A Study on the Location of the Disaster Prevention Stockpile Center: The Case of the Disaster Logistics System in Gyeongsangbuk-do

Purpose – Gyeongsangbuk-do is a region prone to frequent natural disasters, and there are high expectations for the establishment of an Integrated National Management System of Disaster Resources. For this purpose, it is necessary to expand disaster prevention stockpiles in the province. However, currently, the logistics perspective has not adequately been considered, leading to network inefficiency. Therefore, this study proposes an optimal location-allocation plan for disaster stockpile warehouses in Gyeongsangbuk-do. Design/Methodology/Approach – This research applied a discrete-linear facility location problem based on maximal covering location algorithm. The optimal location is determined by prioritizing nearby areas and setting the service distance limit lower than the current maximum service distance. Findings – As a result, Gyeongju-si was identified as a more suitable facility location instead of Pohangsi, one of the current disaster stockpile center locations. Furthermore, the proposed optimal locationallocation plan is more efficient than the current network and reduces regional deviations due to the objective function of the applied algorithm. Research Implications – Based on the Integrated National Management System of Disaster Resources plan, this study holds potential for practical use by using the current operating warehouse locations in Gyeongsangbuk-do as parameters. Additionally, since logistics is often overlooked in disaster management, the optimal location and distribution plan proposed in this study can serve as an indicator of logistics efficiency.
