【摘要】：汽车市场竞争日益激烈,客户需求呈多样化和个性化发展。汽车生产已从单一品种、批量化生产方式转化为多品种小批量的混流生产。混流生产对于零部件的供应提出较高的要求,如何在准确的时间将准确数量的零部件送到指定的地点是混流生产线零部件供应的一大难题。同步供货模式能最大程度降低零部件库存,是较为理想的供货模式。本文针对混流生产线零部件的同步供货模式,通过建模对如何实现零部件的同步供货进行研究,对于汽车制造企业混流生产线零部件同步供货的实际运作具有一定现实意义。本文在对混流生产线同步供货实际运作流程进行分析的基础上,首先从定性的角度对同步供货所适用的零部件类型进行划分,并分析同步供货实施的条件,提出同步供货实施的保障措施。其次,对同步供货模式的实施进行建模研究,通过分析同步供货的作业流程和运作环节,对初始模型进行优化,建立优化后的同步供货模型。再次,对影响同步供货的具体相关量进行建模分析,如车序采集量,送货频率,安全库存量等,同时应用排队论理论对同步供货运作中入厂卸货环节时间建模研究,相关量的研究有助于同步供货的顺利实施。最后,以M汽车制造企业的实际调研数据为基础,结合本文同步供货相关模型对其同步供货进行分析,并对现有供货情况提出改善措施。
[Abstract]:Automobile market competition is increasingly fierce, customer demand is diversified and personalized development. Automobile production has been transformed from single variety, batch production mode to multi-variety and small batch mixed-flow production. There is a high demand for the supply of parts in the mixed flow production. How to send the exact quantity of parts to the designated location in the accurate time is a big problem in the supply of the parts in the mixed flow production line. The synchronous supply mode can reduce the inventory of parts and components to the maximum extent, and it is an ideal mode of supply. According to the synchronous supply mode of parts in mixed-flow production line, this paper studies how to realize the synchronous supply of parts and components through modeling, which is of practical significance to the practical operation of synchronous supply of parts in mixed-flow production lines of automobile manufacturing enterprises. On the basis of analyzing the actual operation process of synchronous supply of mixed-flow production line, this paper firstly classifies the applicable parts and components of synchronous supply from a qualitative point of view, and analyzes the conditions for the implementation of synchronous supply. Put forward the guarantee measures for the implementation of synchronous supply. Secondly, the implementation of synchronous supply mode is modeled and studied. The initial model is optimized by analyzing the operation process and operation link of synchronous supply mode, and the optimized synchronous supply model is established. Thirdly, modeling and analysis are carried out on the specific related quantities that affect the synchronous supply, such as vehicle order collection quantity, delivery frequency, safe inventory and so on. At the same time, the queuing theory is applied to modeling the time of incoming and unloading links in the synchronous supply operation. The research of correlation quantity is helpful to the smooth implementation of synchronous supply. Finally, based on the actual survey data of M automobile manufacturing enterprises, this paper analyzes the synchronous supply model and puts forward the improvement measures to the existing supply situation.
