疫情冲击显示工作人力是零售业供应链最脆弱的一环，需提升自动化程度。法新社为了解COVID-19(新冠肺炎)疫情造成零售业市场变化的因应之道，美国自动化供应链软件大厂Blue Yonder与英国华威制造集团(WMG)调查美洲、亚洲、欧洲105个各类零售商供应链资深主管，结果显示未来须强化供应链以因应类似变局。 &nbs p; 根据Retail Systems报导，疫情带给零售业各种新挑战，某些特定商品出现大量需求，其他商品却乏人问津；有些商店被迫关闭或须在符合安全社交距离的前提下运作；拓展在线购物业务虽可行，但非一蹴可几，还需克服相关营运挑战。经过疫情洗礼，零售商发现人类员工是供应链最脆弱的一环，须提升自动化、弹性、敏捷度、强固性、透明度以强化供应链的适应性，而人工智能(AI)与机器学习等先进技术，则可望成为零售商因应未来破坏与变局，兼顾满足客户期待的关键利器。疫情期间零售商供应链遭遇的瓶颈中，工作人力是最大的挑战，因员工受检疫或染疫影响，造成营运关闭或需聘雇临时员工的仓储与商店各占59%与48%，提高自动化程度或为解方。此外，46%的零售商认为供货商生产与配送量能信息不够透明，44%认为消费者需求缺乏能见度。经零售商实证，供应链因应疫情最有效的策略中，61%的零售商运用库存策略作为...; 关注问题 1  0  0评论

Aisles provide accessibility, not storage, and so this space for aisles is not directly revenue-generating. Consequently we prefer to reduce aisle space to the minimum necessary to provide a dequate accessibility. For this the aisles must be at least wide enough for a forklift to insert or extract a pallet. By storing product in lanes, additional pallet positions ca n share the same aisle space and so amortize that cost. Should lanes be four pallets deep? Six? Ten? There are many issues to consider, but the most important one is effective utilization of...; 关注问题 2  1  0评论

felix 发起了提问 2020-06-24 20:50 仓储与配送科学: 问答仓储与配送科学-6.1.1 Rack or stack?

Pallets that can be stacked high allow many pallet positions per unit of floor space. Conversely, pallets that are unusually heavy or fragile or that have uneven top surfaces cannot be stack ed very high and so render unusable all the space above. This waste may be avoided by installing pallet rack, so that pallets may be stored independently of each other. How much pallet rack should be purchased and what should be stored therein? The value of the rack to the user depends on the sizes and movement patterns of the particular SKUs that visit the warehou...; 关注问题 2  0  0评论

One revenue source of the 3rd party warehouse is to charge rent by the pallet-month. But because the warehouse typically tallies its own expenses by the square-foot or square-meter (for exam ple, rent of the building, climate control, cleaning, and so on), the warehouse naturally wants many pallet-positions per unit area. It can achieve this in two ways: by taking advantage of v ertical space and by using deep lanes. ...; 关注问题 2  1  0评论

When product is stored in convenient locations, then it is easy to retrieve when requested by a customer. But what is meant by “convenience” depends on models of labor and of space. These mo dels are simplest for pallets, because they have some standard dimensions and are, in many cases, handled one at a time. The concept of“convenience” becomes progressively harder to pin down as we discuss smaller units of storage and handling, such as cartons and pieces.Layout of a unit-load areaThe simplest type of warehouse is a unit-load warehouse, which means that only a single, ...; 关注问题 2  0  0评论

When space is expensive economics says to store product high, which is cheaper than expanding the warehouse out. This has led to some pallet storage at dizzying heights. For example, three s tories is not unusual. Automated storage and retrieval devices are generally used for dangerous heights but not always. We heard of an IBM site that relies on intrepid workers on person -aboard trucks that lift them high into the air. They are safely linked to their truck and so cannot fall; but the problem is how to get them down in case of accident. IBM requires that all ...; 关注问题 3  0  0评论

