Evaluation of Railway Infrastructure Managers’ Efficiency Using a Pearson’s Correlation-Based DEA Method Model

Efficient management of railway infrastructure is recognized as a cornerstone for the sustainable development of the transport sector, as it plays a critical role in reducing congestion, mitigating environmental pollution, and enhancing mobility.The modernization and optimization of railway systems are essential for the optimal utilization of resources and the advancement of a more competitive and environmentally sustainable sector.Railway infrastructure managers (RIMs) are entrusted with the responsibility of ensuring efficient infrastructure management, maintenance, and modernization, thereby guaranteeing the safety, reliability, and sustainability of railway systems.In this study, a methodological framework was proposed for evaluating the efficiency of RIMs by integrating Pearson's correlation and the Data Envelopment Analysis (DEA) method.The efficiency evaluation was conducted based on key performance indicators (KPIs) associated with railway infrastructure management.Pearson's correlation was employed to analyze the relationships among 35 KPIs, while the DEA method was utilized to identify efficient managers.The developed framework offers a novel approach for creating analytical tools tailored to RIMs, providing regulatory bodies and decision-makers with a valuable toolset to implement best practices and enhance competitiveness.The findings of this study have practical implications, enabling performance comparisons, the development of management strategies, and the formulation of policies aimed at fostering a more sustainable and efficient railway industry.
