A review of the organisation was to take place and the MNAO was to become a lodger unit at RNAS Lossiemouth , Moray . In particular MONAB X and MATMU 1 were to be housed at RNAS Lossiemouth while MR 4 was to be installed at Lossiemouth's satellite airfield RNAS Milltown . Lossiemouth
1998-547: 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,
2109-494: A significant need for logistics solutions and so have developed advanced implementations. Integrated logistics support (ILS) is a discipline used in military industries to ensure an easily supportable system with a robust customer service (logistic) concept at the lowest cost and in line with (often high) reliability, availability, maintainability, and other requirements, as defined for the project. In military logistics , Logistics Officers manage how and when to move resources to

A maintenance release
2331-503: A single customer's demand to be fulfilled efficiently. Track and tracing , which is an essential part of production logistics due to product safety and reliability issues, is also gaining importance, especially in the automotive and medical industries. Construction logistics has been employed by civilizations for thousands of years as the various human civilizations tried to build the best possible works of construction for living and protection. Now, construction logistics has emerged as

#17328631361532442-484: A specialist provider. The term production logistics describes logistic processes within a value-adding system (ex, a factory or a mine). Production logistics aims to ensure that each machine and workstation receives the right product in the correct 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
2553-736: A stockpile of finished goods beforehand can reduce the frequency of transportation to and from the customers and cope with the randomness of customer demands. However, maintaining an inventory requires capital investment in finished goods and maintaining a warehouse. Storage and order picking occupy most of the warehouse maintenance cost. Freight transportation forms a vital part of logistics and allows access to broad markets as goods can be transported to hundreds or thousands of kilometers away. Freight transportation accounts for two-thirds of logistical costs and significantly impacts customer service. Transportation policies and warehouse management are closely intertwined. The rise of commercial transactions through
2664-474: A typical MONAB were adjusted as necessary and it is entirely feasible that no two MONABs had the same complement. Additional officers and ratings were added post formation and despatch as each unit needed to be modified to meet a specific role. Arguably, MONAB VII was likely the nearest to something of a standard complement. MONABs were required to accommodate and feed 950 personnel from disembarked squadrons. Any MONAB that held large numbers of reserve aircraft had
2775-421: A vital part of construction. In the past few years, construction logistics has emerged as a different field of knowledge and study within supply chain management and logistics. The Seven R's is a popular concept used to enforce best practices in logistics management which consists of the following: In military science, maintaining one's supply lines while disrupting those of the enemy is a crucial—some would say
2886-710: A warehouse. A distribution network would require several intermediaries to bring consumer or industrial goods from manufacturers to a user. Intermediaries would markup the costs of the products during distribution, but benefit users by providing lower transportation costs than the manufacturers. The number of intermediaries required for the distribution network depends upon the types of goods being distributed. For example, consumer goods such as cosmetics and handicrafts may not require any intermediaries as they can be sold door-to-door or can be obtained from local flea markets. For industrial goods such as raw materials and equipment, intermediaries are not needed because manufacturers can sell
2997-685: Is a component that holds the supply chain together. The resources managed in logistics may include tangible goods such as materials, equipment, and supplies, as well as food and other consumable items. In military logistics , it is concerned with maintaining army supply lines with food, armaments, ammunition, and spare parts apart from the transportation of troops themselves. Meanwhile, civil logistics deals with acquiring, moving, and storing raw materials, semi-finished goods, and finished goods. For organisations that provide garbage collection, mail deliveries, public utilities, and after-sales services, logistical problems must be addressed. Logistics deals with
3108-416: Is a constantly changing process, machines are exchanged and new ones added, which allows for improving 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 ), the short-term goal is a batch size of one, allowing even
3219-516: Is governed by EASA Part-66. A person directly licensed to certify flightworthiness is a holder of a Part-66 AML (Aircraft Maintenance License). In many other countries, including Australia, Bangla Desh, Canada, India, New Zealand and South Africa, a person directly granted the privilege of certification is a qualified AME ( Aircraft Maintenance Engineer ) or Licensed AME, also written as LAME or L-AME. (Unlicensed mechanics or tradespersons are sometimes informally referred to as "Unlicensed AMEs" ) In
3330-540: Is measured in the Logistics Performance Index . Distribution logistics has, as its main task, the delivery of the finished products to the customer. It consists of order processing, warehousing, and transportation. Distribution logistics is necessary because production time, place, and quantity differ with the time, place, and quantity of consumption. Disposal logistics has the main function of reducing logistics cost(s) and enhancing service(s) related to

Some sources give this instead as the source of logistics , either ignorant of Jomini's statement that it was derived from logis , or dubious and instead believing it was in fact of Greek origin, or influenced by the existing term of Greek origin. Jomini originally defined logistics as: ... l'art de bien ordonner les marches d'une armée, de bien combiner l'ordre des troupes dans les colonnes, les tems [temps] de leur départ, leur itinéraire, les moyens de communications nécessaires pour assurer leur arrivée à point nommé ... ...

