很多公司的基础运营离不开eRP（eRP：企业资源计划）的应用。就企业内外物流活动而言，eRP是否合适的关键在于其WMS（WMS：仓储管理系统）功能是否完善。为了满足现代仓储的需求，众多的eRP研发商也开始逐步增加WMS功能到其各自的系统中去。BY ROBeRTO MICHeL,eDITOR AT LARGe 郑承毅翻译一个企业资源管理系统（eRP）能将企业运营的关键数据一起协同处理，其中包括客户订单，生产计划，配送计划以及财务管理等等。但eRP在很多环节上的细节处理，仍有很多不足。虽然eRP的基础功能已经得到了很好地应用，但一些功能依然需要持续的改善。在对仓储管理系统（WMS）的需求上，便是很多公司迫切需要的。但尽管许多eRP研发商已经研发了WMS功能作为他们的软件模块的一部分，或者已经收购了WMS研发商，但最优秀的WMS研发商并没有停止研发的步伐，研发出的新功能涵盖了劳务管理，数据分析，零售操作系统等，并不断完善用于WMS与自动化设备之间的仓库控制系统（WeS）尽管今天eRP系统可以做到许多，但eRP供应商仍然需要一个强有力的战略来解决公司的供应链执行需求。他们要么必须在以前不属于eRP的功能上构建，要么在双系统集成方面变得非常灵活。虽然成熟的eRP研发商的软件都有广泛和深入的供应链管理功能，功能即使包括WMS功能在内，但依仍无法满足大量用户不断出现的业务需求。供应链...; 关注问题 3  1  0评论

分拣场，我被分配到了小件分拣组，晚上就来这里报到。原本以为，工作12个小时不可能每一秒都在忙，试工的第一晚，我还揣了个Kindle，想着闲下来时可以读些书。但万万没料到，那天晚上我从开始干到结束，连打开Kindle的机会都没有。在分拣场等待开工的夜班工人。郭嘉亮摄晚上的分拣场和白天是两个样，白天时场内阒寂无人，晚上则一片灯火通明，到处人影憧憧。登上工作台后，一阵延绵而沉闷的轰隆声从远处传来，原来是几十上百辆电叉车同时碾轧地面时发出的声音。还不到晚上7点，早到的人有的在玩手机，有的趴在工作台上休息，没人来和我介绍一下情况。他们似乎都不大喜欢说话，我于是自顾自四处打量。整个分拣场就像一个大埠头，货车在地面穿梭，工人在1米高的工作台上干活。工作台约莫有8到10个足球场那么大，四周是一个个编了号的装卸货口，一排排货车屁股朝着工作台停靠，打开后厢门装卸货物。这些是营业门市白天揽收的快件。我们的工作，就是把这些快件按照目的地重新分拣，然后用纤维袋分别打包运走。分拣场全景。作者供图很快就开工了，组长让我负责分拣环节的第一步——“倒包”。从门市营业点送来的快件是用纤维袋打包好的，“倒包”就是把袋子割开，把快件倒出来。一旁的补码员会用红外枪扫描快递单上的条码，再按目的地补上手写编码，然后把快件扔上传送带。他们的动作干脆利落，马克笔划拉得飞快，开始的时候，我尽了最大努力也跟不上。 ...; 关注问题 1  2  0评论

