Spatial Operational Research and its Application in Emergency Services
by Prof. LI Xiang Professor,East China Normal University
Abstract:
The potential of GIS has been integrated into operational research to facilitate optimally solving problems involving spatial data.In this presentation,some exam ples in emergency services are given, and a series of algorithms for making evacuation plans are introduced in detail. During a large-scale evacuation in response to extreme disasters, limited traffic infrastructure is often inadequate to entertain extremely large traffic volume generated within a short period, and a simultaneous evacuation accompanied with spontaneous behaviors can lead to disorder and conflict and seriously prolong the process. A pre-defined staged evacuation planis, therefore, required. This paper presents a method to facilitate making such a plan. Through employing an algorithm to schedule the departure time of each evacuation group, the method can guarantee that the time of completing large-scale evacuation is very close to its theoretically shortest evacuation time. Additionally, a few more efforts have been made to extend its application to groups with various speeds, to multiple exits, and to indoor space.
