System dynamics is an approach to understanding the behaviour of complex systems over time. It deals with internal feedback loops and time delays that affect the behaviour of the entire system. What makes using system dynamics different from other approaches to studying complex systems is the use of feedback loops and stocks and flows. System dynamics is a powerful methodology and computer simulation modeling technique for framing, understanding, and discussing complex issues and problems. Originally developed in the 1950s to help corporate managers improve their understanding of industrial processes, system dynamics is currently being used throughout the public and private sector for policy analysis and design. System dynamics is an aspect of systems theory as a method for understanding the dynamic behavior of complex systems. The basis of the method is the recognition that the structure of any system — the many circular, interlocking, sometimes time-delayed relationships among its components — is often just as important in determining its behavior as the individual components themselves. Examples are chaos theory and social dynamics. It is also claimed that because there are often properties-of-the-whole which cannot be found among the properties-of-the-elements, in some cases the behavior of the whole cannot be explained in terms of the behavior of the parts.

Dynamics of systems where the ultimate beneficiary is the macro or national or state or panjayat or global human society at large is very complex to be captured in mathematical format of intricate complex equations not made use of perhaps by the policy makers and decision makers .
The simulation may be a tool which should enable researchers, the policy makers and the decision makers to test the various alternative policies which have subjective content as well , for the benefit of the mankind.

The dimensions of research areas in the system dynamics modeling have got direct impact on the human beings. In order to boost the pace, ACEEE-SDSG has International Journal of Systems Dynamics Modelling & Simulation (IJSDM&S) to cover the following area. The journal deems to have a research forum where the scientists who study the dynamics of systems which have a direct bearing on the mass human population directly or indirectly, but not at the individual or micro level.
