As the world around us is marked by the increasing complexity and rapid transformation, we often find our knowledge and skills limited or insufficient. Sudden disasters surprise us with growing frequency. Well-meant strategies, plans and technologies, aimed at solving problems, often make the situation even worse or bring about new problems. Effective decision making in complex systems requires a complete transformation of both reasoning and problem analysis, since it demands a holistic, systems approach.
System dynamics is a new field that encompasses an array of conceptual tools and computer modeling methods. Computer simulation models enable us to examine the dynamics of the future and the past, thus giving the opportunity to design more effective strategies and organizations. Within the scope of system dynamics applications there are: business planning, management, social systems modeling, as well as energy and natural environment simulations. It is a rapidly evolving methodology: in the last decade many leading corporations, consulting firms and governmental agencies employed system dynamics methodology for solving key problems.
