Disasters may have devastating effect on human life as well as economy, and Turkey is a disaster prone country, especially to earthquakes. This study aims to propose a multi-echelon humanitarian logistics network design by incorporation of demand uncertainty and road-facility vulnerabilities with an application to a possible earthquake scenario in Istanbul region of Turkey. In frame of the study, a two stage stochastic programming model is formulated. In the first stage, warehouse and distribution center locations as well as inventory pre-positioning decisions are made, whereas in the second stage, relief distribution decisions are made. The stochastic model considers different demand scenarios and also road and facility vulnerabilities are incorporated as discrete binary scenario sets into the baseline model. The model is executed under efficiency and equity based objective functions, to analyze the effect of different objective measures to model key performance measures. Sample average approximation heuristic method is utilized for the solution of the proposed mathematical model. A sensitivity analysis is conducted on the baseline model to see the effect of vulnerability as well as other parameters such as budget and facility capabilities on the results and model key performance measures.

Pre-positioning disaster response facilities and relief items considering probabilistic constraints : a case study on istanbul region Renkli, Çiğdem; Duran, Serhan; Department of Industrial Engineering (2013) Large-scale disasters cause enormous damage to people living at the aff ected areas. Providing relief quickly to the aff ected is a critical issue in recovering the eff ects of a disaster. Predisaster planning has an important role on reducing the arrival time of relief items to the a ffected areas and effi ciently allocating the them. In this study, an MIP model is proposed in order to pre-position warehouses throughout an a ffected area and determine the amount of relief items to be held in those warehous...
Flood forecasting and analysis within the Ulus Basin, Turkey, using geographic information systems Usul, Nurunnisa; Turan, Burak (Springer Science and Business Media LLC, 2006-10-01) Floods have been the most severe natural disasters in the West Black Sea Region of Turkey for many years; therefore Ulus Basin is selected as a study area for a thorough hydrologic flood analysis. The lack of embankments around the Ulus River and careless changes to the riverbed made by villagers, resulted in major flood events in the basin, causing significant damage in the area. In this study, the hydrodynamic characteristics of the basin and the riverbed are determined by calibrating the hydraulic module...
Analysis of existing building stock according to mitigation plan objectives Hasdemir, Berna; Balamir, Murat; Department of City and Regional Planning (2010) Earthquakes in Turkey, among all natural disasters claim the highest losses in terms of human lives, material and economic assets. Most of the lives are lost within the collapsed buildings, and most of the material and economic losses are again directly related to the functional capacities of the building stock. The method of risk assessment in the existing building stock is therefore an essential step in the maintenance of safer urban environments. Analysis of risks in the building stock is usually claimed...
Seismic Protection of Museum Collections: Lessons Learned After the 1999 Earthquakes in Turkey Ertürk, Nevra (Middle East Technical University, Faculty of Architecture, 2012-6-1) Turkey has a long history of large earthquakes in three major fault zones that place two-thirds of the country. Following the two major earthquakes that struck the nortwestern part of Turkey in 1999, several attempts have been taken at hospitals, schools or administrative buildings. The two earthquakes prompted museum professionals and policymakers to consider measures to protect museum collections as well as buildings against earthquake. After the 1999 earthquakes, various projects, scientific researches, ...
The effect of disasters on development: Van and Bingol case studies Gül, Tuğba; Başbuğ Erkan, Berna Burçak; Şenol Balaban, Meltem; Department of Earthquake Studies (2014) The increase of the number of natural, technological and man-made disasters and economic losses due to disasters caused an increase in significance of the studies that investigate the relationship between disaster and development. Turkey has actualized many studies after the 1999 Marmara Earthquake, however, the focus of disaster policies are still concentrated on response and reconstruction/recovery stages of disaster. 2003 Bingöl and 2011 Van earthquakes showed that disasters still cause economic burden o...
