Based On The Network Planning Technique Of The EMU Maintenance Process Optimization Research

To ensure high reliability and good technical condition. After run a certain mileage or time, EMU must return to the Emu base for maintenance.EMU maintenance work is a complex project, which requires multi-sectoral cooperation, will consume a lot of resources and costs. Once an EMU break down will reduce the running time online, EMU transportation business will suffer. EMU authorities require repair work time as short as possible as high quality maintenance and repair costs as low as possible.Therefore, the rational organization of maintenance work carried out to determine the excellent repair process, minimizing maintenance requirements EMU caused libraries to stop time, to existing operations EMU maintenance workflow analysis and optimization.This paper analyzes and summarizes the EMU major maintenance ideas, maintenance mode and repair techniques, introduction of absorbing foreign EMU advanced technology after the self-developed CRH6type intercity EMU technical characteristics, analyze its relationship with CRH2type EMU and summarizes the differences.In this paper, reference Wuhan, Xi’an EMU base CRH2type EMU maintenance experience, made applicable to CRH6type intercity EMU in three hundred thousand kilometers pilot phase maintenance programs, define the maintenance level, repair cycle, maintenance scope and maintenance content.This paper will introduce the engineering management idea into EMU maintenance work, and introduce the development history of network planning technology,which is widely used in construction, engineering and other fields of software development project management.we introduce the development process of network planning techniques to analyze the principles and basic processes.Point out the meaning and significance of analyzing EMU maintenance management by using network planning technique. The use of network planning technology and software analysis using software CC Project based CRH2type EMU maintenance experience developed CRH6type EMU maintenance workflow problems, identify existing production process production potential. The use of network planning technology CRH6type EMU twelve maintenance workflow analysis, combing the workplace logical relationships and importance of the maintenance work on the twelve duration, resources, cost optimization analysis. Right CRH6type EMU bogie repair process optimization analysis. Capacity constraints for the maintenance solutions for network planning optimization process bogie maintenance.After optimization of network planning techniques to identify the factors limiting production efficiency maintenance and propose appropriate solutions, compressed work schedule maintenance, improve maintenance efficiency. Also proposed network planning methods for maintenance work on cost control and resource consumption control.Maintenance work by the use of network planning techniques, this paper proves network planning technology in EMU maintenance work management has very broad application prospects. Network planning technology managers to develop scientific research can be used as a reasonable and efficient maintenance production planning, organization and implementation of scientific maintenance work, analyze and identify existing bottlenecks in the production process maintenance very important adjunct to the protection of railway transportation safety, improve the maintenance efficiency of the railway to the railway users to provide quality services has an important significance.
