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

ObjectiveTo explore how to choose the center locations to build the medical and health supplies reserve among many island towns.MethodsThe center locations were selected from 18 towns Hainan Province, it's maximum service range (distance) was required to reach the minimum, or to minimize.ResultsThree 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.ConclusionsWe find out the center sites under certain conditions, and determine the specific service ranges of the center sites.
