A mathematical model to optimize debris clearance problem in the disaster response phase: A case study

The post-disaster response phase aims to reduce casualties by accessing critical areas to transfer relief aid, search and rescue operations to the injured as soon as possible. Debris from the disaster blocks roads and prevents rescue teams from reaching critical areas. It is crucial to decide which routes should be cleared for relief aid transportation to reduce the negative effects of the disaster. In this study, a model for debris removal is presented to minimize access time to critical areas such as hospitals and maximize coverage of the areas. The AUGMECON 2 method has been used to solve this problem. Also, the efficiency of this solution method in Tehran has been studied, and its results have been analyzed. The results of this study indicate the importance of considering a comprehensive plan and several sites for debris removal in the disaster response phase.
