【摘要】：随着我国经济的不断发展以及经济的全球化，使得社会分工日益精细，市场竞争的激烈程度也日益加剧，人民生活节奏越来越快，其消费观也发生了巨大的变化，从大量消费逐渐变为样多品少的消费习惯。在现代经济飞速发展的大环境下，企业间的竞争不在是各自为政，已经上升到企业间联合的竞争模式，亦即供应链之间的竞争状态，本文建立在由供应商---配送中心---需求方构成的三级供应模式的供应链系统下，并从企业实现准时化配送的角度研究了零部件配送中心拣选作业这一重要的物流环节。首先从宏观的角度分析了汽车行业的不断发展及对零部件配送中心提出的挑战，针对文章的研究重点从微观的角度对学术界准时化配送及拣选作业的研究成果做了研究综述，然后介绍了配送中心六大职能及基本流程，，准时化配送及拣选作业的相关理论。在以上理论的基础之上对产前物流配送区分区拣选问题做出研究，首先介绍了该配送中心的物流配送系统，以实现拣选工作量均衡，工作时间均衡，少人化及配送至生产线的准时化这四大目标，采取零部件上线模式为SPS配送模式，并建立了以生产节拍（TT）为限制条件的储位指派及柔性分区的数学模型。在模型求解方面，提出基于零部件拣选频率排序的启发式算法，然后进行了实证分析，验证算法有效性并对企业的应用起了指导意义，实现零部件的JIT配送及整个广义生产链的利益双赢。
[Abstract]:With the continuous development of our economy and the globalization of economy, the social division of labor is becoming more and more fine, the fierce degree of market competition is becoming more and more intense, and the pace of people's life is getting faster and faster. Its concept of consumption has also undergone great changes, from a large number of consumption gradually to the consumption habits of more goods and less. In the rapid development of modern economy, the competition among enterprises is not to do their own thing. This paper is based on the three-level supply chain system, which is composed of the supplier -distribution center -demand side. And from the point of view of realizing punctual distribution of enterprises, this paper studies the important logistics link of the picking operation of spare parts distribution center. Firstly, it analyzes the continuous development of automobile industry and the challenge to the distribution center of spare parts from the macroscopic angle. This paper summarizes the research results of just-in-time distribution and picking operations in academic circles from the micro point of view, and then introduces the six functions and basic processes of distribution center. Theory of just-in-time distribution and sorting. On the basis of the above theory, this paper makes a research on the problem of prenatal logistics district selection. Firstly, this paper introduces the logistics distribution system of the distribution center, in order to achieve the balance of picking workload and working time. The four goals of less humanization and punctual distribution to production line are to adopt the online mode of parts and components as SPS distribution mode. A mathematical model of storage assignment and flexible partitioning with production beat TTs as the limiting condition is established. In the aspect of model solving, a heuristic algorithm based on picking frequency of parts is proposed, and then an empirical analysis is carried out to verify the validity of the algorithm and to guide the application of enterprises. Realize the JIT distribution of parts and the benefit of the whole generalized production chain.
