Mathematical modeling for selecting center locations for medical and health supplies reserve in Hainan Province.
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.
