The purpose of the Society is to promote the development of all aspects of complex systems science in the countries of Europe, as well as the whole international scientific community. See CSS Statutes and CSS By-Laws.
The Society will aim to promote complex systems research pure and applied (What are Complex Systems?), assist and advise on problems of complex systems education, concern itself with the broader relations of complex systems to society, foster the interaction between complex systems scientists of different countries, establish a sense of identity amongst complexity scientists, and represent the complexity community at all international levels.
It is regulated by a CSS Council and by a CSS Executive Committee.
The Society was first launched at a European level on 7th Dec 2004 during The European Conference on Complex Systems at Foundation ISI in Torino, Italy. It became an international society in 2006 during the ECCS06 Conference in Oxford.
Since 2004, the European Conference on Complex Systems organized by the CSS, is the most important annual meeting for the complex systems research community.
