【摘要】 随着国内各行业体系的快速发展,企业间的竞争日益激烈化,其利润增长空间也在逐渐缩减。当下,汽车制造行业也在降低成本与提升效率方面遇到瓶颈。基于现有资源限制和劳动力成本增加等诸多压力,不断有企业将注意力关注到物流上来。但从实际生产经验中可以看出,国内多数中等企业,其生产物流还存在着功能、结构较为单一的情况,并缺乏整体性、系统性。因此,怎样在现有条件下,利用物流改善实现增效降本生产是N公司总装车间需要解决的问题。本文基于发现问题、分析问题和解决问题的思路,主要研究了 N公司总装车间在物料搬运、包装过度和现场物料堆积等方面发现的问题,并以其为主导,通过布局优化提升来提高总装车间的物流生产效率。全文主要包括了以下几个部分:(1)简要提出了物流的相关影响因素和生产物流、布局及精益方面的理论知识。通过调研N公司总装车间生产现状、布局现状,发现了车间布局、包装及生产过程中存在的一系列影响效率、影响现场的问题,继而分析提出了车间进行布局设施调整的急迫性,并针对分析结果确定了本次进行布局调整的目标。(2)分析车间原有布局。通过布局改善方法,具体选用了 SLP(Systematic Layout Planning)系统布置设计方法,通过划分车间内作业单位和需求面积,研究完成整个车间的相互关系分析,并通过线型图搭建来完成整个车间的布局方案设计规划。(3)利用加权因素比较法评估确定出最优方案,并在此基础上,进一步结合5S(SEIRI SEITON SEISO SETKETSU SHITSUKE)精益生产管理方法,利用包装改善整合和立体存放改善整合两个措施,来完成对车间布局的现场优化提升,使布局更合理。(4)从物流搬运量、车间现场和物料存储、成效四个方面,对改善前后的实际成果进行比较验证,以证实车间实施物流改进的实用性和有效性。随着物流管理需求的不断提升,一些科学的物流改善方法,如运输改善、配送改善、仓储改善等,都将在企业得到推广应用。本文结合N公司总装车间提出的物流改善措施,具有较强的实用价值,为同行业物流改善提升给予了一定的参考支持。更多还原

【Abstract】 With the rapid development of domestic industrial systems,the competition among enterprises is becoming increasingly fierce,and their profit growth space is also gradually shrinking.At present,the automobile manufacturing industry also faces bottlenecks in reducing costs and improving efficiency.Based on the existing resource constraints and increased labor cost and other pressures,more and more enterprises are paying attention to logistics.However,from the actual production experience,we can see that the production logistics of most medium-sized enterprises in China still has a single function,structure,and lacks integrity,systematic situation.Therefore,under the existing conditions,how to use logistics to improve efficiency and reduce cost is a problem that needs to be solved in the assembly workshop of N company.Based on the idea of finding,analyzing and solving problems,this paper mainly studies the problems found in the general assembly workshop of N company in material handling,excessive packaging and on-site material accumulation,and takes them as the leading factor to improve the logistics production efficiency of the general assembly workshop through layout optimization.The paper mainly includes the following parts:(1)It briefly puts forward the relevant influencing factors of logistics and the theoretical knowledge of production logistics,layout and lean.Through investigating the production status and layout status of the general assembly workshop of N company,a series of problems affecting efficiency and site in the workshop layout,packaging and production process were found,and then the urgency of the workshop layout facility adjustment was analyzed and put forward,and the goal of this layout adjustment was determined based on the analysis results.(2)Analyze the original layout of the workshop.Through the layout improvement method,the SLP(Systematic Layout Planning)system layout design method is specifically selected.By dividing the work units and the required area in the workshop,the relationship analysis of the entire workshop is studied and completed,and the layout design and planning of the entire workshop is completed through the establishment of the line diagram.(3)The weighted factor comparison method is used to evaluate and determine the optimal plan,and on this basis,combined with the 5S(SEIRI SEITON SEISO SETKETSU SHITSUKE)lean production management method,the packaging improvement integration and three-dimensional storage improvement integration are used to complete the on-site optimization and upgrading of the workshop layout,so as to make the layout more reasonable.(4)Compare and verify the actual results before and after the improvement from the four aspects of logistics handling volume,workshop site and material storage,and effectiveness,to verify the practicability and effectiveness of the implementation of logistics improvement in the workshop.With the increasing demand for logistics management,some scientific logistics improvement methods,such as transportation improvement,distribution improvement,storage improvement,will be promoted and applied in enterprises.Combined with the logistics improvement measures proposed by the assembly workshop of N company,this paper has strong practical value and provides certain reference support for the improvement of logistics in the same industry.更多还原
