Editing Complex system (section)

== Types of systems ==
Complex systems can be:

* [[Complex adaptive system|'''Complex adaptive systems''']] which have the capacity to change.
* '''Polycentric systems :''' “where many elements are capable of making mutual adjustments for ordering their relationships with one another within a general system of rules where each element acts with independence of other elements”.<ref>{{Cite book |last=McGinnis |first=Michael Dean |url=https://books.google.fr/books?hl=fr&lr=&id=iBZ32c7KLWUC&oi=fnd&pg=PR7&dq=Ostrom,+V.:+Polycentricity%E2%80%94Part+1.+In:+McGinnis,+M.+(ed.)+Polycentricity+and+Local+Public+Economies:+Readings+from+the+Workshop+in+Political+Theory+and+Policy+Analysis,+pp.+52%E2%80%9374.+Ann+Arbor:+University+of+Michigan+Press+(1999)&ots=fdCuq3RBdG&sig=J0kD615t-MQoqJpPdAOPLztAItA |title=Polycentricity and Local Public Economies: Readings from the Workshop in Political Theory and Policy Analysis |date=1999 |publisher=University of Michigan Press |isbn=978-0-472-08622-1 |language=en}}</ref>
* '''Disorganised systems''' involving localized interactions of multiple entities that do not form a coherent whole.<ref>{{Cite journal |last=Weaver |first=Warren |date=1948 |title=Science and Complexity |url=https://www.jstor.org/stable/27826254?casa_token=oSX1jnUm6kwAAAAA:vCzb9BmMEXeUT0dyEcXrNb-mzBla72WBdv6n9ONubllSBVNDDjdwUsOWmXPT3iua5dPtGuOc2jz6UvvIlnBcuq4vyawpKqmo_RSBxgr2QYoSP2BFh2Q |journal=American Scientist |volume=36 |issue=4 |pages=536–544 |issn=0003-0996}}</ref> Disorganised systems are linked to [[Self-organization|self-organisation]] processes.
* '''Hierarchic systems''' which are analyzable into successive sets of subsystems.<ref>{{Cite journal |last=Simon |first=Herbert A. |date=1962 |title=The Architecture of Complexity |url=https://www.jstor.org/stable/985254 |journal=Proceedings of the American Philosophical Society |volume=106 |issue=6 |pages=467–482 |issn=0003-049X}}</ref> They can also be called nested or embedded systems.
* '''[[Cybernetic system|Cybernetic systems]]''' involve information feedback loops.
