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.
Production
Production systems which are technologically the most advanced are also the least adaptable and work to the longest time scale of decision making. These are the process industries (chemical plants, oil refineries and so on) in which vast resources are invested in the creation of a closely programmed and tightly controlled process which will continue to perform the same task over a very long period.
