Natural or human-inflicted disasters may cause large-scale disruptions in the services of infrastructure networks including power, water, and telecommunication. Restoring the services of these infrastructures is vital in the aftermath of the disaster, so that search-and-rescue activities, relief transportation, and restoration efforts can be efficiently facilitated. On the other hand, operations of these infrastructures may depend on receiving services from one another, resulting in an interdependent network structure. Consequently, addressing the decisions of network reinforcement before the disaster and the repairs in its aftermath needs to take into account this interdependent structure, as well as the uncertainties arising from the timing, location, and magnitude of the disaster. This paper introduces the Stochastic Interdependent Infrastructure Reinforcement and Repair Problem, which considers the pre-disaster reinforcement of interdependent network components and post-disaster repair scheduling in an integrated manner. In making these decisions, the uncertainty on which network components will be disrupted is incorporated into the problem definition. The problem is modeled using scenario-based two-stage stochastic programming. A heuristic based on a genetic algorithm and partial optimization is proposed to solve realistically-sized instances of the problem. Computational experiments not only show that the heuristic is able to find near-optimal solutions within reasonable times, but also illustrate the ability of the approach to help derive managerial insights.

Management of interdependent infrastructure networks under disaster-related uncertainties
Canbilen, Tuğçe; Batun, Sakine; Çelik, Melih; Department of Industrial Engineering (2020-8)
During a disaster, multiple infrastructures such as power, water, or telecommunications networks may face disruptions in their services. Services of these infrastructures are vital in the aftermath of a disaster to facilitate search-and-rescue activities, relief transportation, and restoration efforts. Furthermore, the operations of these infrastructures may depend on receiving services from others, resulting in an interdependent network structure. In the aftermath of a disaster, damages on the network segm...
Dynamic allocation of renewable energy through a stochastic knapsack problem formulation for an access point on the move /
Ceran, Elif Tuğçe; Uysal Bıyıkoğlu, Elif; Department of Electrical and Electronics Engineering (2014)
The problem studied in this thesis has been motivated by recent industry efforts toward providing Internet service in areas of the world devoid of regular telecommunications infrastructure via flying or floating platforms in the lower stratosphere. According to the abstraction in the thesis, the Access Point on the Move (APOM) having a renewable energy supply feature (solar, wind, etc.) must judiciously allocate this resource to provide service to users that demand service from it while it moves over an are...
Development of a GIS software for evaluating network relibility of lifelines under seismic hazard
Oduncuoğlu, Lütfi; Düzgün, H. Şebnem; Kestel, Sevtap Ayşe; Department of Geodetic and Geographical Information Technologies (2010)
Lifelines are vital networks and it is important that those networks are still be functional after major natural disasters such as earthquakes. The goal of this study is to develop a GIS software for evaluating network reliability of lifelines under seismic hazard. In this study, GIS, statistics and facility management is used together and a GIS software module, which constructs GIS based reliability maps of lifeline networks, is developed by using geoTools. Developed GIS module imports seismic hazard and l...
Pre-Positioning Disaster Response Facilities and Relief Items
RENKLİ, Cigdem; Duran, Serhan (2015-07-04)
Large-scale disasters cause enormous damage to people living in the affected areas. Providing relief quickly to the affected is a critical issue in recovering the effects of a disaster. Pre-disaster planning has an important role on reducing the arrival time of relief items to the affected areas and efficiently allocating them. In this study, a mixed integer programming model is proposed in order to pre-position warehouses throughout a potential affected area and determine the amount of relief items to be h...
ANALYZING THE RELATIONSHIP BETWEEN DISASTER RISK MITIGATION AND URBAN PLANNING PROCESSES: THE CASE STUDY OF ESKISEHIR CITY
Sert Özkiremitçi, Merve; Balaban, Osman; Department of City and Regional Planning (2022-5-11)
The aim of this study is to discuss the effectiveness and efficiency of urban planning in reducing the risk of natural disasters in cities and to analyse the relationship between planning and disaster mitigation processes. The study focuses particularly on the analysis of Eskişehir case with reference to data and information on disaster risk analysis, existing urban development plans as well as the plan implementation processes. After the 1999 Gölcük and Düzce Earthquakes, Eskişehir has also faced and to a ...
