Application of System Dynamics in Public Policy

Today our world is a world of accelerating change. It is a system in which we, as the components, play our own roles whether consciously or unconsciously. The only way to understand the connections and interdependencies of such a huge, complicated and dynamic system is to have a systemic point of view. And public policy which is considered as inherently complicated field must be dealt with a complicated manner. In this regard, the dynamics of the system arises as a multidisciplinary field. System dynamics is a perspective and a set of conceptual tools that enable us to understand the structure and dynamics of complex systems. In this paper, we will pay attention to the relationship between public policy and the global view of system dynamics, how to solve complex problems in the process of policy-making by the means of dynamics of the system, namely the process of dynamic modeling, the causal loop diagram, to convert the causal loop diagram into a cumulative flow diagrams and simulation of models by means of computer software, and eventually the potential contributions of systems techniques to matters related to public policy.
