철도궤도 자산관리를 위한 LCC적용 현황 및 개발 방향

초록

The railroad track as a part of the railroad asset need enormous expenses at construction and maintenance like other civil infrastructures. To do this economically, life cycle cost(LCC) analysis for its whole life process is required. In domestic railroad industry, LCC analysis method applied at planning and design stage as a tool of VE or used as a tool of alternative comparison for track structure. But never been applied for maintenance. For application of LCC on track maintenance, there could be solved the problems originated from railroad system characteristics. Separation of asset management and train operation, train run on dedicated line, track deterioration can be easily measured by track recording system and its progress can be estimated by standard deviation. In the 1990s European EU directive 91/440 requires that aseparate organization has to provide the railway infrastructure in order to create profit-driven transport operators and transparent cost accounting of infrastructure maintenance and operation. Decisions in design and maintenance have to based on estimates of availability, reliability and maintenance costs in order to minimize the total costs of ownership for the infrastructure owner. Life cycle cost analysis was applied for finding answers. This report reviewed european cases and presented the direction for application of LCC on railroad asset management.
