摘要
城市轨道交通车辆作为城市轨道交通中最为关键也最为昂贵的设备,其采购金额占到工程总造价的10%~15%;但是城市轨道交通车辆全寿命周期长达30年,其后期的运行及维修养护成本更为高昂。在传统招标模式下,采购比较注重评价车辆初始采购成本,往往忽视后期更为庞大的能耗成本及车辆维护成本。针对性地引入车辆全寿命周期成本招标模式,尝试解决建设与运营分割的弊端,统筹考虑车辆全寿命周期中所产生的费用,实现采购单位整体效益的最优化。
Vehicle is the most critical and expensive equipment in urban rail transit,its purchase amount accounts for 10 to 15%of the total project cost.Since the life cycle of urban rail transit vehicle is up to 30 years,the operation and maintenance cost may be even more costly.In traditional bidding mode,the initial purchase cost of vehicle attracts more attention in evaluation,while the huge energy consumption and maintenance costs tend to be ignored.By introducing the bidding mode of urban rail transit vehicle life cycle cost,the goal to achieve the overall benefit optimization for purchasing department is proposed,which will solve the disadvantages of the construction and operation division,consider the overall cost incurred in the vehicle life cycle.
