Abstract : Life cycle cost analysis is compulsively required for the system operation. System operation costs are consisted of acqui-sition, operation, maintenance and so on. In the beginning of the system planning, we need to take into account of vari-ous costs following the system operating. To implement LCC, we need to analyze system life cycle to identify all costsduring system life. The costs can be divided into three parts. The first part is purchasing cost, the second for operatingcost and the last for disposal cost. The second operating cost can be decomposed of operating cost included labor, energyconsumption cost for system running, maintenance costs to keep systems healthy, delay cost caused from maintenanceand hazard cost, and so on. In this paper, we carried out for railway locomotives which operate over more 30years andwhich cost about 10 million USD. We decompose the life cycle of the locomotives and break down the locomotives intosubsystems to require maintenance or not, and subsystems to need energy or not. We showed how to decide optimallocomotives through cost identification and system breakdown.
