A warehouse is a commercial building Buildings come in a wide amount of shapes and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, to land prices, ground conditions, specific uses and aesthetic reasons for storage of goods In macroeconomics and accounting, a good is contrasted with a service. In this sense, a good is defined as a physical product, capable of being delivered to a purchaser and involves the transfer of ownership from seller to customer, say an apple, as opposed to an (intangible) service, say a haircut. A more general term that preserves the. Warehouses are used by manufacturers Manufacturing is the use of machines, tools and labor to make things for use or sale. The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale. Such finished goods may be used for manufacturing, importers The term "import" is derived from the conceptual meaning as to bring in the goods and services into the port of a country. The buyer of such goods and services is referred to an "importer" who is based in the country of import whereas the overseas based seller is referred to as an "exporter". Thus an import is any, exporters The term "export" is derived from the conceptual meaning as to ship the goods and services out of the port of a country. The seller of such goods and services is referred to as an "exporter" who is based in the country of export whereas the overseas based buyer is referred to as an "importer". In International Trade, &, wholesalers Wholesaling, jobbing, or distributing is defined as the sale of goods or merchandise to retailers, to industrial, commercial, institutional, or other professional business users, or to other wholesalers and related subordinated services. In general, it is the sale of goods to anyone other than a standard consumer, transport Transport or transportation is the movement of people and goods from one location to another. Modes of transport include air, rail, road, water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations businesses, customs Customs is an authority or agency in a country responsible for collecting and safeguarding customs duties and for controlling the flow of goods including animals, personal effects and hazardous items in and out of a country. Depending on local legislation and regulations, the import or export of some goods may be restricted or forbidden, and the, etc. They are usually large plain buildings in industrial areas of cities and towns. They usually have loading docks A loading dock is a recessed bay in a building or facility where trucks are loaded and unloaded. They are commonly found on commercial and industrial buildings, and warehouses in particular to load and unload goods from trucks. Sometimes warehouses load and unload goods directly from railways Rail transport is the means of conveyance of passengers and goods by way of wheeled vehicles running on rail tracks. In contrast to road transport, where vehicles merely run on a prepared surface, rail vehicles are also directionally guided by the tracks they run on. Track usually consists of steel rails installed on sleepers/ties and ballast, on, airports An airport is a location where aircraft such as fixed-wing aircraft, helicopters, and blimps takeoff and land. Aircraft may be stored or maintained at an airport. An airport consists of at least one surface such as a runway for a plane to takeoff and land, a helipad, or water for takeoffs and landings, and often includes buildings such as control, or seaports A port is a location on a coast or shore containing one or more harbors where ships can dock and transfer people or cargo to or from land. Port locations are selected to optimize access to land and navigable water, for commercial demand, and for shelter from wind and waves. Ports with deeper water are rarer, but can handle larger, more economical. They often have cranes A crane is a lifting machine, generally equipped with a winder , wire ropes or chains and sheaves, that can be used both to lift and lower materials and to move them horizontally. It uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in the and forklifts A forklift is a powered industrial truck used to lift and transport materials. The modern forklift was developed in the 1920s by various companies including the transmission manufacturing company Clark and the hoist company Yale & Towne Manufacturing. The forklift has since become an indispensable piece of equipment in manufacturing and for moving goods, which are usually placed on ISO The International Organization for Standardization , widely known as ISO (pronounced /ˈaɪsoʊ/ EYE-soe), is an international-standard-setting body composed of representatives from various national standards organizations. Founded on 23 February 1947, the organization promulgates worldwide proprietary industrial and commercial standards. It has standard pallets A pallet (sometimes called a skid) is a flat transport structure that supports goods in a stable fashion while being lifted by a forklift, pallet jack, front loader or other jacking device. A pallet is the structural foundation of a unit load which allows handling and storage efficiencies. Goods or shipping containers are often placed on a pallet loaded into pallet racks Pallet racking, ” is a material handling storage aid system designed to store materials on pallets . Although there are many varieties of pallet rack, all types allow for the storage of palletized materials in horizontal rows with multiple levels. All types of pallet rack create some level of increase storage density with the least dense being.

