The Robust Emergency Medical Facilities Location-Allocation Models under Uncertain Environment: A Hybrid Approach

In emergency medical facilities location, the hierarchical diagnosis and treatment system plays an obvious role in rational allocation of resources improving use efficiency resources. However, few studies have investigated operational mechanism systems uncertain environments. To address this research gap, paper proposes a hybrid approach for facilities’ location-allocation. first stage, order to concentrate on utilization resources, we choose alternative facility points from whole through entropy weight method (EWM). second uncertainty sets are used describe number patients at more accurately. We propose robust model configure large base hospitals based optimization method. Furthermore, proposed models applied management Huanggang City under COVID-19. The results show that optimal location-allocation scheme meets actual needs. Simultaneously, disturbance ratio level significant impact configuration scheme.
