Systems Engineering

Engineers should press forward with development to meet the diversified needs of people

Engineering is too important to wait for science.

Among the first texts to use the term [Systems engineering] was Louis Ridenour’s Radar System Engineering, published in 1947 as part of the Radiation Laboratory’s series of textbooks. The title refers to the physiological sense of system, that is “how to engineer a radar system,” – where an individual radar is a connected set of components like magnetrons, waveguides, power supplies, and display tubes. Title does not refer to the philosophical sense of system, as in “how to system engineer a radar,” but such ideas are nascent in the book: it covers not only wave propagation and noise models, but also the appropriate design of displays and the dissemination of information through a radar organization. Ridenour’s text includes no discussion of feedback or servomechanisms, or of the dynamic characteristics of radar systems. A McGraw Hill text, System Engineering [by Harry H. Goode, and Robert E. Machol, published ten years later, included probability, analog and digital computers for simulation, queuing theory, game theory, information theory, servomechanism theory, and sections on “human engineering,” management, and economics.
