Logistics is generally the detailed organization and implementation of a complex operation. In a general business sense, logistics manages the flow of goods between the point of origin and the point of consumption to meet the requirements of customers or corporations. The resources managed in logistics may include tangible goods such as materials, equipment, and supplies, as well as food and other consumable items. In

that plans, implements, and controls the efficient, effective forward, and reverse flow and storage of goods, services, and related information between the point of origin and point of consumption to meet customers' requirements. The complexity of logistics can be modeled, analyzed, visualized, and optimized by dedicated simulation software. The minimization of the use of resources is a common motivation in all logistics fields. A professional working in the field of logistics management is called a logistician.

The term is credited to Jomini, and the term and its etymology criticized by Georges de Chambray in 1832, writing: ''Logistic'': This word appears to me to be completely new, as I have not yet seen it anywhere in military literature. … he appears to derive it from the word ''lodgings'' 'logis'' a peculiar etymology … Chambray also notes that the term french: label=none, logistique was present in the ' as a synonym for

'' defines logistics as "the detailed coordination of a complex operation involving many people, facilities, or supplies", and the Oxford Dictionary on-line defines it as "the detailed organization and implementation of a complex operation". As such, logistics is commonly seen as a branch of engineering that creates "people systems" rather than "machine systems". According to the Council of Supply Chain Management Professionals (previously the Council of Logistics Management), logistics is the process of planning, implementing and controlling procedures for the efficient and effective transportation and storage of goods including services and related information from the point of origin to the point of consumption for the purpose of conforming to customer requirements and includes inbound, outbound, internal and external movements.CSCMP glossary Academics and practitioners traditionally refer to the terms operations or production management when referring to physical transformations taking place in a single business location (factory, restaurant or even bank clerking) and reserve the term logistics for activities related to distribution, that is, moving products on the territory. Managing a distribution center is seen, therefore, as pertaining to the realm of logistics since, while in theory, the products made by a factory are ready for consumption they still need to be moved along the distribution network according to some logic, and the distribution center aggregates and processes orders coming from different areas of the territory. That being said, from a modeling perspective, there are similarities between operations management and logistics, and companies sometimes use hybrid professionals, with for example a "Director of Operations" or a "Logistics Officer" working on similar problems. Furthermore, the term "

Logistics activities and fields

Inbound logistics is one of the primary processes of logistics concentrating on purchasing and arranging the inbound movement of materials, parts, or unfinished inventory from suppliers to manufacturing or assembly plants, warehouses, or retail stores. Outbound logistics is the process related to the storage and movement of the final product and the related information flows from the end of the production line to the end user. Given the services performed by logisticians, the main fields of logistics can be broken down as follows: * Procurement logistics * Distribution logistics * After-sales logistics * Disposal logistics *
Reverse logistics Reverse logistics encompasses all operations related to the upstream movement of products and materials. It is "the process of moving goods from their typical final destination for the purpose of capturing value, or proper disposal. Remanufacturin ...

The targets in procurement logistics might be contradictory: maximizing efficiency by concentrating on core competences, outsourcing while maintaining the autonomy of the company, or minimizing procurement costs while maximizing security within the supply process. Advance Logistics consists of the activities required to set up or establish a plan for logistics activities to occur. Global Logistics is technically the process of managing the "flow" of goods through what is called a supply chain, from its place of production to other parts of the world. This often requires an intermodal transport system, transport via ocean, air, rail, and truck. The effectiveness of global logistics is measured in the

. Distribution logistics has, as main tasks, the delivery of the finished products to the customer. It consists of order processing, warehousing, and transportation. Distribution logistics is necessary because the time, place, and quantity of production differ with the time, place, and quantity of consumption. Disposal logistics has as its main function to reduce logistics cost(s) and enhance service(s) related to the disposal of waste produced during the operation of a business. Reverse logistics denotes all those operations related to the reuse of products and materials. The reverse logistics process includes the management and the sale of surpluses, as well as products being returned to vendors from buyers. Reverse logistics stands for all operations related to the reuse of products and materials. It is "the process of planning, implementing, and controlling the efficient, cost-effective flow of raw materials, in-process inventory, finished goods and related information from the point of consumption to the point of origin for the purpose of recapturing value or proper disposal. More precisely, reverse logistics is the process of moving goods from their typical final destination for the purpose of capturing value, or proper disposal. The opposite of reverse logistics is forward logistics." Green Logistics describes all attempts to measure and minimize the ecological impact of logistics activities. This includes all activities of the forward and reverse flows. This can be achieved through