Nature of goods stored
Stored goods can include any raw materials, components, or finished goods associated with agriculture, manufacturing, or commerce.
Types of warehouse storage systems
19th century warehouses in Gloucester Gloucester (pronounced /ˈɡlɒstər/ GLOS-tər) is a city, district and county town of Gloucestershire in the South West region of England. Gloucester lies close to the Welsh border, and on the River Severn, approximately 32 miles (51 km) north-east of Bristol, and 45 miles (72 km) south-southwest of Birmingham docks in the United Kingdom, originally used to store imported corn So-called Sust, a Middle Ages The Middle Ages is a period of European history from the 5th century to the 15th century. The period followed the fall of the Western Roman Empire in 476, and preceded the Early Modern Era. It is the middle period in a three-period division of history: Classical, Medieval, and Modern. The term "Middle Ages" (medium aevum) was coined in type of warehouse, in Horgen Horgen is a village in the district of Horgen in the canton of Zürich in Switzerland, Switzerland Switzerland , officially the Swiss Confederation (Confœderatio Helvetica in Latin, hence its ISO country codes CH and CHE), is a federal republic consisting of 26 cantons, with Bern as the seat of the federal authorities. The country is situated in Western Europe[note 4] where it is bordered by Germany to the north, France to the west, Italy toSome of the most common warehouse storage systems are:
- Pallet rack Pallet racking, ” is a material handling storage aid system designed to store materials on pallets . Although there are many varieties of pallet rack, all types allow for the storage of palletized materials in horizontal rows with multiple levels. All types of pallet rack create some level of increase storage density with the least dense being including selective, drive-in, drive-thru, double-deep, pushback, and gravity flow
- Mezzanine In architecture, a mezzanine or entresol is an intermediate floor between main floors of a building, and therefore typically not counted among the overall floors of a building. Often, a mezzanine is low-ceilinged and projects in the form of a balcony. The term is also used for the lowest balcony in a theatre, or for the first few rows of seats in including structural, roll formed, rack supported, and shelf supported
- Cantilever A cantilever is a beam supported on only one end. The beam carries the load to the support where it is resisted by moment and shear stress. Cantilever construction allows for overhanging structures without external bracing. Cantilevers can also be constructed with trusses or slabs Rack including structural and roll formed
- Industrial Shelving including metal, steel, wire, and catwalk
- Automated Storage and Retrieval System ASRS are categorized into three main types: single masted, double masted and man-aboard. Most are supported on a track and ceiling guided at the top by guide rails or channels to ensure accurate vertical alignment, although some are suspended from the ceiling. The 'shuttles' that make up the system travel between fixed storage shelves to deposit (ASRS) including vertical carousels, vertical lift modules, horizontal carousels, robotics, mini loads, and compact 3D
Processes and IT
Major warehousing processes include:
- Receiving
- Put away
- Order preparation / picking
- Shipping
- Inventory management (cycle counting, addressing...)
Warehouses frequently provide services, such as:
- Co-packing
- Kitting
- Repair
A piece pick, also known as broken case pick, split-case pick, each pick, over-pack or pick/pack, is a type of order selection process where product is picked and handled in individual units and placed in an outer carton, tote or other container before shipping. Catalog companies and internet retailers are examples of predominantly piece-pick operations. Their customers rarely order in pallet or case quantities; instead, they typically order just one or two pieces of one or two items.
