Abstract

Investment in railroad, it is very important to find a way to increase a benefit to make the economic efficiency more positive, but is also considering that the cost will be higher. In this paper, we suggest a optimized model for increasing the benefit of railroad business considering of stopping patterns. According to existing analytical method, the operation hour is calculated based on that scenario regarding that it stops at all major stations but it does not fit the actual operation conditions. Considering various stopping patterns can be reasonably calculated the cost for required rail cars in the planning stages, and can also affect economic efficiency in a positive way.

철도투자사업의 경제성 증대를 위해서는 새로운 편익의 발굴도 중요하지만 비용 부문에서 과다하게 책정되는 부분을 개선하는 것도 매우 중요하다. 본 논문은 철도부문의 편익을 제고하기 위해 철도차량의 정차 패턴까지 고려한 최적화 모형을 이용하여 분석할 것을 제안한다. 기존의 방법은 주요 역에 모두 정차한다는 시나리오를 토대로 운행시간을 작성하였으나 이는 실제 운행 여건과는 맞지 않는다. 열차별 정차 패턴을 고려하여 소요 차량수를 산정할 경우 계획 단계에서 적용되는 차량구입비를 합리적으로 산정할 수 있고 경제성 분석에도 긍정적인 영향을 주는 것으로 분석되었다.