Sortation equipment is an expensive form of automation that is typically integrated with a conveyor system and installed downstream from picking. It is used mostly when picking cartons, beca use they tend to be fairly uniform in dimension and weight. A sortation system enables pick lists to be constructed purely for effificiency. For example, if twenty customers all want SKU A, it might make sense to send one order picker to pick all the requested SKU A in one trip and rely on the sortation system to separate it all out for the customers. &...; 关注问题 2  0  0评论

Main points: • Conveyors change the economics of travel: Storage locations close to the conveyor are, in terms of labor, close to shipping.• Conveyors partition the warehouse into zones. The track res tricts movement of workers and product because it is hard to cross; and so create problems of balancing work among zones. To alleviate this, conveyors are run up high whenever possible.• Iss ues: How many products are conveyable? What is capacity, especially surge capacity, of conveyor?• Guidelines for layout: Store conveyable product far from shipping because it can travel “for...; 关注问题 1  0  0评论

为一级，负责所有的开放业务，后者负责整合所有独立部门中的物流规划业务，从全局上规划全国的仓储配送体系，两个部门分别由唐伟和傅兵负责。很快，2016年的11月，京东物流迈出了关键一步，宣布以品牌化运营的方式对社会正式全面开放，京东物流的品牌开始独立出现；2017年4月，京东物流的开放更进一步，成立子集团独立运营，王振辉任CeO。京东物流CeO王振辉京东物流首席战略官傅兵认为，在京东物流刚开始全面开放的几年里，最难的是近二十万人的认知重建——关键在于从过去只服务商城的运营思维，要转变为从客户角度出发的经营思维。他举例，在过去的运营思维下，京东物流只服务于京东商城，面对的是几十万个供应商，京东物流需要对商品有统一的标准，以此保证效率，如果某个供应商的商品不符合标准，比如商品没有贴条形码会直接不被允许入仓；但现在的经营思维下，一切要以客户需求出发，没有统一的标准，不同的客户需求都是个性化的，这个时候，比如客户入库的商品没有条码，京东物流就需要去帮助客户把条码贴上。傅兵记得，那几年王振辉在各种大会、小会，几乎是在所有会议上不断去强化整体运营转经营的目标，为实现这一目标，京东物流一直在做各种尝试，其中最主要的有两件事：下至一线团队组织调整，京东采取了Big Boss的考核激励机制；上至面向客户把物流能力模块化，推出了包括供应链、快递、快运、大件、冷链、云仓、跨境等物流产品模块，通过不同的物流产...; 关注问题 4  10  0评论

Figure 5.3: Gravity flflow rack for cartons. (Adapted from “Warehouse Modernization and Layout Planning Guide”, Department of the Navy, Naval Supply Systems Command, NAVSUP Publication 529, March 1985, p 8-17.) Flow rack is a special type of shelving with shelves that are tilted, with rollers, to bring cases forward for picking (Figure 5.3). The shelves may be 3–1 0 feet deep (0.91–3.0meters). This means that only one case of a product need be on the pick face, which means that many SKUs can be available in a small area of pick-face. This means highSKU-den...; 关注问题 2  0  0评论

(Adapted from “Warehouse Modernization and Layout Planning Guide”, Department of the Navy, Naval Supply Systems Command,NAVSUP Publication 529, March 1985, p 8–17.)Simple shelving is the most basic storage mode and the least expensive (Figure 5.2).The shelves are shallow: 18 or 24 inches (0.46 or 0.61 meters) are typical, for example,but 36 inch (0.91 met er) deep shelf is sometimes used for larger cartons. Because the shelves are shallow, any signifificant quantity of a SKU must spread out along the pick-face. This reduces SKU-density and therefo...; 关注问题 2  0  0评论

Within the warehouse the largest standardized material-handling unit is generally the pallet, which is just a rigid base on which cartons can be stacked. Most are made of wood, but some are made of d urable plastic. Pallets are available in a range of qualities and prices. In general order of quality and price, they include string pallets, block pallets, and perimeter base pallets. Any pallet expected to be handled by automation will generally have to be of high quality. As supply chains get longer, there is an incentive to use higher quality pallets. ...; 关注问题 2  0  0评论