Emergency logistics (or Humanitarian Logistics) is a term used by the logistics, supply chain, and manufacturing industries to denote specific time-critical modes of transport used to move goods or rapidly in the event of an emergency.Cozzolino Alessandra, Humanitarian Logistics and Supply Chain Management, In Humanitarian Logistics, Springer Berlin Heidelberg 2012 The reason for enlisting emergency logistics services could be a production delay or anticipated production delay, or an urgent need for specialized equipment to prevent events such as aircraft being grounded (also known as "

"—AOG), ships being delayed, or telecommunications failure. Humanitarian logistics involves governments, the military, aid agencies, donors, non-governmental organizations and emergency logistics services are typically sourced from a specialist provider. The term production logistics describes logistic processes within a value-adding system (ex: factory or a mine). Production logistics aims to ensure that each machine and workstation receives the right product in the right quantity and quality at the right time. The concern is with production, testing, transportation, storage, and supply. Production logistics can operate in existing as well as new plants: since manufacturing in an existing plant is a constantly changing process, machines are exchanged and new ones added, which gives the opportunity to improve the production logistics system accordingly. Production logistics provides the means to achieve customer response and capital efficiency. Production logistics becomes more important with decreasing batch sizes. In many industries (e.g.
mobile phones A mobile phone, cellular phone, cell phone, cellphone, handphone, hand phone or pocket phone, sometimes shortened to simply mobile, cell, or just phone, is a portable telephone that can make and receive calls over a radio frequency link while ...

' categorical supply classification was developed in such a way that categories of supply with similar consumption variables are grouped together for planning purposes. For instance, peacetime consumption of ammunition and fuel will be considerably lower than wartime consumption of these items, whereas other classes of supply such as subsistence and clothing have a relatively consistent consumption rate regardless of war or peace. Some classes of supply have a linear demand relationship: as more troops are added, more supply items are needed; or as more equipment is used, more fuel and ammunition are consumed. Other classes of supply must consider a third variable besides usage and quantity: time. As equipment ages, more and more repair parts are needed over time, even when usage and quantity stay consistent. By recording and analyzing these trends over time and applying them to future scenarios, the US Armed Forces can accurately supply troops with the items necessary at the precise moment they are needed. History has shown that good logistical planning creates a lean and efficient fighting force. The lack thereof can lead to a clunky, slow, and ill-equipped force with too much or too little supply.

The term "business logistics" has evolved since the 1960s due to the increasing complexity of supplying businesses with materials and shipping out products in an increasingly globalized supply chain, leading to a call for professionals called "supply chain logisticians".

Configuration and management

Similarly to production systems, logistic systems need to be properly configured and managed. Actually a number of methodologies have been directly borrowed from operations management such as using Economic Order Quantity models for managing inventory in the nodes of the network.

are very rarely owned by a single enterprise. Distribution networks can be characterized by numbers of levels, namely the number of intermediary nodes between supplier and consumer: * Direct store delivery, i.e. zero levels * One level network: central warehouse * Two level network: central and peripheral warehouses This distinction is more useful for modeling purposes, but it relates also to a tactical decision regarding safety stocks: considering a two-level network, if safety inventory is kept only in peripheral warehouses then it is called a dependent system (from suppliers), if safety inventory is distributed among central and peripheral warehouses it is called an independent system (from suppliers). Transportation from producer to the second level is called primary transportation, from the second level to a consumer is called secondary transportation. Although configuring a distribution network from zero is possible, logisticians usually have to deal with restructuring existing networks due to presence of an array of factors: changing demand, product or process innovation, opportunities for outsourcing, change of government policy toward

s and expiration dates. At the warehouse level, the logistician must decide how to distribute merchandise over the racks. Three basic situations are traditionally considered: shared storage, dedicated storage (rack space reserved for specific merchandise) and class-based storage (class meaning merchandise organized in different areas according to their access index). Picking efficiency varies greatly depending on the situation. For a man to goods situation, a distinction is carried out between high-level picking (vertical component significant) and low-level picking (vertical component insignificant). A number of tactical decisions regarding picking must be made: * Routing path: standard alternatives include transversal routing, return routing, midpoint routing, and largest gap return routing * Replenishment method: standard alternatives include equal space supply for each product class and equal time supply for each product class. * Picking logic: order picking vs batch picking At the level of the distribution network, tactical decisions involve mainly

