A Study of Ambulance Service Stations Allocation for Regional Integrated Management

Abstract

Local governments have recently been required to reduce the number of ambulance stations because of financial shortage and cost increase by improving their service level. We make a p-median public facilty location model for ambulance services and calculate it in our study area in Ehime prefectare. The results shows that we can reduce 3 stations of current 19 stations according to over all average service level criterion but some areas suffer from service decreasing. We can reduce one station when we add a constraint that every area should not suffer from less than 20% service decrease.
