Nowadays, in all kinds of different manufacturing business, from mechanical processing to electronic manufacturing to product packaging, the applications of assembly lines has become more and more common and important. Due to the complexity of the production and logistics system, lines are often affected by various factors and stop. The stop of lines will not only cause productivity losses, but also can cause the backlog of WIP and impediment of logistics operations. Therefore, the research of how to compress the time of line stop has vital significance.The main research and achievements were as follows:1.This article determined five main reasons that caused the stop of assembly lines of a company by classifying and neatening the line stop data of the first three quarters in2010. The five main reasons are machine down, material shortage, quality problem, process problem and warehouse problem. Then the author used the methods like Reliability Centered Maintenance, Optimize Supply Logistics, Total Quality Management, Operations Standardization and Improve Materials Sending System Of Warehouse to compress the time of line stop. As a result, the time of line stop has decreased by30%.2.Based on the analysis, combined with the actual situation, for a specific reason, to develop appropriate line stop time compression schemes. Then, according to the different priorities for improvement, to develop comprehensive programs to stop time compression line, and line stop after implementation to compare the data to determine the effectiveness of the program.3. Respectively, using the "reliability-centered" service, optimize supply logistics, total quality management, standardization and improvement of operating systems and other warehouse sends the material line stop time compression method to compress the line stop time, so stopping line to reduce the average time30%.
