Abstract

Since their introduction, automated storage and retrieval systems (AS/RS) give a better solution for the inventory management in industrial companies and distribution centres to improve theirs performances. The main objective of the paper is to offer a performance comparison between two kinds of AS/RS (Free-Fall flow-rack and classic flow-rack), to highlight the benefits of using FF-flow-rack AS/RS in warehousing systems. Three comparison parameters has been considered: the average retrieval-travel-time, the total retrieval-travel-time, and throughput of a customer request. For this, multiple simulations are performed for different rack configurations with the same characteristics of both systems. The obtained results show that using the FF-flow-rack in place of the classic flow-rack will greatly decrease the average retrieval-travel-time and the total retrieval-travel-time of customer request. Indeed, the improvement of the throughput in the FF-flow-rack AS/RS can reach around 90% compared to the throughput in the classic flow-rack AS/RS.

自动存储和检索系统:自由落体流架与经典流架的性能比较

自引入以来，自动存储和检索系统(AS/RS)为工业公司和配送中心的库存管理提供了更好的解决方案，以提高他们的绩效。本文的主要目的是提供两种AS/RS(自由落体流架和经典流架)的性能比较，以突出在仓储系统中使用FF-flow-rack AS/RS的好处。考虑了三个比较参数:平均检索旅行时间、总检索旅行时间和客户请求的吞吐量。为此，对两种系统具有相同特性的不同机架配置进行了多次仿真。研究结果表明，用FF-flow-rack代替经典flow-rack可以大大降低客户请求的平均检索行程时间和总检索行程时间。实际上，与传统流架AS/RS相比，ff流架AS/RS的吞吐量提高了90%左右。
