Research On EMU Spare Parts Inventory Management Based On Multi-factor Comprehensive Classification

China is currently in the last year of the twelfth five-year railway development plan. The construction of four vertical and four horizontal passenger railway line is steadily developing to achieve a rapid and comfortable passenger transport based on long-term railway network plan, while the existing lines release capacity to meet the great demand for freight transport. On-line operation of domestic EMU means an important milestone in the development of China’s high-speed railway in2007. Meanwhile, China’s high-speed railway equipment manufacturing enterprises promote technology and innovation, overcome various technical difficulties to develop and product domestic EMU successfully. At the same time, operation of domestic EMU brings the rigorous ordeal to spare parts inventory management. Taking the complex types, large numbers and lack of historical consumption data into account, it’s really significant to ensure the scientific and effective inventory management of spare parts.First, analyzing the particularities and needs of EMU spare parts. Manufacturing enterprises establish the unified standard system to make basic components become standardized. Make statistical analysis of CRH2spare parts historical consumption of Beijing EMU overhaul department. Using ARIMA and GM(1,1) model to achieve demand forecasting for different types of spare parts.Furthermore, to improve the current EMU spare parts classification according to the historical components consumption statistics and demand projections. Perform the traditional ABC classification and four-quadrant classification to achieve results evaluations. The implementation of multi-factor comprehensive classification of Beijing EMU overhaul department will lay the foundation for the development of classified inventory management strategies.Finally, verify the distribution of components consumption. Identify suitable inventory management strategies combined with multi-factor classification results. To promote the strategies in specific components and make evaluation of economic situation and inventory service level. The paper’s conclusion will put forward inventory management suggestion and countermeasure for Beijing EMU overhaul.In summary, the paper aims to provide scientific and rational support for current situation under the premise of the existing railway material management system.
