The annual System Dynamics conference brings together people from around the world to share important research and application results and to build the community of those active in the field. The conference theme is “Good governance in a complex world.” Decision making by government, business, and the public is increasingly interdependent. In this conference we aim to address the role of models in governance in the public and private sectors, typically involving a diversity of domains, disciplines, organizations, stakeholders, policies, and goals.
