Engineering
Engineering is the creative application of science, mathematical methods, and empirical evidence to the innovation, design, construction, operation and maintenance of structures, machines, materials, devices, systems, processes, and organizations. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering.
Mechanical Engineering
Mechanical engineering is the discipline that applies engineering, physics, engineering mathematics, and materials science principles to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering disciplines.
Production Engineering
Production engineering is a combination of manufacturing technology, engineering sciences with management science. A production engineer typically has a wide knowledge of engineering practices and is aware of the management challenges related to production. The goal is to accomplish the production process in the smoothest, most-judicious and most-economic way.
Production
To those who clamor, as many now do, "Produce! Produce!" one simple question may be addressed:—"Produce what?" ...What can be more childish than to urge the necessity that productive power should be increased, if part of the productive power which exists already is misapplied? Is not less production of futilities as important as, indeed a condition of, more production of things of moment? ... Yet this result of inequality ... cannot be prevented, or checked, or even recognized by a society which excludes the idea of purpose from its social arrangements and industrial activity.
R. H. Tawney, The Acquisitive Society (1920), p. 39.
