The applications of maximal covering model in Typhoon Emergency shelter Location Problem

Typhoon-induced disaster is one of the most important factors influencing the economic development in China. One facet of evacuation is the withdrawal or removal of persons from a stricken or threatened area. Another is the resettlement of the victims, or potential victims, and the provision of shelter and resources in the areas to which those residents are moved. Typhoon Emergency shelters are places for people to live temporarily when they can´t live in their previous residence during typhoon disasters. The most important function in emergency management is that choosing the positions of emergency service facilities, hence the site selection decision-making that how to effectively configure and rational distribution of typhoon emergency shelters in rural areas is very important. This paper describes an integrated location-distribution model for coordinating logistics support and evacuation operations in disaster response activities. In risk mitigation studies for natural disasters, possible sites where these units can be situated are specified according to risk based rural structural analysis. Logistics coordination in disasters involves the selection of sites that result in maximum coverage of resettlement need in affected areas. A example is given to show how the proposed model can be used to optimize the locations of typhoon emergency shelters in coastal typhoon disaster areas.
