personnel at the location, and the availability of logistics in the warehouse. Additionally, difficulties frequently arise in determining priority locations during emergencies or disasters, as well as vulnerabilities to subjective errors due to human limitations in analyzing complex data. Another issue is the unequal allocation of logistics, where some locations receive more logistics than needed, while others experience shortages. A Decision Support System (DSS) is a computer-based system designed to assist decision-makers in analyzing data, evaluating various alternatives, and providing recommendations. DSS aims to simplify the decision-making process to make it more effective. Various methods are used in the decision-making process, one of which is the Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) method. This system aims to reduce subjectivity, increase efficiency, and ensure a more equitable allocation of logistics based on needs. It is expected that this DSS can serve as a solution that facilitates faster, more accurate, and transparent decision-making.