7659-448: The end of World War II . There were a number of units within and each unit was self-contained and designed to service and repair aircraft and engines . Each were initially assembled at the MNAO headquarters at HMS Flycatcher , which first commissioned at RNAS Ludham , Norfolk , then later at RNAS Middle Wallop , Hampshire , both in the UK , and then were forward deployed. When
7770-495: The enemy. These were to supply personnel and material, typical of naval aviation , to facilitate naval aircraft to utilise airfields controlled by the Royal Air Force or any other Service . The TAMY was much less mobile than a MONAB and much more complex. These were not intended for the forward areas and were expected to be situated close to the main fleet, and their personnel needed to be highly skilled. They were equipped with
7881-507: The event of an emergency. 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 " aircraft on ground "—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
7992-458: The following day. The airfield returned to the RAAF and HMS Nabstock decommissioned in June 1946. MONAB VII assembled at RNAS Middle Wallop (HMS Flycatcher ) from mid-March 1945. It was conceived as a Receipt and Despatch unit. It sailed for Australia in June and arrived in Sydney on 28 July. Travelling onwards, it arrived at the former USN Seabee camp at Meeandah, near Brisbane, on 9 August and shared
8103-493: The forward and reverse flows. This can be achieved through intermodal freight transport , path optimization, vehicle saturation, and city logistics . RAM logistics (see also Logistic engineering ) combines both business logistics and military logistics since it concerns highly complicated technological systems for which reliability , availability and maintainability are essential, e.g., weapon system and military supercomputers. Asset control logistics : companies in
8214-474: The hour", provides budget predictability, avoids installing a loan unit during repairs when an aircraft part fails and enrolled aircraft may have a better value and liquidity. This concept of unscheduled maintenance was initially introduced for aircraft engines to mitigate engine failures . The term was coined by Bristol Siddeley in 1962 to support Vipers of the British Aerospace 125 business jets for
8325-739: 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. 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 consists of market research , requirements planning, make-or-buy decisions, supplier management, ordering, and order control. The targets in procurement logistics might be contradictory: maximizing efficiency by concentrating on core competencies, outsourcing while maintaining
8436-444: The internet gives rise to the need for "e-logistics". Compared to traditional logistics, e-logistics handles parcels valued at less than a hundred US dollars to customers scattered at various destinations worldwide. In e-logistics, customers' demands come in waves when compared to traditional logistics, where the demand is consistent. Inbound logistics is one of the primary logistics processes concentrating on purchasing and arranging
8547-529: The latter included mobile repair, supporting 100 aircraft (the equivalent of a TAB). A third unit was created, a Transportable Aircraft Maintenance Yard (TAMY), to provide mobile aircraft repair facilities. The initial idea of the MONAB was "the rapid provision of facilities at airfields and airstrips for the training and maintenance of naval air squadrons disembarked from carriers operating in advance of existing bases". These were not envisaged as an active shore base for naval aircraft to operate from against
8658-706: The market, increasing concerns about intellectual property sharing. Shared data-supported predictive maintenance can reduce operational disruptions. Among other factors, prognostics helped Delta Air Lines reduce maintenance cancellations by 98% from 5,600 in 2010 to 78 in 2017. Insourced maintenance can be inefficient for small airlines with a fleet below 50–60 aircraft. They have to either outsource it or sell its MRO services to other carriers for better resource utilization. For example, Spain's Air Nostrum operates 45 Bombardier CRJs and ATR 72s and its 300-person maintenance department provides line, base maintenance and limited component repair for other airlines 20% of
8769-579: The mobilisation. Vehicles for functions and roles such as: containerised workshops and offices, air traffic control and Very high frequency (VHF) and Direction finding (DF) vans, meteorological van for weather forecasting, photographic tender, bakery , electrical generating, crashtenders , ambulances , and more. The basic MONAB structure comprised a fixed set of six common elements: command, administration, repair & air maintenance, operations & training, airfield defence, and construction. The repair and maintenance components were then relevant to
8880-513: The most crucial—element of military strategy , since an armed force without resources and transportation is defenseless. The historical leaders Hannibal , Alexander the Great , and the Duke of Wellington are considered to have been logistical geniuses: Alexander's expedition benefited considerably from his meticulous attention to the provisioning of his army, Hannibal is credited to have "taught logistics" to
