12、>　　1.4 Break bulk and cross dock </p><p>　　Break bulk and cross-dock warehouse operations are similar to a consolidation except that no storage is performed .A break bulk operation receives combined custo

13、mer orders from manufacturers and ships them to individual customers. The break bulk warehouse or terminal sorts or splits individual orders and arranges for local delivery. Because the long-distance transportation movem

14、ent is a large shipment, transport costs are lower and there is less difficult in tracking.</p><p>　　A cross-dock facility is similar to a break bulk facility except that it involves multiple manufacturers .

15、Retail chains make extensive uses of cross-dock operations to replenish fast-moving store inventories. For example, a retail cross-dock application .In this case, full trailer loads of product arrives from multiple manuf

16、acturers .As the product is received .it is either sorted by customer if it is labeled or allocated to customers if it has not been labeled. Product is then literally moved “</p><p>　　1.5 Processing/Postpone

22、<p>　　The direct economic benefit of this warehousing service is secondary to the fact that seasonal storage is essential to select businesses .For example , lawn furniture and toys are produced year-round and pri

25、 reduce costs. When a warehouse is primary justified on the basis of service, the supporting rationale is an improvement in the time and place capability of the overall logistical system .It is often difficult to quantif

26、y the return on investment of such a rationale because it involves cost-to-service tradeoffs .For example, placing a warehouse in a logistical system to service a specific market segment may increase </p><p>

27、;　　2. Stock management</p><p>　　All institutions, large or small, use components to build products of supplies to perform their work. They need to be able to track the quantities of the items that they have.

28、 In a manufacturing plant these items are components and products; in a library they are books, tapes, or records; in a clothing store they are clothes and accessories, etc .These institutions also need to be able to fin

42、現出來了。從概念的角度來看，沒有倉庫應包括在后勤系統(tǒng)，除非它完全以成本效益的基礎上合理的。然而，當各種系統(tǒng)職能交錯在一起時，倉庫主要的利益就被歸于單個的系統(tǒng)功能上了。</p><p><b>　　1.2經濟利益</b></p><p>　　倉庫的經濟利益當所有的后勤花費由于一種或多種的設備而直接減少體現出來時，量化該系統(tǒng)所獲得的經濟利益一點也不困難，因為它可以從系統(tǒng)運

43、作的成本對成本的利益互換中體現出來。例如，如果把一個倉庫加入到一個物流系統(tǒng)中將會減少所有的運輸費用，倉庫的固定成本和變動成本就會減少，這樣中的成本也就減少。當倉庫的總成本的減少能夠實現時，倉庫的經濟性的利益就體現出來了。四種經濟利益是拼箱，分類和交叉站臺，加工延期，庫存。每一個將在后面一一討論并舉例說明。</p><p><b>　　1.3拼箱</b></p><p>

44、;　　貨物拼箱是倉儲的一種經濟利益。在這種調配下，聯合倉庫可以從特定的需求者那里得到大量的制造原料，并有單獨的裝貨運輸。它的經濟利益是靠盡可能少的運輸比率和減少顧客收或碼頭的阻塞度來實現的。倉庫可以進行內向運輸和外像運輸，內向運輸是把貨物從制造商運輸到倉庫，外向運輸是把貨物從倉庫運輸到被客戶統(tǒng)一的大型碼頭上。舉個例字就是拼箱流。</p><p>　　為了提供有效的拼箱，每一個制造廠商必須把倉庫作為安全碼頭場所或作

45、為分類和裝配設備的場所。它主要的經濟利益就是把物流中單獨的幾個小的運輸聯結為特定的銷售市場。聯合倉儲是被單獨的企業(yè)所用，或是幾個商家聯合以來一起租用一個拼箱服務。通過這個項目，每個單獨的制造商或是發(fā)貨人比較喜歡較低的總配送成本。</p><p>　　1.4分類和交叉站臺</p><p>　　分類和交叉站臺的倉庫運作是與拼箱相似的一個運作類型，除了它們沒有存儲的操作。分類作業(yè)是將客戶按照制造

46、商和船務的順序結合成一個個客戶群。分類作業(yè)或是最終分類或分解成單獨的訂單，然后再在當地運輸給需求者。由于長途的運輸是一個大的貨物轉移，所以運輸成本會較低而且貨物跟蹤也較為容易。</p><p>　　交叉站臺設備是一個和分類操作類似的設備，除了它具有包含多個制造商的特點。通過交叉站臺來迅速補充存貨在零售連鎖店這方面得到了廣泛的運用。舉個例子，交叉站臺在零售連鎖上的應用，所有拖車從多重的制造商那里的裝載貨物。當貨物到

47、達時，貨物要不就是在已經有標簽的情況下按照客戶分組，或是在沒有被標簽的情況下分配給客戶。然后，貨物被精確的運到交叉碼頭被裝在到拖車上運往特定的客戶方，一旦拖車裝滿多重制造商的混和貨物時，拖車就被發(fā)往各連鎖零售商了。交叉碼頭的經濟利益包括滿載的拖車從制造上轉移到倉庫，再從制造商轉移到零售商，在貨物還沒有被儲存時，在交叉站臺設備上減少貨物搬運成本。</p><p><b>　　1.5加工延期</b&g

