Based on the traditional method in solving nonlinear optimization problem without constraint, this paper established a kind of System Dynamics(SD) model to solve the problem and obtained better result than the traditional one by applying the adavantages of SD to the solution. At the same time, this paper proposed the concept of universal memory block in SD model and encapsulated it into module. Then, the validity of application of the SD model to solving the nonlinear optimization is illustrated theoretically. At last, the validity of the SD model to solving the problem and the memory block is verified through a real example.
