The purpose of the Society is to promote the development of all aspects of complex systems science in the countries of Europe, in relation with the whole international scientific community

The Society will, in the European context, aim to promote complex systems research (pure and applied), 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 European complexity scientists, and represent the European complexity community at all international levels.

The Complexity Society provides a focal point for people in the UK interested in complexity. It is a community that uses complexity science to rethink and reinterpret all aspects of the world in which we live and work.

The purpose of ONCE-CS is to strengthen European research in complex systems, and to assist people in business and public services to use the new science with the following activities.

• Conferences and Workshops
• Education
• Widening the COmmunity

The Complex Systems Network of Excellence, "Exystence" is funded by the European Commission to develop collaboration among European researchers interested in Complex Systems, from fundamental concepts to applications, and involving academia, business and industry.
