Prioritizing Patients in the Aftermath of Mass Casualty Events Considering Different Resources
, M.Sc. Thesis Sharif University of Technology ; Shavandi, Hassan (Supervisor)
Abstract
In the aftermath of mass-casualty events, main resources may be overwhelmed by the sudden jump in demand. To ration these resources with considering the patients priority for help, mean triage. For prioritizing the patient for help, the limitation of resources should be considered. These resources can be different. This thesis at the first step investigates how the priority assignment can be done in a clearing system and what the potential benefits would be when there are same resources in the system. At the next step, the difference between resources is considered. So in this thesis, the problem of priority assignment of patients in an emergency system is modeled and analyzed at first with...
A multi-agent optimization formulation of earthquake disaster prevention and management
, Article European Journal of Operational Research ; Volume 229, Issue 1 , 2013 , Pages 261-275 ; 03772217 (ISSN) ; Poorzahedy, H ; Nassiri, H ; Nourinejad, M ; Sharif University of Technology

Abstract
Natural earthquake disasters are unprecedented incidents which take many lives as a consequence and cause major damages to lifeline infrastructures. Various agencies in a country are responsible for reducing such adverse impacts within specific budgets. These responsibilities range from before to after the incident, targeting one of the main phases of disaster management (mitigation, preparedness, and response). Use of OR in disaster management and coordination of its phases has been mostly ignored and highly recommended in former reviews. This paper presents a formulation to coordinate three main agencies and proposes a heuristic approach to solve the different introduced sub-problems. The...
Resiliency enhancement against wildfires

Abstract
The power system is the foundation for a modern society, and its safe and efficient operation is the prerequisite for our social and economic life. Manmade attacks and natural disasters such as hurricanes, tornadoes, floods, volcanic eruptions, and wildfires can cause temporary or permanent damages to the electric power system infrastructure. Wildfires are among the natural disasters rapidly growing in the last years. This has aroused growing attention toward the resiliency enhancement of power systems against wildfires. This paper reviews the activities developed to improve the resiliency of power systems, focusing on wildfires. In this regard, hardening and pre-event preparation,...
Pre-crisis Planning in Transportation Networks, Considering Immediate, Short-Run and Long-Run Losses: Case Study of the 2003 Bam Earthquake
, M.Sc. Thesis Sharif University of Technology ; Poorzahedy, Hossein (Supervisor)
Abstract
Natural disasters take many lives each year and leave many others homeless, thereby occupy governments to restore previous conditions rather than deal with progress. Iran has also a worrisome record of natural disasters, and the unpreparedness of the parties involved turn each of such event into a disaster. The purpose of this study is to estimate more accurately the outcomes of severe earthquakes, and show its effect on the decisions which are made to mitigate them. The losses are classified into three groups of immediate, short-run and long-run, which are then measured by some common quantities. Using the 2003 Bam Earthquake as a reference, these quantities are used to measure the...
Application of a Multi-agent Optimization Model in Pre-disaster Planning with Consideration of Overall Loss: Case of Bam 2003 Earthquake
, M.Sc. Thesis Sharif University of Technology ; Poorzahedy, Hossain (Supervisor)
Abstract
Earthquake is one of the deadliest natural hazards that has taken more than 400 thousand lives, only in the last decade. Iran is one of the countries that are at high risk of potential death toll resulting from such hazards, firstly because it is located in a potentially high-risk zone, the so-called earthquake belt and, secondly because of its problems in the management of disastrous situations (especially, pre-disaster management). Bam 2003 earthquake is one of the most painful experiences in this context. So, in this research, emphasizing on the practical use of optimization models, an existing model is applied on the damaged area of the Bam earthquake. The mentioned model considers the...
An effective approach for aid planning on multi-type transportation networks after a disaster

Abstract
We present a new approach for emergency response planning to the injured on a multi-type transportation network. We consider a three-type transportation network with separate connection links simultaneously: road, rail and air networks. In this study, a circle-based approach is presented where using concentric circles with various radiuses, different levels of the effect of a disaster are considered. After formulating the relations, we present an integer nonlinear programming model for the problem. The model is to determine the locations for establishment of temporary aid stations among the candidate locations, the type of aid stations, the percentage of the injured allocated to each...
Response planning for accidental oil spills in persian gulf: a decision support system (DSS) based on consequence modeling

Abstract
Different causes lead to accidental oil spills from fixed and mobile sources in the marine environment. Therefore, it is essential to have a systematic plan for mitigating oil spill consequences. In this research, a general DSS is proposed for passive and active response planning in Persian Gulf, before and after a spill. The DSS is based on NOAA's advanced oil spill model (GNOME), which is now linked with credible met-ocean datasets of CMEMS and ECMWF. The developed open-source tool converts the results of the Lagrangian oil spill model to quantitative parameters such as mean concentration and time of impact of oil. Using them, two new parameters, emergency response priority number (ERPN)...
