【摘要】：随着市场经济的不断发展和完善,企业间的竞争将愈演愈烈。提高自身的核心竞争力和适应瞬息万变的市场,从而快速占领市场是现代企业一直孜孜以求的目标。KB公司虽为行业的领跑者,但在面临竞争者迎头赶上、客户越来越短的交货周期和不断的降价要求的情况下,KB同样也如其他制造型企业一样,感到“危机四伏”。所以,改善内部生产流程、推行精益生产对于KB公司的内部管理来说,已经迫不及待。本文所选的研究主题是KB公司生产流程的优化研究,研究的价值对象是CCBII产品。研究目的是帮助企业寻求生产运营过程改善的突破点,降本增效,以助于企业在日趋激烈在竞争中提高自身在市场中的竞争力。本文应用价值流图析工具,在确定价值对象后,以其实际生产流程为纲要,通过车间实地观察,询问,进行数据记录,绘制了当前价值流程图,在研究价值流动过程中发现增值部分和非增值部分,寻找到改善点,绘制了未来价值流图,制定价值流改善计划,提出布局优化、物流优化、设备优化、快速换模(SMED)、看板管理等,讨论改善方案,进行实地模拟最终建立基于精益思想的标准化作业流程,交货周期由38.3天缩短成18天。同时,此优化项目提高了生产线平衡率,单件产品人员走动距离减少近50%,减少作业人数,质量一次性不合格率由5.04%降低到1%左右,节约场地面积,提高生产效率,降低了在制品库存等。本文阐述了一个以精益思想为核心的生产流程优化的研究、分析、实施的过程,具有常规改善所具备的特点和普遍性,它符合现代企业走向精益管理的发展需求,是企业取得长足发展的坚固基石。同时,本文也结合了案例企业自身的一些特点,活学活用,进行适当的变通,最终取得了实质性的改善效果。希望本文能给需要寻求和探究生产流程优化的企业带来一些帮助和具有一些指导意义。
[Abstract]:With the continuous development and improvement of the market economy, the competition among enterprises will become more and more intense, improve their core competitiveness and adapt to the ever-changing market. Thus the rapid occupation of the market is the goal of modern enterprises. KB company is the industry leader, but in the face of competitors to catch up. Customers with shorter delivery cycles and constant price reduction requirements are also feeling the same "crisis" as other manufacturing enterprises. Therefore, improve the internal production process. To promote lean production for the internal management of KB, can not wait. This paper selected the research theme is the optimization of the production process of KB company. The value object of the study is CCBII products. The purpose of the study is to help enterprises to find a breakthrough point to improve the process of production and operation, reducing costs and increasing efficiency. In order to help enterprises in the increasingly fierce competition to improve their competitiveness in the market. This paper applies the value flow chart analysis tool, after determining the value object, taking its actual production process as the outline, through the workshop field observation. Inquiring, recording data, drawing current flow chart of value, finding value-added part and non-value-added part in the process of studying value flow, finding improvement point and drawing future value flow chart. Make value flow improvement plan, put forward layout optimization, logistics optimization, equipment optimization, rapid mold change, Kanban management, etc., discuss the improvement plan. The field simulation results in the establishment of standardized operation flow based on lean thinking, and the delivery period is shortened from 38.3 days to 18 days. At the same time, this optimization project improves the balance rate of production line. The walking distance of individual product personnel is reduced by nearly 50 percent, the number of people working is reduced, the one-off nonconformity rate of quality is reduced from 5.04% to about 1%, the area of the site is saved and the production efficiency is improved. This paper describes a lean thought as the core of the production process optimization research, analysis, implementation of the process, with the characteristics of conventional improvement and universality. It conforms to the development needs of modern enterprises towards lean management, and is the solid foundation stone for enterprises to make great progress. At the same time, this paper also combines some characteristics of case enterprises, learn to use them alive, and make appropriate modifications. We hope this paper can bring some help and guidance to the enterprises that need to seek and explore the optimization of production process.
