Abstract: Switches and Crossings (S&C) are a fundamental part of any railway network, they allow trains to switch between tracks and to cross over other tracks. They consist of various electrical and mechanical components to which there is a substantial maintenance cost. Failure of an S&C unit can cause significant disruption to traffic and have large financial implications. Therefore, planning their maintenance is of critical importance to railway asset managers. This research proposes an asset management framework, which models the degradation, failure, inspection and maintenance for the S&C unit. The framework comprises nine Petri net sub-models for the S&C component availability and predicts the number of maintenance interventions in a given time period. This can be used to inform maintenance decision making, with the aim of reducing the life cycle cost of the S&C.

摘要:道岔是铁路网的重要一环,保证了车辆在铁轨中转换线路,跨步到其他轨道。道岔由各种电气、机械组件构成,而且维护成本很高。一个道岔组件出现故障,会严重破坏交通,带来巨大的财务损失。因此,维护道岔对于铁路资产管理公司至关重要。本研究提出一个资产管理框架,用于解决道岔组件退化、故障的问题,并且进行检查和维护。该框架包括九个适用于道岔路口组件的佩特里网子模型,预计在特定时间内统计维修注入总数。在维修期间,提供维修决策,以降低道岔的使用期内的维修成本。
