Price system was analyzed by a nonlinear stochastic dynamic model with the supply and demand factors. This model converged to a process in probability. Then the stability of the system was analyzed by the result of drift coefficient and diffusion coefficient of the process. Numerical simulation results of the stationary probability density with different conditions were shown. It can be concluded...
A nonlinear dynamic price model considering the nonlinear factors between supply and demand was constructed in this paper. And the meanings of each parameters in the model were explained. By using nonlinear dynamic analysis, the system stability conditions were obtained from the analysis of the model. By numerical simulation of the model with MATLAB, the influence of different parameters on the system...
The nonlinear dynamic characteristics of traffic flow based on continuous car-following model were studied in this paper. Discrete Bierley car-following model was transformed into continuous nonlinear dynamic model with nonintegral dimension in difference method and solved in averaging method. Stability and bifurcation characteristics were analyzed, and time histories and phase diagrams of this system...

A stochastic model of business cycle was presented in this paper. The Ito diffusion process was obtained after the model was simplified in quasi Hamiltonian theory. The backward Kolmogorov equation for reliability function and the generalized Pontryagin equation for conditional moment of the first-passage time were established, and the numerical results were given in virtue of figures according to...
