For each unit-of-measure, state whether there are any standardized dimensions an d, if so, identify them.Question 2.2. In what ways has the inventory process depicted in Figure 2.5 been idealized?Question 2.3. What are the advantages and disadvantages of dedicated (reserved)& nbsp;storage? Of shared (random) storage?Question 2.4.

A warehouse reorganizes and repackages product. Product typically arrives packaged on a larger scale and leaves packaged on a smaller scale. In other words, an important function of this warehouse is to break down large chunks of product and redistribute it in smaller quantities. For example, some skus may arrive from the vendor or manufac- turer in pallet quantities but be shipped out to custome rs in case quantities; other skus may arrive as cases but be shipped out as eaches; and some very fast-moving skus may arrive as pallets and be shipped out as eaches. In such an...; 关注问题 2  0  0评论

Receiving may begin with advance notification of the arrival of goods. This allows the warehouse to schedule receipt and unloading to coo¨rdinate efficiently with other activities within the warehous e. It is not unusual for warehouses to schedule trucks to within 30-minute time indows. Once the product has arrived, it is unloaded and possibly staged for put away. It is lik ely to be scanned to register its arrival so that ownership is assumed, payments dispatched, and so that it is known to be available to fulfill customer demand. Product will be inspected and any excep...; 关注问题 2  0  0评论

felix 发起了提问 2020-06-15 14:08 仓储与配送科学: 问答仓储与配送科学-3.2 Put-away

Before product can be put away, an appropriate storage location must be determined.This is very important because where you store the product determines to a large extent how quickly and at what cost you later retrieve it for a customer. This requires managing a second inventory, not of product, but of storage locations. You must know at all times what storage locations are available, how large th ey are, how much weight they can bear, and so on. When product is put away, the storage location should also be scanned to record where the product has been placed. This in...; 关注问题 1  0  0评论

felix 发起了提问 2020-06-15 14:27 仓储与配送科学: 问答仓储与配送科学-3.3 Order-picking

On receipt of a customer order the warehouse must perform checks such as verifying that inventory is available to ship. Then the warehouse must produce pick lists to guide the order-picking. Finally, it must produce any necessary shipping documentation and schedule the order-picking and shipping. These activities are typically accomplished by a warehouse management system, a la rge software system that co¨ordinates the activities of the warehouse. This is all part of the support to expedite the sending of the product to the customer. Order-picking...; 关注问题 2  1  0评论

felix 发起了提问 2020-06-15 15:48 仓储与配送科学: 问答仓储与配送科学-3.3.1 Sharing the work of order-picking

A customer order may be picked entirely by one worker; or by many workers but only one at a time; or by many at once. The appropriate strategy depends on many things,but one of the most important is how quickly must orders flow through the process.For example, if all the orders are known before beginning to pick, then we can plan efficient picking strategies in advance. If, on the other hand, orders arrive in real time and must be picked in time to meet shipping schedules then we have little or no time in which to seek efficiencies. A general decision to be mad...; 关注问题 2  0  0评论

felix 发起了提问 2020-06-15 15:53 仓储与配送科学: 问答仓储与配送科学-3.4 Checking and packing

Packing can be labor-intensive because each piece of a customer order must be handled; but there is little walking. And because each piece will be handled, this is a convenient time to check that the customer order is complete and accurate. Order accuracy is a key measure of service to the customer, which is, in turn, that on which most businesses compete. &nbs p;Inaccurate orders not only annoy customers by disrupting their operations, theyalso generate returns; and returns are expensive to handle (up to ten times the cost ofshipping the product out). ...; 关注问题 2  3  0评论

felix 发起了提问 2020-06-15 15:55 仓储与配送科学: 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...; 关注问题 2  0  0评论

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...; 关注问题 2  0  0评论

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....; 关注问题 2  0  0评论
