*[[Economic system]]s were recognized by 1776.<ref name="smith76">[[Adam Smith]] [https://standardebooks.org/ebooks/adam-smith/the-wealth-of-nations/text (1776) ''The Wealth of Nations''] Book IV refers to commercial, and mercantile systems, as well as to systems of political enonomy</ref>

**[[Radar system]]s were developed in [[MIT Radiation Laboratory#Formation|World War II]] in subsystem fashion; they were made up of [[transmitter]], [[Radar warning receiver|receiver]], [[power supply]], and [[signal processing]] subsystems, to defend against airborne attacks.<ref>[[MIT Radiation Laboratory]], MIT Radiation Laboratory Series, 28 volumes</ref>
*[[Dynamical systems]] of [[ordinary differential equation]]s were shown to exhibit [[stability theory|stable behavior]] given a [[Control-Lyapunov function|suitable]] [[Lyapunov function#Example|Lyapunov control function]] by [[Aleksandr Lyapunov]] in 1892.<ref name="pates">Richard Pates [https://www.youtube.com/watch?v=uXAx_641FPM (2021) What is a Lyapunov function]</ref>
*[[Thermodynamic systems]] were treated as early as the eighteenth century, in which it was discovered that [[heat]] could be created without limit, but that for [[closed system]]s, [[laws of thermodynamics]] could be formulated.<ref name="beingatoBecoming">{{cite book | authorlink=Ilya Prigogine|last=Prigogine | first=Ilya | year=1980 | title=From Being To Becoming | publisher=Freeman | isbn=0-7167-1107-9 | url-access=registration | url=https://archive.org/details/frombeingtobecom00ipri }} 272 pages.</ref> [[Ilya Prigogine]] (1980) has identified situations in which systems far from equilibrium can exhibit stable behavior;<ref name="G&P1971">Glansdorff, P., Prigogine, I.
