问答 仓储与配送科学-4.6.1 More

The working life of a warehouse management system is generally greater than that of the computer language in which it was written. Consequently, most WMS’s in current use are an accretion of many diff erent computer languages, including COBOL, PL1, Fortran, C, C++, SQL, and others. This can make them hard to maintain or customize.     Most WMS’s manage transactions but do n ot currently optimize anything. Instead, they are extremely configurable and let the user choose from among various rules to guide decision-making. But the client—or more likely a consultant—must choo...

The core of aWarehouse Management System (WMS) is a database of skus and a stock locator system so that one can manage both the inventory of skus and the inventory of storage locations. &nbs p;  There are significant opportunities to save labor when the system is expanded to include systems to direct receiving/put-away and/or order-picking. Additional systems are available to control ever finer detail within the warehouse as well as events ever farther up/downstream in the supply chain....

Warehouse Management Systems are extending their functionality out along the supply chain, both upstream and downstream, to include features that support collaboration. In this they are increasingly c ompeting with enterprise systems, which are trying to build specialization in warehouse management. WMS’s have an advantage in that they are already connected to financial systems and already hold in formation that is important to supply chain visibility and execution systems. The enterprise systems have advantages where they can grow out of a manufacturing enterprise, especially if the manufactur...

The next significant increase in functionality is to add a stock locator system. This is essentially the ability to manage an inventory of storage locations in addition to an inventory o f product. With this capability a software system can do more than trigger financial transactions but can finally support warehouse operations by directing warehouse activities to/from sto rage locations.    In addition, a WMS should also track the inventory of storage locations in the warehouse. A good WMS will track every place that product can be, ...

The most fundamental capability of a WMS is to record receipt of inventory into the warehouse and to register its shipment out. This is fundamental because it drives essential financial tran sactions: receipt drives the paying of bills to suppliers upstream;and shipping drives the sending of invoices downstream to the consignee. This is the base from which modern, complex WMS’s have grown....

Many warehouses also must handle returns, which run about 5% in retail. This will become a major function within any warehouse supporting e-commerce, where returns run 25–30%, comparable to those supp orting catalog sales.    Another trend is for warehouses to assume more value-added processing (VAP), which is additional work beyond that of building and shipping customer orders. Typical value-added processing includes the following: Ticketing or labeling (For example, New York state requires all items in a pharmacy to be price-labeled and many distributors do this while picking the items 30 CHA...

问答 仓储与配送科学-3.5 Shipping

Shipping generally handles larger units than picking, because packing has consolidated the items into fewer containers (cases, pallets). Consequently, there is still less labor here. There m ay be some walking if product is staged before being loaded into freight carriers.    Product is likely to be staged if it must be loaded in reverse order of delivery or  if shipping long distances, when one must work hard to completely fill each trailer. Staging freight creates more work because staged freight must be double-handled.    The tr...
