Locating Humanitarian Relief Effort Facility Using P-Center Method

The impact of climate change and global warming is more obvious. Extreme weather is more apparent. Thailand encounters with tropical storm or typhoon every year since Thailand is located between two oceans, India Ocean and Pacific Ocean. Southern part of Thailand is area prone to flash flood, flood, and landslide. The relief effort is needed to prepare in advance including Pre and Post-disaster because the medical supplies should be in hand of the victim as soon as possible. The focus of this paper is to investigate mathematical model to locate the right location of humanitarian relief effort facility so as to minimize the maximum traveling distance or time to victims. P-center model is used as a preliminary model to find the suitable locations. Districts in Nakhon Sri Thammarat and Phatthalung provinces are investigated for the right location of relief effort facilities.
