【摘要】：在当今时代,国际化进程加速,国内外市场竞争越来越激烈,客户的个性化需求越来越高,多品种小批量的生产特点越来越明显,汽车企业也不例外。而多品种中小批量的特点对生产组织的要求越来越高;大多数企业都是处于供应链的中间环节,客户要求不断的降价,而原材料成本持续上扬,加上人员成本的上升,企业成本压力越来越大。同时客户交货周期要求越来越短、质量要求越来越高,很明显降本增效已经是很多企业面对当前困难采取的必要手段。本文结合延锋百利得(上海)汽车安全系统有限公司(YFKSS)的安全气囊生产线所存在的问题,提出了一种精益思想的安全气囊生产方式。本文首先对YFKSS公司的相关信息进行理论研究、收集和整理当前生产数据的基础上,分析了YFKSS公司目前所存在的问题。建立了基于U型线安全气囊生产线的均衡化设计,改进后的U型生产线,最后获得了较高的性能提升,其生产平衡率可以达到96.7%。本文还结合本公司实际需求通过生产线平准化设计和看板管理实现了YFKSS安全气囊的拉动式生产方式,然后通过对YFKSS整个生产系统价值流的分析,绘制YFKSS安全气囊生产的未来价值流图;同时对装配生产线的均衡化、看板管理等问题进行了深入刨析,并进行反复地实践调整,有效地提高了产品生产效率,降低生产成本,建立起了一套比较完整的安全气囊车间看板管理系统实施方案。通过对当前价值流程图的改善获得较高增值时间值的未来价值流图,其加工增值比由仅仅为0.0379%提升为0.1705%,提升了4.5倍。
[Abstract]:In today's era, the internationalization process accelerates, the domestic and foreign market competition is more and more intense, the customer's individuation demand is higher and higher, the multi-variety small batch production characteristic is more and more obvious, the automobile enterprise is no exception. However, the characteristics of multi-variety, medium and small batch are more and more demanding to the production organization. Most enterprises are in the middle of the supply chain, the customer requests the price of price continuously, and the raw material cost continues to rise, together with the increase of the personnel cost, the pressure of the enterprise cost is increasing. At the same time, the requirement of customer delivery period is getting shorter and shorter, and the quality requirement is higher and higher. It is obvious that reducing the cost and increasing efficiency is the necessary means for many enterprises to face the current difficulties. Based on the existing problems in (YFKSS) airbag production line of Yenfeng Bailide (Shanghai) Automotive Safety system Co., Ltd., a lean production method of airbag is proposed in this paper. In this paper, firstly, the related information of YFKSS Company is studied theoretically, and the current production data are collected and collated, and the existing problems of YFKSS Company are analyzed. Based on the equalization design of U-line airbag production line, the improved U-shaped production line has been established. Finally, a higher performance has been obtained, and the production balance rate can reach 96.7%. This paper also realizes the YFKSS airbag pull production mode through the production line leveling design and Kanban management according to the actual demand of the company, and then through the analysis of the value flow of the whole YFKSS production system, Draw the future value flow chart of YFKSS airbag production; At the same time, the equalization of assembly line, Kanban management and other problems are deeply analyzed, and repeated practical adjustments are carried out, which effectively improve the production efficiency and reduce the production cost. Set up a set of relatively complete airbag workshop Kanban management system implementation scheme. Through the improvement of the current value flow chart, the value flow chart with higher value added time is obtained, and the processing value added ratio is raised from only 0.0379% to 0.1705, which is 4.5 times higher.