48、t;</p><p>　　通過延遲產品的處理過程或者減少生產活動，倉庫也能夠被延期使用。一直到實際需求信息獲得以前，一個倉庫都能以其包裝或貼標簽的能力來延遲最終產品的生成。舉例來說，蔬菜能夠在廠商那里進行加工處理罐裝并貼上“brights”的標簽。而Brights也被罐裝但卻是不貼標簽的。這個貼有brights字樣的專用標簽表示這一產品沒有必要去按照某一具體客戶的要求在工廠車間里進行定型的包裝了。一旦收到某個客戶

49、的訂貨要求，倉庫也能夠貼上標簽并進行最終包裝后來完成整個加工處理過程。</p><p>　　加工延期有兩個經濟利益。第一，風險將會減少。因為直到一個訂單需要有特定的標簽，而且包裹已經收到之前，貨物是不會被完全包裝的。第二，總庫存的標準可以通過對基本的產品標以多樣化的標簽或是包裝配置來決定。這種具有低風險和低庫存水平的聯合可以降低信息系統(tǒng)總的成本，因為，有時貨物在倉庫進行包裝的成本要比貨物在各自的制造商的設備上包裝

50、成本消耗的多。</p><p><b>　　1.6倉儲</b></p><p>　　相對與選擇交易的季節(jié)性倉儲是重要的這一事實，倉儲服務的直接經濟利益是次要的。例如，細布家具和玩具整年被生產，但主要在一個非常短的時期進行市場銷售。相對的，農業(yè)的產品在特定的時間被收割，卻將在隨后的一整年時間被消耗。兩種情況都需要倉儲對銷售的支持。倉儲提供一個允許強制調整物資資源和客戶資

51、源利用率的緩沖。</p><p><b>　　1.7服務利益</b></p><p>　　服務利益通過一個物流信息系統(tǒng)的倉庫可能能減少成本，也可能增加成本。當倉庫被證明是基礎服務的主要部分時。供應原理是在所有的物流信息系統(tǒng)中對于時間和空間容量的改進。因此，對于量化該理論帶來的獲得性的利益總是非常困難，因為它包括成本對服務的利益互換。舉例來說 , 將倉庫容進一個物流系統(tǒng)

52、中從而為某個特定的市場區(qū)域服務，這個可能增加會增加成本但是也可能增加市場份額，收入和總利潤。在一個概念上的水平，倉庫的服務利益是由它的有效利潤來證明的。 在一個操作的水平上，問題是該如何測量直接的收入沖擊。</p><p><b>　　2.倉庫管理器</b></p><p>　　所有機構，不管是大型的，還是小型的，都使用零部件來構建產品或供應其他商家。他們需要能夠跟蹤

53、物品的數量。在制造車間里，這些物品是零部件和產品；在圖書館里，它們是書，磁帶，或者是檔案；在服裝店里，它們是服裝及附屬物，等等。這些機構也需要能夠找到所需的物品。</p><p>　　在一個公司里，物品可能是正在制造或已經完成產品的原材料。貨物有損失或遭到破壞的可能。機構必須能夠跟蹤倉庫中物品的實際數目。其他功能單元可以改變物品的數量：例如，物品無論何時、何地遷移或使用時，應該更新其相應的庫存數量。</p&

54、gt;<p>　　倉庫和零部件/產品通過一個聚合關聯發(fā)生關系。庫存類中的數量屬性是倉庫與零部件/產品類的結合點，不同的鏈接，有不同的值。這個模型允許設計者定義不同類型的倉庫，作為單獨的物品集合；例如，零部件倉庫，產品倉庫。庫存的不同類型可以歸納為一個庫存類。</p><p>　　產品被劃分成兩個不同的類型：成品和用于制造產品的零部件。其他的劃分方法也是可能的。產品類中的“型號”屬性，用來作為一個唯一

55、的標識符，其他屬性描述了顧客選擇時可能用到的特征，如顏色等。零部件類具有物品序號，描述，類型等屬性，物品序號用來做唯一的標識符。產品和零部件通常是多-多的聚合關系，不過這與庫存模型無關.</p><p>　　物品類被劃分成產品和零部件子類的原因是：在這兩個實體的管理中，存在著很多不同。例如，產品是由一些零部件制成的，在制造過程中，庫存系統(tǒng)需要跟蹤零部件數量的變化。換句話說，零部件庫存比產品庫存更復雜。另一方面，兩

56、者又在一些方面有相同之處，例如，都需要跟蹤手頭數量（合計的總數量）和實際的存放位置。這里可以應用泛化關系，定義庫存類為一個父類，含有共同的特征，而產品庫存和零部件庫存類作為子類，含有每一種不同庫存類型的獨特特征。</p><p>　　當零部件或產品入庫時，通過調用add _ to _stock操作，它們的手頭數量增加。當零部件或產品出庫時，通過調用remove _ from _stock，它們的手頭數量減少。而a

57、dd _ to _stock操作根據預定的規(guī)則，決定物品放在哪兒。當零部件或產品被放到某個特定的倉庫區(qū)域時，操作add _ to _ local Stock增加局部的手頭數量。同樣的，remove _ to _ local Stock減少局部手頭數量。零部件或產品可以從一個倉庫區(qū)域遷移到另一個倉庫區(qū)域，操作transfer執(zhí)行這個動作。因為所有的移動操作既可以應用到零部件（由Component類表示），又可以應用到產品（由Product
