【摘要】：人们对于汽车需求的大幅度提升,刺激汽车产业的快速发展,汽车产业的快速发展带来相互间竞争更加激烈。如何在激烈的产业竞争中,占得有利的地位,赢得更多消费者,是每个汽车制造企业面临的重大课题。作为汽车制造企业,降低成本必将使得市场竞争力得到大幅度提升。汽车制造企业的成本主要包括两个方面,一方面是汽车生产成本,一方面是零部件入厂物流成本。本文以汽车制造企业零部件入厂物流为研究对象,对于零部件入厂物流过程进行优化,旨在降低汽车制造企业的零部件入厂物流成本。汽车制造企业入厂物流成本包括管理成本、信息成本、运输成本以及仓储成本；其中,运输成本是入厂物流成本的主要部分。本文分析了汽车制造企业零部件入厂物流过程的各个环节,针对其环节中运输成本过高的因素,选择利用第三方物流企业对整条供应链进行规划,将原本由汽车制造企业编制的运输计划,转由3PL制定,提出带单边柔性时间窗的需求可拆分循环取货方法,以汽车制造企业为主导,第三方物流及供应商为配合的拉动式生产模式实现物流过程的整体优化。以WT汽车制造企业的实际数据,使用禁忌搜索算法进行实例验证,结果表明：提高了循环取货车辆的装载率,降低了汽车零部件入厂物流的运输成本,简化了入厂物流过程,提高了物流链的响应速度,实现了汽车制造企业与汽车零部件供应商双赢运营模式。同时,在Spyder环境下使用Python语言研发的信息系统的人机交互界面,实现了对于汽车零部件入厂物流车辆调度的实时性,为企业的零部件入厂物流实时调度起到关键作用。
[Abstract]:With the rapid development of automobile industry, the rapid development of automobile industry leads to more fierce competition. How to occupy a favorable position in the fierce industrial competition. Win more consumers, is each automobile manufacturing enterprise faces the major task. As an automobile manufacturing enterprise, reducing the cost will greatly improve the market competitiveness. The cost of automobile manufacturing enterprises mainly includes two aspects, one is the cost of automobile production. On the one hand, it is the logistics cost of parts entry. This paper studies the logistics of parts entry in automobile manufacturing enterprises, and optimizes the logistics process of parts entry. The purpose of this paper is to reduce the logistics cost of parts and components in automobile manufacturing enterprises. The logistics cost of automobile manufacturing enterprise includes management cost, information cost, transportation cost and storage cost. Among them, the transportation cost is the main part of the incoming logistics cost. This paper analyzes each link in the logistics process of the automobile manufacturing enterprise parts entry, aiming at the factors that the transportation cost is too high in the link. Choose to use the third party logistics enterprises to plan the entire supply chain, the transportation plan originally compiled by the automobile manufacturing enterprises, to be formulated by 3PL. In this paper, a split cycle method with unilateral flexible time window is proposed, which is dominated by automobile manufacturing enterprises. Third party logistics and suppliers to cooperate with the pull production mode to achieve the overall optimization of the logistics process. WT automobile manufacturing enterprise actual data, using Tabu search algorithm to verify the case. The results show that the loading rate of the vehicle is increased, the transportation cost of the logistics of the automobile parts and components is reduced, the process of the incoming logistics is simplified, and the response speed of the logistics chain is improved. At the same time, the man-machine interface of the information system developed by Python language under Spyder environment is realized. It realizes the real time of vehicle scheduling for automobile parts entry logistics, and plays a key role in the real time scheduling of enterprise parts entry logistics.
