【摘要】：进入2000年以来,随着中国加入WTO和国内经济增速高位运行,汽车需求一直不断在扩大,中国成为世界最大市场之一。乘用车价格的大幅下降和人均收入提高的综合作用,导致需求和销量快速增长。自2009年以来我国汽车销量已经持续稳居世界第一,经过连续几年千万台整车的市场供应调整,目前我国汽车产业已经由高速增长进入小幅增长阶段,所以为了抢占更多的市场份额,所有汽车厂都面临着控制成本和提高质量的双重考验。当前中国汽车制造企业正努力通过成本控制、加强质量管理和缩短开发和投产周期等更多手段提升企业竞争力。对于很多制造企业来说,虽然已经应用了ERP、CRM、PLM等企业级管理软件,但生产制造过程仍然犹如"黑箱",生产现场的管控能力十分薄弱。许多汽车厂的生产车间虽然实现了自动化和规范化管理,但是还缺乏信息系统的支撑,导致ERP应用过程中,生产计划下达之后的执行情况不能及时反馈,使ERP难以实现对企业的事实管控,也难以实现对生产过程的追溯。同时,由于缺乏信息化应用系统,车间的工人、设备、物料等资源还不能被合理调度,导致车间的生产效率不高,生产质量也得不到根本保障。在这种背景下,制造执行系统(Manufacturing Execution System,MES)逐渐成为广大制造企业关注的热点。本文通过对华晨中华汽车公司的质量管理方式和生产现状进行分析,设计出整个质量管理系统。首先,从问题管理方面,整个管理思路遵循PDCA原则。通过对缺陷名称的标准化,系统能够对生产过程中产生的产品缺陷进行统计、上报、问题跟踪、解决措施跟踪等全面管理,使产品质量全面提升。其次,对关键零件进行追溯,跟踪出厂后的质量状态,达到国家对召回的要求。最后,在绩效管理方面,设定工厂级质量目标,并且对车间级、班段级实行目标层层分解。通过对每一层的目标管理,降低质量成本和生产成本,实现精益生产。全文结合MES系统质量模块的工作需求,落实到质量管理系统的每个模块具体要求和界面,对未来MES系统质量的开发和实施具有指导性意义。
[Abstract]:Since 2000, with China's entry into WTO and the high speed of domestic economic growth, automobile demand has been expanding, and China has become one of the largest markets in the world. The combined effect of a sharp drop in passenger car prices and an increase in per capita income has led to rapid growth in demand and sales. Since 2009, China's automobile sales have consistently ranked first in the world. After several consecutive years of adjustment of the market supply of 10 million vehicles, the auto industry in our country has now moved from a high speed growth to a small growth stage. So in order to grab more market share, all automobile factories are faced with the double test of controlling cost and improving quality. At present, China's automobile manufacturing enterprises are trying to improve their competitiveness by means of cost control, strengthening quality management and shortening the development and production cycle. For many manufacturing enterprises, although ERP,CRM,PLM and other enterprise-level management software have been used, the manufacturing process is still like a "black box", and the control ability of the production site is very weak. Although many auto factories have realized automation and standardized management, they still lack the support of information system, which leads to the failure of timely feedback on the implementation after the production plan is issued in the ERP application process. It is difficult for ERP to control the facts of the enterprise and to trace the production process. At the same time, due to the lack of information application system, workshop workers, equipment, materials and other resources can not be properly scheduled, resulting in the workshop production efficiency is not high, production quality can not be fundamentally guaranteed. Under this background, manufacturing execution system (Manufacturing Execution System,MES) has gradually become the focus of attention of manufacturing enterprises. Based on the analysis of quality management mode and production status of brilliance China Motor Company, the whole quality management system is designed in this paper. First of all, from the aspect of problem management, the whole management thought follows the PDCA principle. Through the standardization of defect names, the system can make statistics, report, problem tracking, solution tracking and other overall management of product defects in the production process, so as to improve the quality of products. Secondly, the key parts are traced back and the quality status of the factory is tracked to meet the national recall requirements. Finally, in the aspect of performance management, the factory level quality target is set, and the workshop level and the shift level are decomposed layer by layer. Lean production can be achieved by reducing quality cost and production cost through objective management of each layer. According to the working requirements of MES system quality module, the paper implements the specific requirements and interfaces of each module of the quality management system, which is of guiding significance for the development and implementation of MES system quality in the future.
