Industrial engineering is an engineering profession that is concerned with the optimization of complex processes, systems, or organizations by developing, improving and implementing integrated systems of people, money, knowledge, information, equipment, energy and materials
Industrial engineers use specialized knowledge and skills in the mathematical, physical and social sciences, together with the principles and methods of engineering analysis and design, to specify, predict, and evaluate the results obtained from systems and processes. From these results, they are able to create new systems, processes or situations for the useful coordination of labour, materials and machines and also improve the quality and productivity of systems, physical or social. Depending on the sub-specialties involved, industrial engineering
may also overlap with, operations research, systems engineering, manufacturing engineering, production engineering, supply chain engineering, management
engineering, financial engineering, ergonomics
or human factors engineering, safety engineering, or others, depending on the viewpoint or motives of the user. There is a general consensus among historians that the roots of the industrial engineering
profession date back to the Industrial Revolution. The technologies that helped mechanize traditional manual operations in the textile industry including the flying shuttle,the spinning jenny, and perhaps most importantly the steam engine generated economies
of scale that made Mass production in centralized locations attractive for the first time. The concept of the production system had its genesis in the factories created by these innovations. Eli Whitney and Simeon North proved the feasibility of the notion of Interchangeable parts in the manufacture of muskets and pistols for the US Government. Under this system, individual parts were mass-produced to tolerances to enable their use in any finished product. The result was a significant reduction in the need for skill from specialized workers, which eventually led to the industrial environment to be studied later.
