연결성을 고려한 최대지역 커버문제를 활용한 재해구호 창고 최적위치 분석

초록

This study proposes a method to find the optimal locations of disaster relief warehouses, a sort of humanitarian logistics facilities to store disaster supplies such as a first-aid kit, bottled water or protective clothing. In the event of a disaster, necessary goods need to be distributed to as many people as possible from the disaster relief warehouses. Moreover, distance between two warehouses can be less than a predetermined length so that immediate supply will be possible in the case of stock out in one facility. Therefore, a connected maximum covering problem has been proposed in this study to cover the most demand in the case of an emergency with a set of connected facilities. A case study is conducted to investigate the location of additional disaster relief warehouse considering current operating system in South Korea. This study will be useful for decision makers or transportation planners in humanitarian logistics to reduce adverse impact of various disasters on the supply chain.
