This research focuses on methodological evaluation through a model that includes input factors and contextual variables. The findings indicate that a 10% increase in budget allocation correlates with an average 5.2% yield improvement, highlighting the effectiveness of financial investments. The study contributes to policy-making by providing a robust framework for assessing infrastructure performance using multile
