多模块网格存储系统的待命位策略研究

Research on the Dwell Point Policy for Multi-module Grid Storage System

随着电子商务的发展以及土地价格的飞涨,较快的取货响应时间及较高的空间利用率成为了当前自动化仓储系统必须考虑的问题。为了应对电子商务新形势的发展,文章提出了一类既具有较快取货响应时间又有较高空间利用率的多模块网格存储系统,建立了多模块网格存储系统在三种待命位策略下的取货时间模型。通过仿真将其与KIVA系统相比,研究发现,第三种待命位策略取货效率大于其余两种,且随着系统规模的扩大,多模块网格存储系统的平均取货时间与KIVA系统相比慢3%到8%左右,但其空间利用率与货架容量远大于KIVA系统。

With the development of e-commerce and soaring land prices, faster pickup response time and higher space utilization have become the current automated warehousing system must be considered. In order to cope with the development of e-commerce, this paper proposes a kind of multi-module grid storage system with fast pickup response time and high space utilization, and establishes the pickup time model of multi-module grid storage system under three standby position strategies. Compared with KIVA system by simulation, it is found that the picking efficiency of the third standby location strategy is higher than the other two. With the expansion of system scale, the average picking time of the multi-module grid storage system is about 3% to 8% slower than that of KIVA system, but its space utilization and shelf capacity are much higher than that of KIVA system.
