毕业论文关键词：流程程序分析；风机装配线；ECRS 四大原则 The Application of Flow Process Analysis In An Enterprise
ABSTRACT With the rapid development of global economic market integration,the commercial competition is growing more and more violent.The market demand has been developd to pluralism inpidualized era from the sellers market into the buyers market.The samll batch production has become the leading direction.In this situation,the concepts of lean production and industrial engineering have been more and more recognized and widely uesed.To strengthen the competition advantage,the concept of IE and Lean production have been introduced to our country by some enterprise.But there is still no so many successful implementation so far. In this paper,the fan assembly line of envision is regarded as the study object.Based on the field investigation lasted one moth,I drawed the process flow diagram of the gearbox assemblyline.With the help of the process flow analysis theory and questioning skills,I tried analyzing problems and come up with some improving methods using the ECRS principle in order to reduce the cycle time and improve efficiency effectively.
KEY WORDS: Process flow analysis；The fan assembly line；ECRS four principles

流程程序分析在某企业的应用 1 绪论 1.1 论文选题背景 进入 21世纪，随着全球经济一体化的发展，市场竞争环境日趋激烈，能够快速响应、满足客户对产品的多元化需求也逐渐成为企业最重要的竞争力。对于诸多制造型企业来讲，产品质量稳定性难以保障、库存占用资金量大、交货期延长、生产系统效率不高、有订单却做不出来等不良现象，已经成为阻碍其生存和发展的致命因素。对此，很多中国制造企业决定从从精益化管理的角度出发，通过引进精益生产与工业工程相关的理论方法，进行流程再造，合理布局生产系统运行过程，加强对生产管理的过程控制，通过提高生产制造系统的市场灵活性、提升企业对市场的反应速度，最终提高企业的竞争力和盈利水平。然而，由于存在对精益生产理念认识不足、高层参与不足、缺乏整体配合，急功近利、急于求成，热衷于学习精益技术和工具，对精益的文化和理念导入不足等原因，国内导入精益生产的成功案例并不多。 近年来，随着全球气候变化威胁加剧，风力发电作为新能源的代表越来越受到国家的重视与推广。面对国内外诸多风机厂商的激烈竞争，远景能源率先打破低速风机的技术壁垒，于2009 年推出全球首款低风速智能风机，并凭借年均60%以上的增长速度迅速成长为中国第三大风机供应商，最大的海上风机供应商。然而，公司的高速发展越来越受到产能的制约，如何提高装配线的作业效率，降低人工成本和材料损耗，降低生产节拍，保质保量，并且能够按工期交货，成为公司面临的重要课题。
