System dynamics is grounded in control theory and the modern theory of non-linear dynamics. There is an elegant and rigorous mathematical foundation for the theory and models we develop. System dynamics is also designed to be a practical tool that policy makers can use to help them solve the pressing problems they confront in their organizations. Realistic and useful models are almost always of such complexity and nonlinearity that there are no known analytic solutions, and many of the mathematical tools you have studied have limited applicability.
Them, I draw attention a set of papers that have applied used fuzzy logic
In order to get a general idea of what is Fuzzy Logic, I recommend a list of 8 books. It will