8991-565: The movements of materials or products from one facility to another; it does not include material flow within the production or assembly plants, such as production planning or single-machine scheduling . Logistics occupies a significant amount of the operational cost of an organisation or country. Logistical costs of organizations in the United States incurred about 11% of the United States national gross domestic product (GDP) as of 1997. In
9102-400: The multi-year stream of spares and services, resembling the razor and blades model . Engines installed on a new aircraft are discounted by at least 40% while spare engine values closely follow list prices. Accounting for 80% of a shop visit cost, LLP prices escalate to recoup the original discount, until engine availability increase with aircraft teardowns . Between 2001 and 2018 for
9213-513: The naval threat in the Atlantic was clearly vanishing, with the decline of Nazi Germany , proposals were made to involve the Royal Navy in the Pacific War . The United States Navy 's Commander-in-Chief , Admiral Ernest King , did not welcome this, however. A well-known anglophobe , King preferred to exclude the British and, in addition, he laid down operating requirements that could not be met at
9324-702: The officers of the general staff were named: marshall of lodgings, major-general of lodgings; from there came the term of logistics [ logistique ], which we employ to designate those who are in charge of the functioning of an army. The term is credited to Jomini, and the term and its etymology criticized by Georges de Chambray in 1832, writing: Logistique : Ce mot me paraît être tout-à-fait nouveau, car je ne l'avais encore vu nulle part dans la littérature militaire. … il paraît le faire dériver du mot logis , étymologie singulière … 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
9435-426: The organizing and planning of these activities. Logisticians combine professional knowledge of each of these functions to coordinate resources in an organization. There are two fundamentally different forms of logistics: one optimizes a steady flow of material through a network of transport links and storage nodes, while the other coordinates a sequence of resources to carry out some project , such as restructuring
9546-585: The places they are needed. Supply chain management in military logistics often deals with a number of variables in predicting cost, deterioration, consumption , and future demand. The United States Armed Forces ' 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
9657-409: The point of consumption to the point of origin to recapture value or proper disposal." More precisely, reverse logistics moves goods from their typical final destination to capture 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, including all activities of
9768-429: 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
9879-476: The retail channels, both organized retailers and suppliers, often deploy assets required for the display, preservation, and promotion of their products. Some examples are refrigerators, stands, display monitors, seasonal equipment, poster stands & frames. 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 rapidly in
9990-473: The right time at the right place for the right price in the right condition to the right customer". Business logistics incorporates all industry sectors and aims to manage the fruition of project life cycles , supply chains , and resultant efficiencies. 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

Assembled at RNAS Ludlam from mid-October 1944, commissioned as HMS Nabthorpe on 4 December, sailed for Australia and reached Sydney on 27 January 1945. It commissioned at RAAF Station Schofields on 18 February. A Crew Pool and Refresher Flying Squadron , a Supermarine Seafire Operational Training Unit and an Instrument Flying Training Squadron were based at HMS Nabthorpe . Between March and September
10323-415: The terms French : maréchal des logis , lit. 'marshall of lodgings' and French : major-général des logis , lit. 'major-general of lodging': Autrefois les officiers de l’état-major se nommaient: maréchal des logis, major-général des logis; de là est venu le terme de logistique, qu’on emploie pour désigner ce qui se rapporte aux marches d’une armée. Formerly
10434-408: 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,
10545-404: The time the fleet returned to Ceylon but at that point they were then no longer required. The Director Naval Air Division (DNAD) drafted requirements for mobile bases in October 1942 and following a meeting in November the concept of a mobile naval airfield was created. In September 1943, Colonel Fuller, RM , was appointed as Senior Officer Mobile Naval Airfields Organisation (SOMNAO) and this
