【摘要】 近年,我国工业有了迅猛发展,如今已然体系完备,品类齐全。但随着经济全球化的进程,国内劳动力成本的上涨以及核心技术欠佳,我国工业也正面临着巨大压力。作为传统制造业,PM公司是最早来大陆投资建厂的港资企业,PM公司成功搭乘了中国工业飞速发展的黄金班列,然而,在长期的发展过程中也积淀了很多亟待解决的问题。精益生产是当前世界公认的优秀生产管理体系。在国外已有20多年的发展和实践经验。近年来我国企业也纷纷引入了精益生产。PM公司在解决发展中遇到的问题时,以降本增效为核心出发点,聘请咨询公司推行精益生产,建立精益小组,仅半年多的时间就成绩斐然。本文以PM公司激光器车间为研究对象,利用绘制价值流程图找出该车间存在的主要问题是生产线不平衡,设备综合效率低,库存水平高及合格率低。再根据精益相关理论和分析工具指出这些问的原因分别是车间布局不合理,设备故障率高,生产组织模式落后和现场管理不到位。最后逐一对其进行优化:运用车间布局理论优化车间布局,减少物流搬运路线和时间;通过制订设备故障预防维护制度和专人维修制减少设备故障率;引入PFMEA从人、机、料、法、环各方面提升现场管理水平;新研夹具、人-机效率分析、工时测定标准化等措施极大地提升了生产线平衡率。效率增长,企业竞争力也大幅增长。另外还在车间推行5S管理,全员生产保全持续改善,建立绩效考核制,以保障改善效果延续。更多还原

【Abstract】 Since the founding of the People’s Republic of China,China’s industry has developed rapidly,and now it has a complete system and a complete range of products.However,with the process of economic globalization,the increase in domestic labor costs and the poor core technology,China’s industry is also facing tremendous pressure.As a traditional manufacturing industry,PM Company is the earliest Hong Kong-funded enterprise to invest and build factories in the mainland.PM Company successfully took the golden train of the rapid development of China’s industry.However,many problems that need to be solved have also accumulated in the long-term development process.Lean production is currently recognized as an excellent production management system in the world.It has more than 20 years of development and practical experience abroad.In recent years,Chinese enterprises have also introduced lean production one after another.When PM Company solves the problems encountered in its development,it hires a consulting company to implement lean production,establishes a lean team,and has achieved remarkable results in just over half a year.This article takes the laser workshop of PM Company as the research object,uses the value flow chart to find out the main problems of the workshop: unbalanced production lines,low equipment comprehensive efficiency,high inventory levels,and low pass rate.Then,according to the lean-related theories and analysis tools,it points out that the reasons for these problems are the unreasonable workshop layout,high equipment failure rate,backward production organization mode,and poor on-site management.Finally,it is optimized one by one:the workshop layout theory is used to optimize the workshop layout,reducing the logistics handling routes and time;by formulating the equipment failure prevention and maintenance system and the dedicated maintenance system,the equipment failure rate is reduced;the introduction of PFMEA improves the on-site management level from the aspects of people,machines,materials,methods,and the environment;new research jigs,man-machine efficiency analysis,and standardization of working hours measurement have greatly improved the line balance.The increase in efficiency has also greatly increased the competitiveness of enterprises.In addition,5S management is also implemented in the workshop,total productive maintenance for all employees continues to be improved,and a performance appraisal system is established to ensure the continuation of the improvement effect.更多还原
