An efficiency analysis of Turkish railways using data envelopment analysis: comparison study

Abstract

The aim of this study is to examine whether Turkey as a candidate for the EU membership, utilises its railway performance. To investigate the Turkish railway's efficiency and identify its current situation, the efficiency of Turkish and EU railway are evaluated by applying data envelopment analysis (DEA) output-oriented model of CRS (CCR) and VRS (BCC) analysis. In this research, each country is considered as a decision-making unit called DMU; every efficiency country is calculated and compared to the other country. In conducted analysis, there are five inputs taken into consideration, along with two outputs distinguished by two forms of transport: passengers and freight transport. The evidence from this study seems to suggest that the technical efficiency of Turkish railway equals 0.89, and sale efficiency equals 0.98, indicating obtained suitability in inputs and outputs for reaching the efficiency boundary.