Material direction and tracking in a warehouse can be coordinated by a Warehouse Management System A warehouse management system, or WMS, is a key part of the supply chain and primarily aims to control the movement and storage of materials within a warehouse and process the associated transactions, including shipping, receiving, putaway and picking. The systems also direct and optimize stock putaway based on real-time information about the (WMS), a database A database consists of an organized collection of data for one or more uses, typically in digital form. One way of classifying databases involves the type of their contents, for example: bibliographic, document-text, statistical. Digital databases are managed using database management systems, which store database contents, allowing data creation driven computer program. Logistics Logistics is the management of the flow of goods, information and other resources in a repair cycle between the point of origin and the point of consumption in order to meet the requirements of customers. Logistics involves the integration of information, transportation, inventory, warehousing, material handling, and packaging, and occasionally personnel use the WMS to improve warehouse efficiency by directing putaways and to maintain accurate inventory Inventory is a list for goods and materials, or those goods and materials themselves, held available in stock by a business. It is also used for a list of the contents of a household and for a list for testamentary purposes of the possessions of someone who has died. In accounting, inventory is considered an asset by recording warehouse transactions.
Automation and optimization
Automatic storage warehouse for small partsSome warehouses are completely automated Automation is the use of control systems and information technologies reducing the need for human intervention. In the scope of industrialization, automation is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the muscular requirements of work, automation greatly reduces the need for, and require no workers inside. Pallets and product move on a system of automated conveyors A conveyor system is a common piece of mechanical handling equipment that moves materials from one location to another. Conveyors are especially useful in applications involving the transportation of heavy or bulky materials. Conveyor systems allow quick and efficient transportation for a wide variety of materials, which make them very popular in, cranes A crane is a lifting machine, generally equipped with a winder , wire ropes or chains and sheaves, that can be used both to lift and lower materials and to move them horizontally. It uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in the and automated storage and retrieval systems ASRS are categorized into three main types: single masted, double masted and man-aboard. Most are supported on a track and ceiling guided at the top by guide rails or channels to ensure accurate vertical alignment, although some are suspended from the ceiling. The 'shuttles' that make up the system travel between fixed storage shelves to deposit coordinated by programmable logic controllers A programmable logic controller or programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or lighting fixtures. PLCs are used in many industries and machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and computers A computer is a programmable machine that receives input, stores and manipulates data//information, and provides output in a useful format running logistics automation Logistics automation is the application of computer software and/or automated machinery to improve the efficiency of logistics operations. Typically this refers to operations within a warehouse or distribution center, with broader tasks undertaken by supply chain management systems and enterprise resource planning systems software. These systems are often installed in refrigerated Refrigeration is the process of removing heat from an enclosed space, or from a substance, and moving it to a place where it is unobjectionable. The primary purpose of refrigeration is lowering the temperature of the enclosed space or substance and then maintaining that lower temperature. The term cooling refers generally to any natural or warehouses where temperatures are kept very cold to keep product from spoiling, and also where land is expensive, as automated storage systems can use vertical space efficiently. These high-bay storage areas are often more than 10 meters (33 feet) high, with some over 20 meters (65 feet) high.
For a warehouse to function efficiently, the facility must be properly slotted. Slotting addresses which storage medium a product is picked from (pallet rack Pallet racking, ” is a material handling storage aid system designed to store materials on pallets . Although there are many varieties of pallet rack, all types allow for the storage of palletized materials in horizontal rows with multiple levels. All types of pallet rack create some level of increase storage density with the least dense being or carton flow Put simply, the main advantage of carton flow rack over static rack or shelving systems is that merchandise remains better organized and easier to find/pick. With carton flow rack, the product is automatically rotated on a first in first out basis. Merchandise is stocked in the rear of the carton flow rack and moves toward the picking station in), and how they are picked (pick-to-light, pick-to-voice Voice Directed Warehousing is the implementation of speech recognition in Warehouse Management Systems. VDW was originally limited to picking, whereas now all warehouse functions (picking, receiving/put-away, replenishment, shipping) can be coordinated by voice systems, or pick-to-paper). With a proper slotting plan, a warehouse can improve its inventory rotation requirements—such as first in, first out (FIFO) and last in, first out (LIFO) FIFO and LIFO accounting Methods are means of managing inventory and financial matters involving the money a company tied up within inventory of produced goods, raw materials, parts, components, or feed stocks. FIFO stands for first-in, first-out, meaning that the oldest inventory items are recorded as sold first. LIFO stands for last-in, first-—control labor costs and increase productivity.[1]
