Research on Maintenance Cost Optimization of Electric Locomotive Based on Life Cycle Cost Analysis
Through the life cycle cost catalog analysis for electric locomotive,a simple cost model is established from the user's perspective then obtained related cost composition.Maintenance cost is an important part of the life cycle cost of electric locomotives,which has a large optimization space.By calculating the maintenance cost of electric locomotive,the main factors affecting the maintenance cost are obtained,and the optimization measures are analyzed.Through sensitivity analysis,the main systems and components that affect the maintenance cost are obtained,and the key objects of maintenance cost optimization are identified.Based on the analysis of maintenance cost factors and the research of key objects,the maintenance cost optimization strategy is proposed.
