【摘要】：巨大的汽车需求市场带动了汽车零部件市场的发展,然而我国汽车行业却面临着来自国内外两方面的竞争压力,“物流是第三利润的来源”,汽车零部件供应物流开始受到高度重视。引入VMI到汽车零部件供应物流系统,对汽车零部件供应物流系统则又提出了新要求。因此,需要站在系统的角度研究基于VMI的汽车零部件供应物流系统,以期降低汽车产业供应链上的生产运作成本,为提高汽车生产企业的竞争力寻找新突破。本文在总结前人研究成果的背景下展开对基于VMI的汽车零部件供应物流的模式研究和系统优化,集成考虑配送中心选址、库存策略及路径选择这三个重要问题,构建包含零部件配送中心选址、库存控制策略选择及配送路线安排的集成优化模型,并设计两阶段遗传算法来求解本文构建的数学优化模型,最后通过企业的实际运作案例检验了模型的有效性与算法的合理性。本文主要通过以下四个部分来研究基于VMI的汽车零部件供应物流的模式与系统的优化,具体内容如下:第一部分根据国内汽车零部件产业的发展现状,探讨国内汽车零部件供应物流中出现的问题,结合相关理论的研究与部分行业内少数企业实践的案例,提出将VMI引入到汽车零部件供应物流系统;第二部分分析引入VMI之后对汽车零部件供应物流模式产生的影响,对零部件配送中心选址、库存控制策略选择及配送路线安排这三个方面都提出了新要求;第三部分则是深入探究VMI模式下汽车零部件供应物流系统的优化问题,构建包含零部件配送中心选址、库存控制策略选择及配送路线安排的集成优化模型;第四部分设计两阶段遗传算法,以求解论文构建的模型,最后通过企业的实际运作案例来验证优化后零部件供应物流的总成本有了明显降低。
[Abstract]:The huge automobile demand market has driven the development of the auto parts market. However, the automobile industry in our country is facing the competition pressure from both domestic and foreign aspects. "Logistics is the third source of profit". Automobile parts supply logistics began to be highly valued. VMI is introduced into automobile parts supply logistics system, and new requirements for automobile parts supply logistics system are put forward. Therefore, it is necessary to study the automobile parts supply logistics system based on VMI from the point of view of system, in order to reduce the production operation cost in the automobile industry supply chain and find a new breakthrough in improving the competitiveness of automobile manufacturing enterprises. Under the background of summarizing the previous research results, this paper studies the model and system optimization of automobile parts supply logistics based on VMI, and integrates three important issues: location of distribution center, inventory strategy and path selection. An integrated optimization model including the location of parts distribution center, inventory control strategy selection and distribution route arrangement is constructed, and a two-stage genetic algorithm is designed to solve the mathematical optimization model constructed in this paper. Finally, the validity of the model and the rationality of the algorithm are verified by practical operation cases. This paper mainly through the following four parts to study the model and system optimization of automobile parts supply logistics based on VMI, the specific content is as follows: the first part according to the domestic automobile parts industry development present situation, This paper discusses the problems in domestic automobile parts supply logistics, and puts forward the introduction of VMI to the automobile parts supply logistics system by combining the research of relevant theories and the practice cases of a few enterprises in some industries. The second part analyzes the influence of the introduction of VMI on the logistics mode of auto parts supply, and puts forward new requirements for the location of the distribution center, the selection of inventory control strategy and the distribution route arrangement. The third part is to probe into the optimization of automobile parts supply logistics system in VMI mode, and construct the integrated optimization model which includes the location of parts distribution center, the selection of inventory control strategy and the arrangement of distribution route. In the fourth part, a two-stage genetic algorithm is designed to solve the model constructed in this paper. Finally, the total cost of the optimized parts supply logistics is reduced obviously through the actual operation cases of the enterprise.
