【摘要】：为了适应市场需求,混流生产模式成为大势所趋。然而,混流生产模式对于产品的物料运输要求较高,因为这决定了汽车生产线中的物流成本和效率。因此,降低物流运输成本、提高物流运输效率将是研究的首要问题。由此可知,为了降低物流运输成本和提高物流运输效率,应对现有的物流技术进行优化改造的专项研究。本文就此进行了深度分析。首先,本文详细阐明了汽车混流生产中物料输送的基本理论,找出了现有物流体系中三个主要层面(作业层面、规划层面和计划层面)存在的问题;其次,本文对现有的这些问题作出了成因分析,并以此为根据确定了物料输送体系的优化方向,与此同时,依据JIT生产方式衍生出了更符合实际生产物流需求的JITD物料输送理论,综合优化方向和JITD,在理论层面提供了一套详细的优化方案,其中包括物料存储、物料输送、信息管理和物流流程等优化措施。最后,将东风日产郑州工厂总装车间内饰线作为研究对象,找出生产现场物料输送存在的实际问题,以理论优化方案为支撑,为总装内饰线提供物料区集配、AGV牵引以及上下线机构等三个方面的优化策略,并对优化结果给予分析和评价。本文不仅在理论上对物料输送体系进行了优化,而且还结合了理论优化方案,对实际生产线进行了优化改造。结果表明,本文针对物料输送体系的优化,在降低物流成本的同时还提高了作业效率。
[Abstract]:In order to meet the needs of the market, the mixed production model has become the trend of the times. However, the mixed production mode requires high material transportation because it determines the logistics cost and efficiency in the automobile production line. Therefore, reducing the cost of logistics transportation and improving the efficiency of logistics transportation will be the primary problem. Therefore, in order to reduce the cost of logistics transportation and improve the efficiency of logistics transportation, the existing logistics technology should be optimized and reformed. In this paper, a deep analysis is carried out. Firstly, this paper expounds the basic theory of material transportation in automobile mixed flow production, and finds out the existing problems in the three main levels of logistics system (operational level, planning level and planning level). Secondly, this paper makes an analysis of the causes of these problems, and determines the optimization direction of the material transportation system based on this, at the same time, According to the JIT mode of production, the theory of JITD material transportation, which is more suitable to the actual production logistics demand, is derived. The optimization direction and JITD, provide a set of detailed optimization schemes at the theoretical level, including material storage, material transportation, etc. Information management and logistics process optimization measures. Finally, taking the interior line of the assembly workshop of Zhengzhou factory of Dongfeng Nissan as the research object, finding out the practical problems existing in the material transportation in the production site, taking the theoretical optimization scheme as the support, providing the material area distribution for the assembly inner decoration line. The optimization strategies of AGV traction and upper and lower line mechanism are analyzed and evaluated. This paper not only optimizes the material conveying system theoretically, but also optimizes the actual production line by combining the theoretical optimization scheme. The results show that the optimization of material delivery system not only reduces the cost of logistics, but also improves the efficiency of operation.
