| Abstract | Space allocation of emergency centers which is dividing a territory into sub-areas based on specific criteria, is used for better management of emergency centers in disaster situations. Voronoi Diagram, as an influence area for each center can be used to specify service area of emergency centers. In standard Voronoi Diagram analysis, the only parameter used to define service area of each emergency center is Euclidian distance. Whereas in this paper, we develop a novel Network Voronoi diagram method to consider more parameters and improve space allocation of emergency centers. Accordingly, we consider capacity of center, service demands and network distance parameters. Also, resulting sub-areas of this method are both continuous and geospatially compact. In this method, distances are given by shortest path on the network. Dijkstra’s algorithm is developed to calculate shortest paths from centers at the same time. The result of the method is the partitioning of the nodes and the arcs of the network. By using this method, when emergency centers are contacted, an ambulance is sent to the location based on position of demand center and allocated space to emergency centers. Finally, as a case study, we applied the standard and network Voronoi diagrams in Tehran, capital of Iran. The results of this case study empirically show that the improved network Voronoi diagram can more precisely represent the service areas in urban regions than the corresponding Standard Voronoi diagrams. |
