World of Systems

On the ISSS Home Page is a feature box called "World of Systems". This page is a replica and explaination.
The Systems "Field" or "World" encompasses a wide variety of themes and topics. This page one kind of capture of this variety captured in different kinds of maps.
The ISSS is one of the oldest organizations dedicated to the study, development and application of systems science, systems thinking, cybernetics and complexity science. 
We are assembling lists of organizations, social network pages and groups, and also maps of the evolution of the field of systems and cybernetics. Here are some examples
Systems Maps  Created using The Brain software. Compiled by Peter Tuddenham 9/22/2017 from various sources. Unfortunately the sources were not connected at time of compilation. Credit is given to authors when possible. Additions and suggestions please contact Peter Tuddenham.
Systems and Cybernetics World  Created using The Brain software. A list of websites related to "Systems"
Streams of System Thought  This is a map created in The Brain software by Peter Tuddenham and Marc Peirson that is based upon an original document called Streams of System Thought. 
Some Streams of Systemic Thought KEY: (Draft update — May 2001)  Originated in 1996 by Dr. Eric Schwarz, Neuchâtel, Switzerland. 
Extended in 1998, including items from the The Story of Philosophy by Will Durant (1933).
Elaborated in 2000-2001 from many sources for the International Institute for General Systems Studies. 
Tom Marzolf's Systems Common Model July/August 2023
Tom Marzolf's Systems Common Model October 2021    This is an ongoing personal project by ISSS member Tom Marzolf to map all of "systems" as he sees it. Updated to Version 5 30 Oct 2021. 
What is new with V5.0:
entry to main menu is streamlined
menu is reorganized to emphasize views over elements; also many elements have been extended into views
explicit request for comments is added (see upper right of menu); this includes suggested topics on which to comment
rough hierarchy of model elements from left column is removed to avoid confusion (and control access)
many items added
Collection Views: Mathematicians
Concept Views: DIKW Pyramid
Courses: BFO
Documents and On-line Documents: (many added); new link to On-line Documents on Menu
Field Views: Deep Ecology, Systems Chemistry, Systems Geography
Organization Views: Club of Rome, ISKO, ISSP, sLAB, System Organization
People Views: Bailey, Dostal, Fleischaker, Grinspoon, Haken, Haldane, Henderson, Johannson, Maxwell, Metcalf, Muller, Otlet, Pangaro, Parsons, Priest, Rapoport, Rovelli, Shirky, Barry Smith, Ulrich, Wallenstein, Wells, A. G. Wilson, Woese
Quotations: (many)
School Views: Vienna Circle
Theme Views: Coherence Fit, System-Parts Difference, Transdisciplinerians
Theory Views: Conversation Theory, Overview
Other: many added references to Wikipedia entries and other related on-line items, many fixes to broken links, etc.

Principia Cybernetica tries to tackle age-old philosophical questions with the help of the most recent cybernetic theories and technologies.
This is the website of the Principia Cybernetica Project (PCP), an international organization. The Project aims to develop a complete philosophy or "world-view", based on the principles of evolutionary cybernetics, and supported by collaborative computer technologies
International Encyclopedia of Systems and Cybernetics  2nd Edition, as published by Charles François 2004 Presented by the Bertalanffy Center for the Study of Systems Science Vienna for public access
Gene Bellinger's System Relationships Learning Over the past 4+ decades of developing relationship models there have been numerous insights that would have served Gene well had he had them earlier along the journey. The associated relationship model is an attempt to surface those Gene found most beneficial along with thoughts about how they might be related. Note that each version of this presentation tends to evolve a bit.
