Application of DMAIC Tools for Locomotive Maintenance Optimization

Abstract:

The quality improving of locomotive maintenance service is studied based on Six Sigma. The maintenance service progress has been optimized by DMAIC mode. First of all, the quality problems have been proposed. Then, the factors which impact on quality of after-sales service are found by QC tools. Secondly, the main problems in the progress would be controlled conveniently. Finally, the improved maintenance services process is developed correspondingly. In order to ensure the quality of the maintenance in the delivery period, some measures are taken such as adjusting the allocation time in the repair process, developing a strict examination system. The result shows that the maintenance efficiency and customer satisfaction has been improved significantly.
