är det ämnesövergripande <a href="/wiki/Vetenskap" title="Vetenskap">vetenskapliga</a> studiet av <a href="/wiki/System" title="System">system</a> i allmänhet. Målet är att beskriva <a href="/wiki/Princip" title="Princip">principer</a>, som kan tillämpas på alla typer av system på olika nivåer och inom olika vetenskaper. I systemteoretiska sammanhang används ordet ’system’ specifikt med syftning på självreglerande system, det vill säga system som korrigerar sig själva genom återkoppling. Ett system är inom denna referensram sammansatt av grupper av aktiviteter som regelmässigt berör eller påverkar varandra. Självreglerande system finns förutom i många teknologiska tillämpningar också i naturen, till exempel i de <a href="/wiki/Fysiologi" title="Fysiologi">fysiologiska</a> systemen i vår kropp, i psykologiska <a href="/wiki/Inl%C3%A4rning" title="Inlärning">inlärningsprocesser</a>, i lokala och globala <a href="/wiki/Ekosystem" title="Ekosystem">ekosystem</a>, samt i <a href="/wiki/Klimat" title="Klimat">klimatet</a>. </p><p>Systemteori kan betraktas som en specialisering och precisering av systemtänkande eller en generalisering av <a href="/wiki/Systemvetenskap" title="Systemvetenskap">systemvetenskap</a>. Själva termen har sitt ursprung i den generella systemteori som <a href="/wiki/Ludwig_von_Bertalanffy" title="Ludwig von Bertalanffy">Ludwig von Bertalanffy</a> utarbetade med utgångspunkt från <a href="/wiki/Biologi" title="Biologi">biologins</a> område, och som senare vidareutvecklades inom <a href="/wiki/Sociologi" title="Sociologi">sociologin</a> av <a href="/wiki/Talcott_Parsons" title="Talcott Parsons">Talcott Parsons</a> och <a href="/wiki/Niklas_Luhmann" title="Niklas Luhmann">Niklas Luhmann</a>. </p><p>Systemteorins <a href="/wiki/Tv%C3%A4rvetenskap" title="Tvärvetenskap">tvärvetenskapliga</a> karaktär gör att principer sammanförs från många vetenskapsområden, så som <a href="/wiki/Vetenskapsteori" title="Vetenskapsteori">vetenskapsteori</a>, <a href="/wiki/Fysik" title="Fysik">fysik</a>, <a href="/wiki/Informatik" title="Informatik">informatik</a>, <a href="/wiki/Biologi" title="Biologi">biologi</a>, <a href="/wiki/Ekologi" title="Ekologi">ekologi</a>, <a href="/wiki/Ingenj%C3%B6rsvetenskap" title="Ingenjörsvetenskap">ingenjörsvetenskap</a>, <a href="/wiki/Geografi" title="Geografi">geografi</a>, <a href="/wiki/Sociologi" title="Sociologi">sociologi</a>, <a href="/wiki/Autopoiesis" title="Autopoiesis">autopoiesis</a>, <a href="/wiki/Statsvetenskap" title="Statsvetenskap">statsvetenskap</a>, <a href="/wiki/Ekonomi" title="Ekonomi">ekonomi</a>, <a href="/wiki/Psykologi" title="Psykologi">psykologi</a> och filosofisk <a href="/wiki/Ontologi" title="Ontologi">ontologi</a>. Matematisk analys av <a href="/wiki/Dynamiska_system" class="mw-redirect" title="Dynamiska system">dynamiska system</a> och <a href="/wiki/Kaosteori" title="Kaosteori">kaosteori</a> är grenar av matematiken som utnyttjas systemteoretiskt. </p><p>Det ligger i systemteorins karaktär att teorin utvecklas genom analys av de system som studeras. När systemteoretiska begrepp och principer tillämpas inom olika vetenskaper medför detta också att teorin utvecklas och prövas. Inom ekologin har bland andra <a href="/wiki/Howard_T._Odum" title="Howard T. Odum">Howard T. Odum</a>, <a href="/wiki/Eugene_Odum" title="Eugene Odum">Eugene Odum</a> och <a href="/wiki/Fritjof_Capra" title="Fritjof Capra">Fritjof Capra</a> arbetat med systemteori. <a href="/wiki/Karl_W._Deutsch" title="Karl W.
