Abstract This study proposes a data-driven framework for mobile hospital deployment, addressing the limitations of current qualitative guidelines that are primarily focused on short-term responses. By analyzing the recovery duration of 117 disasters in Korea from 2014 to 2022, this research quantifies the temporal characteristics of disaster response. A 6th-order polynomial regression analysis on the recovery rate data identified a dynamic pattern with distinct inflection points empirically defining the boundaries between acute, subacute and chronic phases. Based on these findings, a four-phased deployment model?Phase A (0?2h), Phase B (2?72h), Phase C (72?1,488h), and Phase D (≥1,488h)?is proposed. The analysis identifies Phase B as the most critical period with the highest disaster occurrence(52.14%) and casualty rates (64.97%, excluding COVID-19) demanding a strategic concentration of advanced medical resources within this 2 to 72 hour time-frame. This time-based framework offers a quantitative foundation for enhancing national disaster response policies and provides a practical roadmap for the phased operation of rapid response mobile hospitals.
