Objective:To explore how to choose the center locations to build the medical and health supplies reserve among many island towns.Methods:The center locations were selected from 18 towns Hainan Province,it's maximum service range(distance)was required to reach the minimum,or to minimize.Results:Three scenarios were considered,the center locations included only one town,two towns,three towns.By the use of graph theory and MATLAB programming,a mathematical model was established to obtain the shortest distance and the shortest path between arbitrary two towns.Conclusions:We find out the center sites under certain conditions,and determine the specific service ranges of the center sites.
Hainan is an island province in south China with a high frequency of unconventional emergencies due to its special geographic location and national military defense role.Given the limited transportation route from Hainan to the outside world,self-rescue is more important to Hainan Province than other provinces in China and it is therefore imperative to establish an independent, scientific as well as efficient provincal disaster medical system in Hainan.The regulatory role for vulnerability analysis/assessment has been demonstrated in establisment of disaster medical system in varoius countries and or regions.In this paper,we attempt to describe/propose how to adopt vulnerability assessment through mathematical modeling of major biophysical social vulnerability factors to establish an independent,scientific,effieicnt and comprehensive provincial disaster medical system in Hainan.
