Abstract

Benchmarking is frequently used in strategic management, while it may not be possible to compare companies such as Turkish Railways (TCDD) with their competitors due to unique structures. In such cases, the dynamic data envelopment analysis method, which is based on the ratio of outputs to inputs with the company's long-term data, can be used. One of the advances in data envelopment analysis in recent years is the ability to include undesired outputs. While determining the best practice, undesirable factors as railway accidents should also be considered for performance evaluation. To my knowledge, there is no study considering accidents in railway performance evaluation. In this context, this study aims to evaluate the performance of railways with 17-year data of TCDD, considering railway accidents, which are undesirable outputs for railways. In this way, it is aimed to contribute to the railway performance evaluation literature by adding undesirable outputs. The total length (km) and the number of personnel are inputs, the total number of passengers and the total freight are desired outputs, and the number of railway accidents is undesired output. The findings show that the best practice example for TCDD is 2013. The findings suggest that practitioners and decision makers should consider undesirable outputs in performance measurement. In addition, suggestions made to the researchers regarding the studies to be carried out within the framework of green management considering undesirable outputs.

Stratejik Yönetim Perspektifinden Türk Demiryolları Performansının Demiryolu Kazaları Dikkate Alınarak İncelenmesi

Abstract

Kıyaslama (benchmarking) stratejik yönetimde sıklıkla kullanılmasına rağmen, Türkiye Cumhuriyeti Devlet Demiryolları (TCDD) gibi bir ülkedeki tüm demiryolu operasyonlarını yürüten firmaların kendilerine özgü yapıları nedeniyle rakipleri ile kıyaslanmaları pek mümkün olamayabilir. Böyle durumlarda, firmanın uzun dönem verileri ile çıktıların girdilere oranına dayanan dinamik veri zarflama analizi yöntemi kullanılabilir. Veri zarflama analizinde son yıllardaki ilerlemelerden biri de istenmeyen çıktıların analize dahil edilebilmesidir. En iyi uygulamanın belirlenmesinde, demiryollarında meydana gelen kazalar gibi istenmeyen durumların da performans değerlendirmesine dahil edilmesi gerekmektedir. Literatürde demiryolu kazalarının dikkate alındığı bir performans değerlendirme çalışmasına rastlanılmamıştır. Bu kapsamda, bu çalışmada demiryollarından istenmeyen çıktı olan demiryolu kazaları dikkate alınarak, TCDD’nin 17 yıllık (2005-2021 arası) verileri ile demiryolu performansının incelenmesi amaçlanmıştır. Bu şekilde, demiryolu performans değerlendirmesi literatürüne istenmeyen çıktıların eklenmesi ile katkı sağlanması amaçlanmaktadır. Analizde toplam raylı sistem uzunluğu (km) ve insan kaynağı girdi olarak, toplam yolcu sayısı ve toplam taşınan yük miktarı istenen çıktı olarak, demiryolu kazası sayısı ise istenmeyen çıktı olarak alınmıştır. Elde edilen bulgular, TCDD için en iyi uygulama örneğinin 2013 yılı olduğunu göstermektedir. Elde edilen bulgulardan uygulayıcılara ve karar vericilere, performans ölçümünde istenmeyen çıktıların göz önünde bulundurulması önerisinde bulunulmuştur. Ayrıca, araştırmacılara yeşil yönetim çerçevesinde gerçekleştirilecek çalışmalarda istenmeyen çıktıların performans ölçümünde dikkate alınmasına ilişkin önerilerde bulunulmuştur.
