Evaluation of the Criteria Affecting High-Speed Railway Operation Safety Using the Fuzzy AHP Method

Öz

In line with the increasing population, urbanization, and transportation demand in recent years, high-speed rail systems have been rapidly expanding worldwide as a sustainable, safe, speedy and high-capacity mode of transportation. Moreover, compared to other transportation modes, high-speed trains offer advantages such as energy efficiency, environmental friendliness, safety, and convenience for passengers, which further increases their attractiveness. For these reasons, the operation safety of high-speed railways is of great importance. Accordingly, the aim of this study is to identify the criteria affecting the safety of high-speed rail operations and to evaluate the relative importance of these criteria using the Fuzzy Analytical Hierarchy Method. Within the scope of the study, based on a literature review and expert opinions, three main criteria and twelve sub-criteria affecting high-speed rail operational safety were identified; subsequently, the weights of these criteria were calculated using the Fuzzy Analytical Hierarchy Method based on the evaluations of three experts. According to the results obtained, the most important main criterion is equipment, and the most important sub-criterion is the professional competence of personnel.

Yüksek Hızlı Demiryolu İşletim Emniyetini Etkileyen Kriterlerin Bulanık AHP Yöntemi ile Değerlendirilmesi

Öz

Son yıllarda artan nüfus, kentleşme ve ulaşım talebi doğrultusunda yüksek hızlı demiryolu sistemleri, sürdürülebilir, güvenli, hızlı ve yüksek kapasiteli bir ulaşım modu olarak dünya genelinde hızla yaygınlaşmaktadır. Ayrıca diğer ulaşım yöntemleriyle karşılaştırıldığında, yüksek hızlı trenlerin enerji tasarrufu, çevre dostu olma, güvenlik ve yolcular için kolaylık sağlaması gibi avantajlara sahip olması tercih edilebilirliğini arttırmaktadır. Bu sebeplerle yüksek hızlı demiryollarının işletim emniyeti oldukça önemli olmaktadır. Bu doğrultuda, bu çalışmanın amacı, yüksek hızlı demiryolu işletiminin emniyetini etkileyen kriterleri belirlemek ve bu kriterlerin göreli önem derecelerini Bulanık Analitik Hiyerarşi Yöntemi kullanarak değerlendirmektir. Çalışma kapsamında, literatür incelemesi ve uzman görüşleri doğrultusunda yüksek hızlı demiryolu işletim emniyetini etkileyen 3 ana ve 12 alt kriterler tanımlanmış; ardından 3 uzmanın görüşleri alınarak Bulanık Analitik Hiyerarşi Yöntemi ile bu kriterlerin ağırlıkları hesaplanmıştır. Elde edilen sonuçlara göre en önemli ana kriter ekipman ana kriteridir ve en önemli alt kriter personelin mesleki yeterliliği alt kriteridir.
