Abstract

This study examines the relationship between the operational turnaround time and the rolling stock requirements. In this study, the operational turnaround time of rolling stock is divided into physical turnback time and waiting time. This paper presents a variety of models and estimation results of the existing studies on operational turnaround time. The proposed estimation model of the operational turnaround time in this study is designed to minimize the operational turnaround time in terminus stations, while the rolling stock requirement is reduced. The developed estimation model was applied in a real-world example, and it was found that the operational turnaround time and the required rolling stocks were lessened compared with the current condition. The method presented in this paper is expected to be utilized in train operational planning and rolling stock routing plans, thereby minimizing the rolling stock requirements of existing railway operating authorities.

본 논문은 철도차량의 운영상 반복시간과 차량소요량 사이의 관계를 고찰한다. 철도차량의 운영상 반복시간은 물리적 회차시간과 대기시간으로 구별되며, 본 논문은 이 가운데 운영상 반복시간의 산정모형과 산정 결과에 대한 다양한 고찰을 제시한다. 제시된 운영상 반복시간의 산정모형을 활용하면 터미날 정거장에서의 운영상 반복시간을 최소화 할 수 있도록 설정할 수 있다. 또한 차량소요량이 감소되는 운영상 반복시간 설정조건을 제시한다. 현실적인 데이터를 활용하여 운영상 반복시간 설정조건에 따라 차량소요량이 감소하는 사례와 분석결과를 제시한다. 본 논문에서 제시하는 방법은 기존 철도운영기관의 차량소요량을 최소화 하는 열차운영계획 및 차량운용계획 수립에 활용이 가능할 것으로 기대된다.
