Demiryolu hat geometrisi bozulmasının bilgi sistemler destekli modellenmesi

Bu çalışmanın ana amacı, demiryolu hat geometrisi bozulmasını modellemek ve elde edilen modeli daha etkin ve verimli bir demiryolu hat bakım-yenileme yönetimi sağlamak için CBS ortamında çalıştırmaktır. Bu çalışmada Türkiye Cumhuriyeti Devlet Demiryolları, veri tabanı oluşturmak ve analizler yapmak için CBS ortamına aktarılmıştır. Yaklaşık 180 km uzunluğunda ki demiryolu hattı analiz kesimlerine bölünmüştür. Göz önüne alınan her bir analiz kesimi en küçük temel uzunluğa sahiptir. Her bir temel analiz kesimi için, mümkün olan tüm genel hat verisi sağlanmıştır. Çok değişkenli istatistik analiz yapılarak hat geometrisi parametrelerinin katsayıları tahmin edilmiş ve sonuçlar verimli hat bakım-yenileme yönetimi sağlamak için CBS ortamına aktarılmıştır.

Modeling raillway track geometry deterioration: Information systems based study

Geographic Information Systems (GIS) has been proving its capability as a powerful management system in railways. Currently, there are many studies focused on the way to enhancing existing GIS approaches to enable the complete range of capabilities needed in railways research and management. Costs of permanent way and its M&R are substantial and form a large part of the total infrastructure expenditure. Any reduction of these costs has a significant impact on the overall efficiency of the management of infrastructure. The process of determining whether, when, where and how to intervene and deciding on an optimum allocation of resources and minimizing the cost is a very complex problem. The main goal of this study is to model track geometry deterioration and to operate the deterioration model on GIS environment for efficient railway track maintenance and renewal management. In this study, Turkish State Railways were transferred into GIS environment to develop database and to realize analysis. A model length of about 180 kilometers was divided into analyses segments. The length of the individual analyses segments considered was the minimum basic length. For each basic analyses segment, the general information was provided as far as possible. Multivariate statistical analysis was performed to estimate the coefficients of track geometry parameters and the findings were transferred into GIS environment for efficient track maintenance and renewal management.
