【摘要】：随着新的生产方式的不断革新,新的管理方式的不断创新,企业在生产与管理过程中也要不断及时调整,通过不断调整生产模式来提高生产效率,从而实现企业利益的长远发展。本文结合S企业的生产实践,通过现状分析,针对制造型企业在生产制造过程当中呈现出的诸如产能不匹配、产线不平衡、生产流程和工艺不合理、物流不通顺、现场管理混乱等诸多问题,应用精益生产思想与车间布局改善相结合的理念,从分析车间生产能力和生产现场入手,对数控车间布局和物流规划进行精益设计与改善,使数控车间的空间及设备能力得以更加充分的利用,生产现场更为有序,物流简洁通畅。特别是,面对整个数控车间生产系统状况以及影响产能匹配的瓶颈问题进行深入分析,构建了基于精益生产系统的规划模型,使得瓶颈问题得到较好地解决。经过生产布局改善,设备和人员利用率明显提高,生产柔性和平衡性显著提高。本文基于精益生产的研究思路从传统的物流规划模型与一个流的生产布局入手,对数控车间的生产与调度进行了分析比较;在规划物流系统的同时,通过对数控车间生产现场分析,对生产工艺进行了改善,并利用5S管理、仓储管理等方法对车间生产现场和仓储库存进行了有效地改善。实践证明,实施精益思想是企业贯彻和提升内在竞争力的重要手段,而系统的设计手段和可操作性的现场管理方法可为企业提供具有可实施价值的实施方法。
[Abstract]:With the continuous innovation of the new production mode and the continuous innovation of the new management mode, the enterprise should adjust in time in the process of production and management, and improve the production efficiency by constantly adjusting the production mode. In order to achieve the long-term development of the interests of enterprises. Based on the production practice of S enterprise, through the analysis of the present situation, this paper aims at the problems that the manufacturing enterprises present in the manufacturing process, such as the mismatch of production capacity, the imbalance of production line, the unreasonable production process and process, and the unsmooth logistics. Based on the idea of combining lean production idea with workshop layout improvement, this paper starts with the analysis of workshop production capacity and production site, and carries out lean design and improvement of numerical control workshop layout and logistics planning. To make full use of the space and equipment of the NC workshop, the production site is more orderly, the logistics is simple and unobstructed. Especially, in the face of the whole NC workshop production system condition and the bottleneck problem which affects the productivity matching, the planning model based on lean production system is constructed, which makes the bottleneck problem solved better. Through the improvement of production layout, the utilization ratio of equipment and personnel is improved obviously, and the flexibility and balance of production are improved significantly. Based on lean production, this paper analyzes and compares the production and scheduling of numerical control workshop from the traditional logistics planning model and the production layout of a flow. At the same time of planning logistics system, the production process is improved by analyzing the production site of NC workshop, and the production site and warehouse inventory are effectively improved by means of 5S management and warehousing management. Practice has proved that the implementation of lean thought is an important means for enterprises to carry out and enhance their internal competitiveness, and systematic design means and operable on-site management methods can provide enterprises with implementable value of implementation methods.