10656-476: The time. Airframe heavy maintenance is worth $ 6 billion in 2019: $ 2.9 billion for C checks and $ 3.1 billion for D checks , Aviation Week & Space Technology forecasts a growth to $ 7.5 billion in 2028 — $ 3.1 billion C and $ 4.2 billion D — for $ 70 billion over 10 years, 10% of the overall market compared to 40% for the engines. The commercial aviation engine MRO market is anticipated by Aviation Week & Space Technology to be $ 25.9 billion in 2018,
10767-676: The time. One of these was that the Royal Navy should be self-sustaining and independent of United States Navy (USN) logistical resources for extended periods of active service. King was effectively overruled, and the Royal Navy began establishing an adequate logistical infrastructure which included MONABs During the Second World War , to meet the Royal Navy Eastern Fleet 's requirements, to provide serviceable aircraft for aircraft carriers , along with trained aircrew , airbases were constructed in Africa. They were just about completed by
10878-519: The units role: Where specific situations arose, some additional non-technical components could be attached to a MONAB to meet an exact need. For these units it is unknown what size the personnel levels were: With the exception of MONAB II and TAMY I, all mobile airfield units were formed with one Mobile Maintenance element and two Maintenance Servicing elements. Each Mobile Repair element and Maintenance, Storage & Reserve element were attached to each unit where needed. The number of personnel for
10989-473: The word lodgings [ logis ], a peculiar etymology … Chambray also notes that the term logistique was present in the Dictionnaire de l'Académie française as a synonym for algebra . The French word: logistique is a homonym of the existing mathematical term, from Ancient Greek : λογῐστῐκός , romanized : logistikós , a traditional division of Greek mathematics ; the mathematical term
11100-411: Was a time-consuming activity that could take up to 70% of the order-cycle time. However, with new technologies such as bar code scanning, computers, and network connection, customer orders can quickly reach the seller in no time, and the availability of stocks can be checked in real time. The purpose of having an inventory is to reduce the overall logistical cost while improving service to customers. Having
11211-598: Was also chosen and was initially planned to support fighter squadrons. The airbase was located approximately 30 miles (48 km) west of Sydney. Bankstown Airport , which was 12 miles (19 km) south west of Sydney, was needed as a Receipt and Despatch Unit and possess the ability for assembling seventy aircraft at first, then rising to two-hundred per month. By May 1945 it was clear the programme of works at these four airfields were overrunning. To mitigate, other airfields that needed less adjustments than those already selected, were considered. These sites were put forward by
11322-568: Was commissioned on 4 September as HMS Flycatcher , Headquarters Mobile Naval Airfields Organisation. The Mobile Naval Airfield Organisation (MNAO) was eventually made up of two different types of unit : the Mobile Operational Naval Air Base (MONAB) and the Transportable Aircraft Maintenance Yard (TAMY). Initially, a Mobile Naval Airfield Unit (MNAU) was the first type of mobile unit conceived. This

A map of New South Wales , Australia, illustrates the Royal Australian Air Force installations , where a Mobile Naval Air Base (MONAB) was established. These include RAAF Station Nowra, which accommodated HMS Nabbington and later HMS Nabswick ; Bankstown Airport,
11544-414: Was designed to have all of the effectiveness of a naval air station , or an aircraft carrier, and could be conveyed to any spot around the world . It was made up of a number of non-technical and technical units. There were non-technical units such as a command & executive unit , a medical unit , stores, a flying control unit and a radio & radar unit. The technical units included componenets such as
11655-489: Was effectively the beginning of the Mobile Naval Airfields Organisation (MNAO). November saw a proposed structure and size for a MNAO and at the beginning of 1944 the plan for the location of operations was likely to be Ceylon. However, in the spring a British Pacific Fleet was to form and the plan for the location of the operations moved to Australia. On 1 August 1944, the formation of a headquarters for
11766-463: Was either coined or popularized by Swiss military officer and writer Antoine-Henri Jomini , who defined it in his Summary of the Art of War ( Précis de l'Art de la Guerre ). The term appears in the 1830 edition, then titled Analytic Table ( Tableau Analytique ), and Jomini explains that it is derived from French : logis , lit. 'lodgings' (cognate to English lodge ), in
11877-475: Was envisaged to be set up in forward areas . The second type of unit devised was a Transportable Air Base (TAB) which was more akin to an aircraft repair yard. Due to the modular "component" system an MNAU could be upgraded to a TAB if required. However, these had developed and renamed Mobile Operational Naval Air Base by the middle of 1944 and there became a type A (Small) and a type B (Large). The former providing mobile maintenance , supporting 50 aircraft and