Warehouse management system and control

Although there is some overlap in functionality, warehouse management systems (WMS) can differ significantly from

s (WCS). Simply put, a WMS plans a weekly activity forecast based on such factors as statistics and trends, whereas a WCS acts like a floor supervisor, working in real-time to get the job done by the most effective means. For instance, a WMS can tell the system that it is going to need five of stock-keeping unit (SKU) A and five of SKU B hours in advance, but by the time it acts, other considerations may have come into play or there could be a logjam on a conveyor. A WCS can prevent that problem by working in real-time and adapting to the situation by making a last-minute decision based on current activity and operational status. Working synergistically, WMS and WCS can resolve these issues and maximize

Logistics outsourcing

Logistics outsourcing involves a relationship between a company and an LSP (logistic service provider), which, compared with basic logistics services, has more customized offerings, encompasses a broad number of service activities, is characterized by a long-term orientation, and thus has a strategic nature. Outsourcing does not have to be complete externalization to an LSP, but can also be partial: * A single contract for supplying a specific service on occasion * Creation of a
spin-off Spin-off may refer to: *Spin-off (media), a media work derived from an existing work *Corporate spin-off, a type of corporate action that forms a new company or entity * Government spin-off, civilian goods which are the result of military or gov ...
* Creation of a joint venture Third-party logistics (3PL) involves using external organizations to execute logistics activities that have traditionally been performed within an organization itself. According to this definition, third-party logistics includes any form of outsourcing of logistics activities previously performed in house. For example, if a company with its own warehousing facilities decides to employ external transportation, this would be an example of third-party logistics. Logistics is an emerging business area in many countries. External 3PL providers have evolved from merely providing logistics capabilities to becoming real orchestrators of supply chains that create and sustain a competitive advantage, thus bringing about new levels of logistics outsourcing. The concept of a fourth-party logistics (4PL) provider was first defined by Andersen Consulting (now

) as an integrator that assembles the resources, planning capabilities, and technology of its own organization and other organizations to design, build, and run comprehensive supply chain solutions. Whereas a third-party logistics (3PL) service provider targets a single function, a 4PL targets management of the entire process. Some have described a 4PL as a general contractor that manages other 3PLs, truckers, forwarders, custom house agents, and others, essentially taking responsibility of a complete process for the customer.


Horizontal alliances between logistics service providers

Horizontal business alliances often occur between logistics service providers, i.e., the cooperation between two or more logistics companies that are potentially competing. In a horizontal alliance, these partners can benefit twofold. On one hand, they can "access tangible resources which are directly exploitable". In this example extending common transportation networks, their warehouse infrastructure and the ability to provide more complex service packages can be achieved by combining resources. On the other hand, partners can "access intangible resources, which are not directly exploitable". This typically includes know-how and information and, in turn, innovation.

Information in traditional bar codes is stored as a sequence of black and white bars varying in width, which when read by laser is translated into a digital sequence, which according to fixed rules can be converted into a decimal number or other data. Sometimes information in a bar code can be transmitted through radio frequency, more typically radio transmission is used in RFID tags. An RFID tag is a card containing a memory chip and an antenna that transmits signals to a reader. RFID may be found on merchandise, animals, vehicles, and people as well.


Logistics: profession and organizations

A logistician is a professional logistics practitioner. Professional logisticians are often certified by professional associations. One can either work in a pure logistics company, such as a shipping line, airport, or freight forwarder, or within the logistics department of a company. However, as mentioned above, logistics is a broad field, encompassing procurement, production, distribution, and disposal activities. Hence, career perspectives are broad as well. A new trend in the industry is the 4PL, or fourth-party logistics, firms, consulting companies offering logistics services. Some universities and academic institutions train students as logisticians, offering undergraduate and postgraduate programs. A university with a primary focus on logistics is Kühne Logistics University in Hamburg, Germany. It is non-profit and supported by Kühne-Foundation of the logistics entrepreneur Klaus Michael Kühne.
