Abstract

Existing railway bridges have been going through various improvements since the past, with new improvement plans being formed based on social and technological demands. However, there is the need, above all, for an efficient execution plan due to the great number of sites and excessive amount of required expenses contrary to limited assets. The system itself must be held in question in order to systemize various improvement plans, to define and describe factors while utilizing evaluation methods for significance and correlation to achieve generalization. This paper is focused on determining the priority of various improvement plans through the optimization selection process of mutually evaluating alternative plans under various evaluation standards, thus corresponding to the decision-making purpose. The AHP analysis technique was applied for systemization setting and preference evaluation, while the HPT procedure was applied to develop and select appropriate improvement plan factors.

기존 철도교량은 과거로부터 각종 개량이 시행되고 있고 사회적·기술적인 요구 등으로 새로운 개량계획이 수립되고 있지만 해당 개소가 많고 소요비용이 막대하여 한정된 예산에서는 무엇보다도 효율적인 시행계획이 필요하다. 각종 개량계획을 체계화시키기 위해서는 시스템 차원의 문제로 간주하여 요소들을 정의하고 기술해야 하며 중요도, 상관관계 등은 평가기법을 이용하여 종합화가 이루어져야 한다. 이에 본 연구는 의사결정의 목적에 부합하도록 다양한 평가기준 하에서 대안들을 상호 평가하는 최적화 선정과정을 거쳐 각종 개량계획의 우선순위를 결정하고자 하였다. 체계화 설정과정과 선호도 평가를 위해 AHP 분석기법이 적용되었고 보다 적정한 개량계획의 요소를 도출 선정하고자 수행공학의 절차과정이 활용되었다.
