Abstract

An effective approach to distributing budget to railway line facility improvement is to use investment priorities of railway line segments based on their deterioration. In this paper we present an evaluation method of railway line segment deterioration which can be used to distribute limited budget. Railway line facilities include rail track, railroad switch, subgrade, bridge, tunnel. These facilities and line shape can affect line segment deterioration. Deterioration evaluation method we present is a weighted sum of each component deterioration scores. The component weight can be obtained from experts using analytic hierarchy process.

정된 예산으로 철도선로시설을 개선하고자 할 때 사용할 수 있는 효과적인 예산배분 방법 중 하나는 가장 노후도가 심각한 선로구간부터 우선적으로 예산을 투입하는 것이다. 본 논문에서는 예산배분에 사용할 수 있는 선로구간 노후도 평가방법을 제시한다. 선로구간의 노후도는 궤도, 분기기, 노반, 교량, 터널 등 요소 시설물의 노후도로 결정되며 궤도의 선형 또한 선로구간 노후도에 영향을 준다. 본 논문에서 제시하는 노후도 평가 방법은 각 요소의 노후도 점수에 AHP로 구한 요소 가중치를 반영하여 선로구간 노후도 점수를 구하는 것이다.
