    Assignment of Support Province and Alternative Route Selection for Emergencies and Disasters: an Application in Kocaeli Province
    (Afet ve Acil Durum Yonetimi Baskanligi (AFAD), 2024) Altin, Beyza; Ozer, Buket; Guven, Emel; Eren, Tamer
    In disasters, people experience great material and spiritual losses. After the disaster, it is seen that there is great damage to the transportation roads and transportation to the disaster area becomes difficult. By looking at the rapid delivery of aid to disaster victims in the disaster area with a solution-oriented approach, the complexity in transportation should be avoided by going to the region through different and safe routes. In this study, the problem of alternative route selection and support province assignment in transportation to the post-disaster region for the Darica district of Kocaeli province is discussed. This problem has been evaluated within the scope of the worst earthquake scenario in Kocaeli Provincial Disaster Risk Reduction Plan-IRAP 2021. The provinces assigned in the selected earthquake scenario were evaluated and new support provinces were listed, taking into account the situations in which they may be inadequate. It is aimed to determine alternative routes according to the listed support provinces. In this study, AHP (Analytic Hierarchy Process), PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation), TOPSIS (Technique For Order Preference By Similarity To An Ideal Solution), which are among the Multi-Criteria Decision Making (MCDM) methods, are used. © 2024 Afet ve Acil Durum Yonetimi Baskanligi (AFAD).

    Evaluation of natech criteria in organized industrial zones: An application for Kirikkale province
    (Elsevier Sci Ltd, 2024) Guven, Emel; Pinarbasi, Mehmet; Alakas, Haci Mehmet; Eren, Tamer
    Natural disasters are unexpected natural events that cause severe property loss and moral damage. T & uuml;rkiye has been exposed to many disasters due to its location. One of the disasters experienced is the Kahramanmaras , earthquake that occurred on February 6th, 2023, in the recent past. Two consecutive earthquakes caused significant loss of life and property. In addition, some technological accidents happened because of the earthquake. The biggest of these was the fire in the Iskenderun marina. After the earthquake, the big fire that started with the fire of the containers on the quay could be brought under control after a long effort and time. Although it is often overshadowed by natural disasters, technological accidents triggered by natural disasters (Natech) accidents can cause severe damage. Especially Organized Industrial Zones (OIZ) are in areas with high Natech risk. This study determined 10 criteria that will cause Natech accidents for OIZs by literature review. The Pythagorean Fuzzy Analytical Hierarchy Process (PFAHP) method is used to weight the criteria. Then, a ranking is made using The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method among the five sectors operating in Kirikkale OIZ and which may have Natech risk.

    Ranking of sectors in organized industrial zones according to Natech risk criteria: An application for Gaziantep province in Türkiye
    (Elsevier Sci Ltd, 2024) Guven, Emel; Pinarbasi, Mehmet; Alakas, Haci Mehmet; Eren, Tamer
    Technological accidents triggered by natural disasters are called Natech accidents. Natech accidents have the impact of increasing the negative effects of disasters. One of the places at risk for a Natech accident is the Organized Industrial Zones (OIZs), where many industrial establishments are located. Although businesses within OIZs are evaluated in terms of security, Natech risk assessment is often ignored. This situation causes Natech accidents to occur. For these reasons, the study focused on evaluating OIZs regarding Natech risk. Many criteria such as electrical resources, natural gas, distance between buildings and so forth are taken into account in Natech's risk assessment. However, it is challenging to make clear decisions and predictions about these criteria due to the nature of the disaster. There is inherently uncertainty and confusion during and after a disaster. For this reason, using fuzzy sets to evaluate criteria is more appropriate. Therefore, the study uses Pythagorean fuzzy sets, which have a wider fuzzy evaluation area. This study also includes the evaluation of alternative sectors in terms of Natech risk. For this purpose, Pythagorean Fuzzy Analytic Hierarchy Process (PFAHP) and Pythagorean Fuzzy the Technique for Order of Preference by Similarity to Ideal Solution (PFTOPSIS) methods are used. OIZ in Gaziantep has the largest area compared to those in other cities in T & uuml;rkiye, is chosen as the application area of the study. As a result of the study, it is determined that the release of hazardous substances and flammable criteria is the most crucial criterion, and the most dangerous sector in terms of Natech risk is the chemical sector.
