【摘要】：针对企业内普遍存在的生产线物料过早配送或不及时造成的库存积压、缺货问题，为了减少各物流环节库存，降低总配送成本，研究了基于看板的生产线物料循环配送方式，并加以时间窗约束，使得配送作业实现在必要的时间向必要的地点送达必要量的物料。同时为了保障该循环配送方式有效实施，研究了生产线物料均衡化消耗问题。主要有以下部分内容。第一章阐述了物料配送问题的研究背景和研究意义，指出在当前背景下该研究的重要性，总结了国内外关于入厂物流和厂内物流生产线配送的研究现状，得出该问题当前的研究状况与不足，介绍了本文的研究思路、研究内容及创新点。第二章按照本文的研究思路总结了相关理论知识，首先介绍了准时化物流的相关概念，再将该思想融入到厂内物料供给问题中，进而介绍了看板及其使用规则，最终依据均衡化生产提出均衡化消耗的概念。第三章首先对国内外研究循环配送方式的文献进行综述，，确定本文研究的生产线物料循环配送流程；其次进行参数分析并建立基于看板的生产线物料循环配送数学模型，通过求解得出使配送成本最小的物料配送循环时间，进而分析线边库存量和该配送方式下看板数量的计算方法；最后为了避免配送作业过早或延迟进行，提出利用时间窗约束作业的起始和结束时刻，建立数学模型，并分析确定相应循环配送模式下员工数量。第四章首先对均衡化生产进行概述，相应均衡化生产概念提出生产线物料均衡化消耗概念，并列出保证均衡化消耗的前提，分析了零件器具容量对均衡化消耗的影响，建立物料均衡化消耗数学模型，运用遗传算法对模型进行求解，得出保障物料均衡化消耗的最优器具容量值。
[Abstract]:In order to reduce the inventory of each logistics link and reduce the total distribution cost, the method of material circulation distribution in production line based on Kanban is studied in view of the overstock and shortage of material in production line caused by premature distribution of production line material or not in time, in order to reduce the inventory of each logistics link and the total distribution cost. The time window is used to realize the delivery of the necessary amount of material to the necessary place at the necessary time. At the same time, in order to ensure the effective implementation of the circular distribution mode, the production line material equalization consumption problem is studied. There are the following parts. The first chapter describes the research background and significance of the material distribution problem, points out the importance of the research under the current background, summarizes the domestic and foreign research status of in-plant logistics and in-plant logistics production line distribution. The current research situation and deficiency of this problem are obtained, and the research ideas, contents and innovations of this paper are introduced. The second chapter summarizes the relevant theoretical knowledge according to the research ideas of this paper. Firstly, it introduces the concept of punctual logistics, and then integrates this idea into the material supply problem, and then introduces the Kanban and its usage rules. Finally, the concept of equalization consumption is put forward according to equalization production. The third chapter firstly summarizes the literature of domestic and foreign research on circulation distribution mode, determines the material circulation distribution flow of production line studied in this paper; secondly, carries on the parameter analysis and establishes the mathematical model of production line material circulation distribution based on Kanban. Through solving, the material distribution cycle time with minimum distribution cost is obtained, and then the calculation method of line side inventory and the number of Kanban under the distribution mode is analyzed. Finally, in order to avoid the premature or delayed delivery operation, This paper presents a mathematical model based on the time window to constrain the start and end time of the operation, and analyzes and determines the number of employees in the corresponding circulation distribution mode. The fourth chapter summarizes the equalization production, puts forward the production line material equalization consumption concept, lists the premise of ensuring the equalization consumption, and analyzes the influence of the parts capacity on the equalization consumption. The mathematical model of material equalization consumption is established, and the genetic algorithm is used to solve the model.
