Early factories that contained small amounts of machinery, such as one or two spinning mules, and fewer than a dozen workers have been called "glorified workshops".
[1] Most modern factories have large warehouses or warehouse-like facilities that contain heavy equipment used for assembly line production.
Large factories tend to be located with access to multiple modes of transportation, some having rail, highway and water loading and unloading facilities.
In ancient times, the earliest production limited to the household, developed into a separate endeavor independent to the place of inhabitation with production at that time only beginning to be characteristic of industry, termed as "unfree shop industry", a situation caused especially under the reign of the Egyptian pharaoh, with slave employment and no differentiation of skills within the slave group comparable to modern definitions as division of labour.
[7][8][9] A source of 1983 (Hopkins), states the largest factory production in ancient times was of 120 slaves within fourth century BC Athens.
By the time of the fourth century AD, there was a water-milling installation with a capacity to grind 28 tons of grain per day,[24] a rate sufficient to meet the needs of 80,000 persons, in the Roman Empire.
A tenth-century grain-processing factory in the Egyptian town of Bilbays, for example, milled an estimated 300 tons of grain and flour per day.
Josiah Wedgwood in Staffordshire and Matthew Boulton at his Soho Manufactory were other prominent early industrialists, who employed the factory system.
[31] Large scale electrification of factories began around 1900 after the development of the AC motor which was able to run at constant speed depending on the number of poles and the current electrical frequency.
Highly specialized laborers situated alongside a series of rolling ramps would build up a product such as (in Ford's case) an automobile.
The exception proved the rule: even greenfield factory sites such as Bournville, founded in a rural setting, developed their own housing and profited from convenient communications systems.
Manufacturing processes (or their logical successors, assembly plants) in the late 20th century re-focussed in many instances on Special Economic Zones in developing countries or on maquiladoras just across the national boundaries of industrialized states.
[verification needed] Assumptions on the hierarchies of unskilled, semi-skilled and skilled laborers and their supervisors and managers still linger on; however an example of a more contemporary approach to handle design applicable to manufacturing facilities can be found in Socio-Technical Systems (STS).
Production of the Supermarine Spitfire at its parent company's base at Woolston, Southampton was vulnerable to enemy attack as a high-profile target and was well within range of Luftwaffe bombers.
Supermarine had already established a plant at Castle Bromwich; this action prompted them to further disperse Spitfire production around the country with many premises being requisitioned by the British Government.
[39] Connected to the Spitfire was production of its equally important Rolls-Royce Merlin engine, Rolls-Royce's main aero engine facility was located at Derby, the need for increased output was met by building new factories in Crewe and Glasgow and using a purpose-built factory of Ford of Britain in Trafford Park Manchester.