felix 发起了提问 2020-06-09 22:38 书籍推荐 蚂蚁拣货法 Bucket Brigade 方法论 仓储与配送科学: 问答仓储与配送科学前言

WAReHOUSe&DISTRIBUTION SCIeNCe本书的主题是仓库布局和作业的科学。我们之所以称之为“科学”，是因为我们为此建立了数学和计算机模型。当前太多的仓储实践都是基于经验法则和简单的比率。就目前而言，这很好。但是还有更多的事情可以做。大多数仓库都有详细的记录，准确记录每个客户的订单详情和时间。通常，该数据由IT部门作为财务报告的一部分来提供；但是这些数据可以在作业上对仓库布局和操作进行“调整”为适应客户订单的最佳模式。本书将向您展示如何做到这点。还有其他有关仓储的书籍，但它们大多只限于列出设备类型，拣选方法等。这是必要的，也做的很好。但是这里的重点不是分类法，而是关于优化仓库作业的方法论。本书在另一方面也与众不同：我们试图避免昂贵且缺乏灵活性的整体式优化模型。相反，我们采用强调决策权下放的方法。例如，在仓库中分配空间时，我们将要求每个SKU制定一份 “业务计划”，其中详细说明了其所占用空间和对等将产生的经济利益；然后我们将根据最佳回报对SKU进行排名。商业计划很可能是数学模型，但是分配过程只是从排序列表中完成，这种方法使用起来非常简单。实际上，人们可以动态地做出决策，将空间重新分配给当前的最佳产出者。诀窍是价值匹配。最终，可以看到托盘、箱子、单件等商品都可能像通勤者一样穿过配送中心，每个人都知道商品的尺寸和特殊处理要求。他们可能会与周围的环境...; 关注问题 2  0  0评论

1.1 Why have a warehouse?Why have a warehouse at all? A warehouse requires labor, capital (land and storage-and-handling equipment) and information systems, all of which are expensive. Is there some w ay to avoid the expense? For most operations the answer is no. Warehouses,or their various cousins, provide useful services that are unlikely to vanish under the current economic scene. Here are some of their uses:To better match supply with customer demand: One of the major challenges in managing a supply chain is that demand can change quickly, but supply takes longer to change.

Warehouses may be categorized by type, which is primarily defined by the customers they serve. Here are some of the more important distinctions: A retail distribution center t ypically supplies product to retail stores, such as Wal- Mart or Target. The immediate customer of the distribution center is a retail store, which is likely to be a regular or even captive customer , receiving ship- ments on regularly scheduled days. A typical order might comprise hundreds or thousands of items; and because the distribution center might serve hundreds of stores, the flow of prod...; 关注问题 3  0  0评论

Material flowHere we briefly discuss a few issues that help lay the foundations for warehouse analysis.The most fundamental idea is of the management of two resources: space and time (that is, la bor or person-hours).The fluid model of product flow The “supply chain” is the sequence of processes through which product moves from its origin toward the customer. In our meta phor of fluid flow we may say that warehouses represent storage tanks along the pipeline. The analogy with fluid flows can also convey more substantial insight.

even though it is a frequently useful metaphor, most products do not, of course, flow like incompressible fluids. Instead, they flow more like a slurry of sand and gravel, roc ks and boulders. In other words, the product is not infinitely divisible but rather is granular at different scales. A stock keeping unit, or SKU, is the smallest phys ical unit of a product that is tracked by an organization. For example, this might be a box of 100 Gem Clip brand paper clips. In this case the final customer will use a still smaller unit (ind...; 关注问题 2  0  0评论

felix 发起了提问 2020-06-14 12:45 仓储与配送科学: 问答仓储与配送科学-2.3 Two fundamental resources

Warehouse management is all about careful use of space and time (that is, labor or person-hours). Both space and time are expensive and so one would like to use as little of each as possible in delivering product to customers. Figure 2.3 shows a plot of the popularity (number of times requested, or picks) of each SKU of a warehouse together with the physical volume (flow) of the SKU moved through the warehouse during one month. There is little correlation between popularity and flow, and this is one of the challenges of warehouse management, bec...; 关注问题 2  0  0评论

In addition, storage locations are typically within specialized equipment, such as shelving or flow rack, which are a capital cost. These costs impel us to use storage space as efficien tly as possible.There are two main strategies used in storing product. The simplest is dedicated storage, in which each location is reserved for an assigned product and only that prod- uct may b...; 关注问题 2  0  0评论

A queuing system is a model of the following structure: Customers arrive and join a queue to await service by any of several servers. After receiving service the customers depart the system.A fundame ntal result of queuing theory is known as Little’s Law, after the man who provided the first formal proof of a well-known piece of folk-wisdom [36].Theorem 2.1 (Little’s Law). For a queuing system i n steady state the average length L of the queue equals the average arrival rate λ times the average waiting time W. More succinctly:L = λW.A warehouse may be roughly modeled as a queuing system in wh...; 关注问题 2  0  0评论
