【摘要】：随着物流业的不断发展，越来越多的企业开始关注对物流运作的优化，以降低物流成本从而扩大利润的获得。而拣货作业成本更是因为占到配送中心整体运作成本60%以上而备受关注。而随着电子产品的高速更替，促使整个电子行业元器件供应链的采购模式进入“多频快”的方式。这也让连接上游电子原件生产商和下游终端制造商的电子元器件分销商更注重快速准确的提供配送服务以满足下游客户的供货需求。所以提高拣货作业的效率，降低作业成本更是各大元件分销配送中心运作中的最重要的课题。本文针对电子元件分销企业配送中心长期拣货效率低下，而拣货成本居高不下的问题，结合电子元件分销企业货物多为“整进散出”的特点，建立储位分配优化模型，引入存储时间周转率比的概念，，将货物的周转率与其在库的存放时间“合二为一”，提出贪婪算法对入库货物的储位分配进行优化，使得配送中心中行走时间短的储位得以被充分使用，降低作业人员在日常高频的拣货作业中行走距离，缩短拣货时间使得作业效率得以提高。
[Abstract]:With the development of logistics industry, more and more enterprises begin to pay attention to the optimization of logistics operation in order to reduce the cost of logistics and expand the profit. Picking cost is more than 60% of the overall operating cost of the distribution center and has attracted much attention. With the rapid replacement of electronic products, the procurement mode of components supply chain in the whole electronic industry has entered the mode of "multi-frequency fast". This also allows electronic component distributors that connect upstream electronic component manufacturers and downstream terminal manufacturers to focus more quickly and accurately on delivering services to meet downstream customers' supply needs. Therefore, improving the efficiency of picking operation and reducing the cost of operation is the most important task in the operation of distribution and distribution center of each major component. Aiming at the problem of low efficiency and high picking cost in electronic component distribution enterprise distribution center for a long time, combined with the characteristic that electronic component distribution enterprise's goods are mostly "in and out", an optimized model of storage distribution is established in this paper. This paper introduces the concept of storage time turnover ratio, combines the turnover rate of goods with their storage time in the warehouse, and proposes a greedy algorithm to optimize the storage allocation of incoming goods. So that the storage space with short walking time in distribution center can be fully used, reduce the walking distance of the operators in the daily high frequency picking operation, shorten the picking time to improve the efficiency of the operation.