Modern trends
Aisle with pallets on storage racksTraditional warehousing has declined since the last decades of the 20th century, with the gradual introduction of Just In Time Just-in-time is an inventory strategy that strives to improve a business's return on investment by reducing in-process inventory and associated carrying costs. To meet JIT objectives, the process relies on signals or Kanban (看板, Kanban?) between different points in the process, which tell production when to make the next part. Kanban are (JIT) techniques. The JIT system promotes product delivery directly from suppliers to consumer without the use of warehouses. However, with the gradual implementation of offshore outsourcing Offshore outsourcing is the practice of hiring an external organization to perform some business functions in a country other than the one where the products or services are actually developed or manufactured. It can be contrasted with offshoring, in which the functions are performed in a foreign country by a foreign subsidiary. Opponents point and offshoring Offshoring describes the relocation by a company of a business process from one country to another—typically an operational process, such as manufacturing, or supporting processes, such as accounting. Even state governments employ offshoring in about the same time period, the distance between the manufacturer and the retailer (or the parts manufacturer and the industrial plant) grew considerably in many domains, necessitating at least one warehouse per country or per region in any typical supply chain A supply chain is a system of organizations, people, technology, activities, information and resources involved in moving a product or service from supplier to customer. Supply chain activities transform natural resources, raw materials and components into a finished product that is delivered to the end customer. In sophisticated supply chain for a given range of products.
Recent retailing trends have led to the development of warehouse-style retail stores. These high-ceiling buildings display retail goods on tall, heavy duty industrial racks rather than conventional retail shelving. Typically, items ready for sale are on the bottom of the racks, and crated or palletized inventory is in the upper rack. Essentially, the same building serves as both warehouse and retail store.
Large exporters/manufacturers use warehouses as distribution points for developing retail outlets in a particular region or country. This concept reduces end cost to the consumer and enhances the production sale ratio.

19th century warehouse in Frankfort Frankfort is a city in the Commonwealth of Kentucky that serves as the state capital and the county seat of Franklin County. The population was 27,741 at the 2000 census; by population, it is the 5th smallest state capital in the United States. Frankfort is the principal city of the Frankfort, Kentucky Micropolitan Statistical Area, which includes, Kentucky Kentucky is known as the "Bluegrass State", a nickname based on the fact that native bluegrass is present in many of the pastures throughout the state, based on the fertile soil. It made possible the breeding of high-quality livestock, especially thoroughbred racing horses. It is a land with diverse environments and abundant resources,, United States ^ b. English is the de facto language of American government and the sole language spoken at home by 80% of Americans age five and older. Spanish is the second most commonly spoken language used to age bourbon whiskey Bourbon is an American whiskey, a type of distilled spirit, made primarily from corn and named for Bourbon County, Kentucky. It has been produced since the 18th century. While it may be made anywhere in the United States, it is strongly associated with the Commonwealth of Kentucky casks A barrel or cask is a hollow cylindrical container, traditionally made of vertical wooden staves and bound by wooden or metal hoops. Traditionally, the barrel was a standard size of measure referring to a set capacity or weight of a given commodity. For example, a beer barrel was originally a 36 gallon capacity while an ale barrel was a 32 gallon, seen closely through the warehouse windowsThe internet has had an influence on warehouses. Internet-based stores do not require physical retail space, but still require warehouses to store goods. This kind of warehouse fills many small orders directly from end customers rather than fewer orders of many items from stores.
Having a large and complex supply chain containing many warehouse can be costly. It may be beneficial for a company to have one large warehouse per continent, typically located centrally to transportation. At these continental hubs, goods may be customized for different countries. For example, goods get a price ticket in the language of the destination country. Small, in-warehouse adjustments to goods are called value added services.
