隨(sui)著國內經濟的發(fa)展，特別(bie)是物流業的突飛猛(meng)進，越(yue)來越(yue)多(duo)的企業正在經歷著由傳統(tong)的平面倉庫向立(li)體倉庫發(fa)展的過(guo)程。

從經(jing)營(ying)理(li)(li)念、物流運作模式等方面(mian)來看，平(ping)面(mian)倉(cang)庫(ku)和立體(ti)倉(cang)庫(ku)有著(zhu)很大(da)的區(qu)別。立體(ti)倉(cang)儲(chu)系統由(you)于其(qi)具有很高的空間利用率，很強的入出庫(ku)能力(li)，采用計算機(ji)進行控制管理(li)(li)而利于企業(ye)實施現(xian)代化(hua)管理(li)(li)等特點，已(yi)成(cheng)為企業(ye)物流和生產管理(li)(li)不可缺少的倉(cang)儲(chu)技術，越來越受到企業(ye)的重(zhong)視。

倉(cang)(cang)儲物(wu)流設(she)備(bei)(bei)是指在倉(cang)(cang)儲管(guan)理過程中使(shi)用到的硬件(jian)(jian)設(she)施和信息(xi)管(guan)理軟件(jian)(jian)系(xi)(xi)統(tong)(tong)，其結構主要包(bao)括立體貨架(jia)、堆(dui)垛機(ji)、室內搬運(yun)車(che)、出入輸(shu)送設(she)備(bei)(bei)、分揀系(xi)(xi)統(tong)(tong)、升降設(she)備(bei)(bei)（提(ti)升機(ji)或升降機(ji)）、以及計算機(ji)管(guan)理和監控系(xi)(xi)統(tong)(tong)。這些設(she)備(bei)(bei)可以組(zu)成半自(zi)動(dong)化(hua)(hua)、自(zi)動(dong)化(hua)(hua)、機(ji)械化(hua)(hua)的倉(cang)(cang)庫，來堆(dui)放、存取和分揀物(wu)品
