摘要
基于全生命周期成本和可靠性理论,文章提出一种地铁列车全生命周期维修经济性分析模型.以地铁列车全生命周期维修总成本模型为基础,基于可靠性理论,应用修复维修、预防维修的维修次数计算模型和换件、不换件条件下的修复维修、预防维修的平均维修时间计算模型,将人工、物料等成本数据代入模型中,可计算得到地铁列车全生命周期维修总成本.以建立的某城市地铁全生命周期维修成本模型为例,分析预防维修、修复维修的成本占比与人工、物料成本占比,通过单因素敏感度分析,识别出全生命周期成本的关键影响因素,从而为集中利用有限资源,降低地铁列车全生命周期成本提供指导.
Abstract
Based on the full-lifecycle cost and reliability theory,this article proposes an economic analysis model for the maintenance of metro trains throughout their full-lifecycle.Based on the total maintenance cost model of the full-lifecycle of metro trains,and based on reliability theory,by inputting cost data such as labor and materials into the model,the total maintenance cost of the full-lifecycle of metro trains can be calculated on the calculation model of repair and preventive maintenance counts and the average maintenance period calculation model of repair and preventive maintenance under replacement and non-replacement conditions.Taking the established maintenance cost model for the full-lifecycle of a metro system as an example,this paper analyzes the cost proportion of preventive maintenance and repair maintenance,as well as the proportion of labor and material costs.Through single factor sensitivity analysis,the key influencing factors of the full-lifecycle cost are identified,providing guidance for the intensive limited resources utilization and the full-lifecycle cost reduction of metro trains.
