【摘要】：自中国加入WTO(世界贸易组织)后,中国的汽车物流业务的需求呈现快速增长的态势,使国家的整体利益有了最大的提高。一方面跨国车企提高在中国生产汽车零部件的国产化率,降低成本使之与国际水准接轨;另一方面通过全球采购,如韩国、墨西哥,汽车零部件大量进口,国内组装整车,通过外包物流降低其制造成本。在近几年的汽车工业发展中,零部件物流已经开始扭转了向更严格、更少量的库存发展的趋势,这种趋势在最近几年中帮助车企降低了成本。基于从控制"第三方利润源泉"的角度出发,汽车零部件库存管理逐渐被汽车制造商视为销售、生产、库存等的"总体系"的一环。因此,优化库存管理就显得尤为重要。本文主要借鉴系统动力学的思想,将VMI与TPL整合后的运作模式,与引入TPL前的VMI的模式对比,以供应链上游为背景,分别建立VMI模式与联盟式整合模式的系统动力学模型,通过模型阐释两种模式的特点和区别,建立各模式中变量的关系,构造各模式中的微分方程,利用Vensim软件对各系统动力学模型模拟分析,并选取供应商备货节奏、库存水平、客户服务水平以及牛鞭效应等指标,比较两种模式对供应链绩效的影响。本论文首先分析了供应链环境下汽车零部件库存的重要性,介绍了 VMI和TPL的基本理论,以A、B车企为例,对VMI与TPL整合后的运作模式,与引入TPL前的VMI的模式进行描述和简单比较。接着结合系统动力学相关理论,在假设一个供应商、一个第三方物流、一个汽车制造商和相同的市场需求环境下,构建了基于汽车零部件供应商和制造商的Vensim仿真模型。最后选取供应商备货节奏、库存水平、客户服务水平以及牛鞭效应等指标,分析两种模式对供应链绩效的影响,阐明了本论文所建立的VMI与TPL整合后的运作模式的有效性,同时对类似企业的库存供应链管理也具有实际的应用意义。
[Abstract]:Since China joined WTO (World Trade Organization), the demand of automobile logistics business in China has been increasing rapidly, and the overall interests of the country have been greatly improved. On the one hand, multinational auto companies increase the localization rate of auto parts produced in China, and reduce costs to bring them into line with international standards; on the other hand, through global procurement, such as South Korea, Mexico, large quantities of auto parts imports and domestic assembly of vehicles, Reduce manufacturing costs by outsourcing logistics. In recent years, parts logistics has begun to reverse the trend towards tighter, smaller inventories, which have helped automakers cut costs in recent years. Based on the view of controlling the "source of third-party profit", the inventory management of automobile parts is gradually regarded as a part of the "general system" of sales, production, inventory, etc. Therefore, the optimization of inventory management is particularly important. Based on the idea of system dynamics, this paper compares the operation mode of VMI and TPL with the model of VMI before introducing TPL, and establishes the system dynamics model of VMI mode and alliance integration mode, taking the upstream of supply chain as the background. This paper explains the characteristics and differences of the two models, establishes the relationship between the variables in each model, constructs the differential equations in each model, simulates and analyzes the dynamic models of each system by using Vensim software, and selects the supply rhythm and inventory level of the suppliers. Customer service level and bullwhip effect were compared between the two models on supply chain performance. This paper first analyzes the importance of automotive parts inventory in the supply chain environment, introduces the basic theory of VMI and TPL, and takes VMI and TPL as an example to analyze the operation mode of the integration of VMI and TPL. It is described and compared with the model of VMI before introducing TPL. Then, based on the theory of system dynamics, the Vensim simulation model based on automobile parts supplier and manufacturer is constructed under the assumption of a supplier, a third party logistics, an automobile manufacturer and the same market demand. In the end, the author analyzes the impact of the two models on the performance of supply chain, and illustrates the effectiveness of the integrated operation model of VMI and TPL, which is established in this paper, which is based on the rhythm of supplier inventory, inventory level, customer service level, bullwhip effect and so on, and analyzes the impact of the two models on the performance of supply chain. At the same time, the inventory supply chain management of similar enterprises also has practical application significance.
