【摘要】：仓储在物流与供应链中占有一个非常重要的地位,在生产制造企业、第三方物流企业以及生产配送中心都占有举足轻重的作用。据统计,在所有仓储作业中,仅拣选就占据了整个仓储操作成本的50%-75%。订单拣选是为了响应客户订单需求,而从存储区域或缓冲区收集货物的作业工程,在人工作业仓储系统中,订单拣选是最消耗人力成本的运动环节,而在自动化仓库中,则是最消耗资源成本的运作环节。为了将拣选成本降到最低,需要对仓库中的产品或者货物进行货位分配。论文主要以华中科技大学物联网研究中心为背景,针对物联网研究中心的仓储环境研究适用于该中心的仓储货位分配策略,并实现了仓储管理的信息化、数字化。仓储管理系统货位分配主要从基于产品频度的入库货位分配与基于偏离度的订单拣选两个方面来进行研究。仓储管理系统货位分配关注以下问题:(1)产品入库货位分配时主要考虑基于产品频度的货位分配原则。产品在进行货位分配时首先要进行入库货位分配,文章在产品入库货位分配时提出了产品频度的概念。传统的货位分配优化只是针对出库货位分配进行了优化,而对于入库货位分配优化研究的则不多。(2)产品出库货位分配时利用入库货位分配的结果进行检索,拣货点位置确定后,利用基于偏离度的通道访问策略对产品进行拣选。传统的货位分配并没有将入库货位分配与出库货位分配相结合,文章主要是研究出库货位与入库货位结合之后的货位分配优化。仓储管理系统中的货位分配在整个仓库作业中占有重要的地位,货位分配的结果不仅影响着仓库的作业效率以及整个仓库的成本,而且还影响着仓库中产品的控制与管理。合理的货位分配策略不仅能够方便仓库作业人员管理库存,而且能够提高仓库的作业效率,节省企业的成本。基于产品频度的入库货位分配策略以及基于偏离度的订单拣选策略,保证拣选距离最短,减少叉车行走距离,提高仓库拣选效率,降低仓库拣选成本。
[Abstract]:Warehousing plays a very important role in logistics and supply chain, and plays an important role in manufacturing enterprises, third-party logistics enterprises and production and distribution centers. In the human work warehouse system, order picking is the most labor-consuming activity, while in the automated warehouse, it is the most resource-consuming operation. In order to reduce the picking cost to the lowest, it is necessary to grade the goods or goods in the warehouse. Based on the research center of the Internet of Things of Huazhong University of Science and Technology, this paper studies the storage environment of the research center of the Internet of Things, which is suitable for the center's warehouse allocation strategy, and realizes the informationization and digitization of the warehouse management system. Two aspects of order picking are studied. The allocation of warehouse management system is concerned with the following issues: (1) The allocation principle based on product frequency is mainly considered in the allocation of product storage space. The concept of degree. The traditional optimization of location allocation only aims at the optimization of outbound location allocation, but there are few studies on inbound location allocation optimization. (2) When product outbound location allocation is searched by the results of inbound location allocation, the product is sorted by channel access strategy based on degree of deviation. The traditional location allocation does not combine the inbound location allocation with the outbound location allocation. This paper mainly studies the optimization of location allocation after the combination of outbound location and inbound location. Operational efficiency and the cost of the whole warehouse also affect the control and management of the products in the warehouse. Reasonable location allocation strategy can not only facilitate the warehouse operators to manage the inventory, but also improve the operational efficiency of the warehouse and save the cost of the enterprise. Single picking strategy ensures the shortest picking distance, reduces forklift walking distance, improves the efficiency of warehouse picking, and reduces the cost of warehouse picking.
