【摘要】：依必安派特是一家传统的制造型企业,主要设计、制造和销售工业用风机。近年来公司面临激烈的市场竞争,公司利润降至历史低点。降低运营成本,提升企业竞争力成为公司的应对策略。本文从工厂物流角度研究实现公司策略的方法。文章选取AC40产线作为工厂物流改善的研究对象。经研究AC40产线的工厂物流主要存在两大问题:1)物料配送方法不科学。所有的物料都按照生产订单从仓库领用,造成物料配送成本高,产线物料库存高;2)设备按照机群方式布置,产品批量流动。机群式布置方法占用过多的生产面积,而且订单生产周期也过长。仓库到车间物料配送方法的改善研究是通过对物料进行分类,按照领用频次和年消耗金额(ABC分类)把物料分成7个类别。并根据每类物料的特点采用不同的配送方案,有看板拉动的、有安全库存促发的、还有根据订单直接配送的。改善后物料的配送方法更加科学,重要性高的物料被分配到更多的管理资源,而重要性较低物料的管理成本大大降低了。文章研究了设备垂直布置方法(设备按照工序顺序布置)的优点。AC40产线设备在按照垂直布置方法重新安排后,工序之间的大量库存得到消除,工序之间基本能做到一件流或一盒流。同时文章对瓶颈工序进行了定义和分析,通过瓶颈工序的消除,工序之间的产能达到平衡,减少了工序之间的产成品库存。最后,文章从产线库存金额、订单生产周期、生产物流距离、占用生产面积等几个方面论证了改善的效果。
[Abstract]:Yibianpaite is a traditional manufacturing enterprise that mainly designs, manufactures and sells industrial fans. In recent years, the company has faced fierce market competition, its profits have fallen to a historic low, and its operating costs have been reduced. This paper studies the method of realizing the company strategy from the point of view of factory logistics. This paper selects AC40 production line as the research object of the improvement of factory logistics. There are two main problems in the factory logistics of line:. 1). Material distribution method is not scientific. All materials are received from warehouse according to production order. The cost of material distribution is high and the inventory of material in production line is high; 2) the equipment is arranged according to the cluster mode, and the products are flowing in batches. The cluster layout method takes up too much production area. And the order production cycle is also too long. Warehouse to workshop material distribution method improvement research is through the classification of materials. According to the usage frequency and the annual consumption amount (ABC classification), the materials are divided into seven categories. According to the characteristics of each kind of materials, different distribution schemes are adopted, with Kanban pulling and safety inventory promoting. There are also direct distribution according to orders. Improved material distribution methods are more scientific, high-importance materials are allocated to more management resources. The management cost of the less important materials is greatly reduced. This paper studies the vertical arrangement of the equipment (the equipment is arranged according to the process order). The AC40 production line equipment is rearranged in accordance with the vertical arrangement method. A large amount of inventory between processes can be eliminated, and one piece flow or a box flow can be achieved between the processes. At the same time, the article defines and analyzes the bottleneck process, through the elimination of the bottleneck process. The balance of production capacity between processes reduces the inventory of finished products between processes. Finally, the article from the production line inventory amount, order production cycle, production logistics distance. The effect of improvement is demonstrated in several aspects, such as occupation of production area.
