The production systems of the Industrial Age and the large scale systems typical of post-Word War II technology have led engineers to take into consideration not only machines and physical equipment and tools but also abstract objects such as “information”, “decisions”, “quality”. The emphasis on process technology, that is, the planning and control of physical processes as well as information flows, has grown with the evolution of mass production methods, automation, control, communications, and information technologies, and has become a characteristic of modern engineering. The core of such technological developments is theoretical, mathematical based research following new approaches such as those typical of operations research and syste...
