| In modern manufacturing companies, it’s very hard to achieve line balancing completely due to the variations of processing time in each process of the line. If we want to improve productivity, we must find the bottlenecks in the production line. For the bottleneck processes, we need to optimize time and/or procedure, adjust the production line work load of each process, so that the processing time for every work station is almost equal. Thus we can eliminate wastes; maximize the production efficiency. That is the production line balancing problem.This thesis takes the existing production lines of ECU department from the VED Division of Continental Automotive systems as the object of the study. It focuses on the balance of the production line and aims to provide theoretical guidance and practical experience to solve the line balancing problems.The thesis is divided into seven chapters. The first chapter introduces the background of the research, and reviews to the extensive literature on the analysis of production line balancing research, points out its advantages and disadvantages of different line-balancing methods. The second chapter reviews the relative concept of production line balancing problem in the field of industrial engineering fieldshttp://cn.bing.com/dict/clientsearch?mkt=zh-CN&setLang=zh&form=BDVEHC&ClientVer=BDDTV3.2.0.4311&q=%E5%B7%A5%E4%B8%9A%E5%B7%A5%E7%A8%8B%E9%A2%86%E5%9F%9F and lay the theoretical foundation for the third chapter. Then in the third chapter, the thesis gives brief introduction on the current production line, and implements associated measurements to provide data source for subsequent analysis. Chapter IV takes two processes as examples from ESC Backend, the ECSR, 5W1 H methods are applied in human-machine operation analysis, both hands operation analysis and motion analysis. Furthermore improvements executed based on them. Chapter V uses SIMUL8 simulation software for the balance of the previous simulation analysis, and presents evaluation of the improvement. In Chapter VI, Visual Management is used in the production line based on the results of the above analysis, and then a brief introduction on Andon System is illustrated.Finally, the thesis summarizes the work and conclusions, and points out the limitations of the research and the prospects in future work... |
