Analysis And Research On Data Driven Fuel Consumption And Maintenance Decision Of Railway Locomotive

With the in-depth application of information technology and the profound changes in the current railway internal and external environment,in order to comprehensively promote enterprise management innovation,in order to convert a large number of historical data into intuitive information for decision-makers,give full play to the role of railway locomotive data statistics,realize the sustainable development of enterprises,improve quality,increase efficiency,reduce cost,better fulfill social responsibility,and give full play to the role of railway locomotive data statistics Based on this,the research work is carried out.Based on the existing ETL,OLAP and other data warehouse technology theories,this research mainly adopts the research methods of integrating theory with practice,combining qualitative and quantitative methods to construct the basic railway locomotive data warehouse,including the theme design,dimension design,dimension table design,fact table design and logic model design of railway locomotive data warehouse,and takes Linhuan branch of Railway Transportation Department of Huaibei Mining Group as an example Based on the case study,from the two aspects of statistical analysis of locomotive fuel consumption and locomotive operation and maintenance,the data analysis methods suitable for the actual application needs of railway departments are selected,including the analysis of influencing factors of locomotive fuel consumption based on ISM model,the analysis of distribution law of braking system and the analysis of main fault factors of braking system.Finally,the decision-making tools and methods of locomotive fuel consumption and maintenance effect analysis are given.Based on the data warehouse technology and other emerging computer tools,this paper explores the team mode of the combination of people and vehicles in the grassroots railway,and the dynamic maintenance system and maintenance quality evaluation system of the grass-roots railway locomotive maintenance based on fault analysis.It combines theory with practice,and is closely linked with the actual situation of the enterprise,which is operable.
