A system dynamics approach is a simulation method in solving real-world problems to describe relationships among variables in complex real systems. System Dynamics is a computer-based mathematical modeling approach for strategy development and better decision making in complex systems. . What is development dynamic? Representative regulatory motifs for the generation of nonlinear dynamics. SD was developed by Jay Forrester in the 1960's. He was interested in modeling the dynamic behavior of systems such as populations in cities, or industrial supply chains. Namely, it is a field interested in problems to be solved, situations that need to be better understood, or undesirable behaviours that need to be corrected or avoided (Forrester, 1993 ). The field of system dynamics is still growing, but it is becoming well-known for its powerful approach to complex systems.

SD has been applied in some studies for shared understanding of healthcare problems, hypothesis testing, and generation of scenarios as well as group learning [ 19 - 21 ]. Much of the literature reviewed points to SD as being a valid tool for large, complex projects. This study exemplifies the advantage of using the system dynamics approach when the past pattern is not a good predictor for the future by making predictions based on how the system works. The dynamics of a system are the result of the interplay of both positive and negative feedback processes.
