First-in-first-out (FIFO). Directs picking from the oldest inventory first.
Last-in-first-out (LIFO). Opposite of FIFO. I didn't think there were any real applications for this logic until a visitor to my site sent an email describing their operation that distributes perishable goods domestically and overseas. They use LIFO for their overseas customers (because of longer in-transit times) and FIFO for their domestic customers.
Pick-to-clear. Logic directs picking to the locations with the smallest quantities on hand. This logic is great for space utilization.
Reserved Locations. This is used when you want to predetermine specific locations to put away to or pick from. An application for reserved locations would be cross-docking, where you may specify certain quantities of an inbound shipment be moved to specific outbound staging locations or directly to an awaiting outbound trailer.
Maximize Cube. Cube logic is found in most WMS systems however it is seldom used. Cube logic basically uses unit dimensions to calculate cube (cubic inches per unit) and then compares this to the cube capacity of the location to determine how much will fit. Now if the units are capable of being stacked into the location in a manner that fills every cubic inch of space in the location, cube logic will work. Since this rarely happens in the real world, cube logic tends to be impractical.
Consolidate. Looks to see if there is already a location with the same product stored in it with available capacity. May also create additional moves to consolidate like product stored in multiple locations.
Lot Sequence. Used for picking or replenishment, this will use the lot number or lot date to determine locations to pick from or replenish from.
It’s very common to combine multiple logic methods to determine the best location. For example you may chose to use pick-to-clear logic within first-in-first-out logic when there are

multiple locations with the same receipt date. You also may change the logic based upon current workload. During busy periods you may chose logic that optimizes productivity while during slower periods you switch to logic that optimizes space utilization.
B.原文的翻译仓库管理系统（ WMS ）仓库管理系统（ WMS ）的演变与许多其他软件解决方案是非常相似的。最初的系统用来控制物料在仓库内的流动和贮存，仓库的作用正在延伸到包括轻型制造业，交通运输管理，订单管理，和完整的会计制度中。利用与先前的业务有关的软件，制造资源计划，作为一个比较，材料需求计划（ MRP ）开始作为一个规划要求，原材料的生产环境的系统。 物料需求计划很快演变成以MRP系统，补充调度和容量规划为基础的逻辑制造资源计划（ MRPII系统）。最终MRPII系统演变成企业资源规划（ ERP ），吸收所有的MRPII系统的功能包括充分的财务与客户和供应商管理功能。现在，无论仓库管理系统演变成一个以仓库为中心的ERP系统是一件好事或不可达的辩论。清楚的是，在仓库管理系统，企业资源规划，布局规划要求，交通运输管理系统，供应链计划，高级计划与排程，以及制造执行系统之间扩大重叠功能性只会增加那些寻找软件解决方案业务的公司混乱水平。论文网
尽管仓库继续获得额外的功能，最初的仓库管理系统的核心功能还没有真正改变。其主要目的是控制管理系统在工艺操作相关联的交易中的流动和材料储存。定向采摘，定向补充，定向收集是仓库的关键。从一个软件供应商到另一个在一个管理系统中详细的安装和处理可以有一个很大的差别，但是其基本逻辑将使用相结合的项目，地点，数量，度量单位，并以收集信息以确定在哪里储存，在哪里挑选，以及以何种顺序执行这些操作。
