Special Issue Information

Dear Colleagues, 

Nonlinear dynamics with multiscale variables are common phenomena in physics and chemistry. The connections between microscopic stochastic models and macroscopic continuum models are built by statistical mechanics and probability limiting theory, including the law of large numbers, the central limit theory and the large deviation principles. The resulting nonlinear dynamics usually possess some generic structures, such as the gradient flow dissipation structure and the conservative Hamiltonian flow structure. Applied mathematicians can understand these complicated nonlinear dynamics in physics and biochemical reactions using various methods, including numerical analysis and modelling. Any related methods, new ideas and practical algorithms are welcome to solve those nonlinear dynamics for fundamental scientific problems.

Topics of interest include, but are not limited to: 

  • Multiscale modelling: microscopic stochastic models and fast–slow nonlinear dynamics;
  • Continuum limit theory: thermodynamic limit, large population mean field limit, and convergence analysis for interacting particle systems;
  • Numerical simulation for stochastic differential equations and macroscopic partial differential equations;
  • Stochastic algorithms: ensembled statistical properties, rare event simulation, important sampling, Bayesian inference, variational methods for structure-preserving schemes, stochastic optimal control simulation and deep learning for dynamic systems.

In this paper, an output dynamic game model of intertwined supply chains operating in two different countries is established. The Nash equilibrium point of the model and its stable region are obtained using nonlinear dynamic principles. The complex properties of the system, such as stability, period-doubling bifurcations, and chaos, are investigated using numerical simulations. Our results suggest that the level of output and the system’s profits undergo bifurcation and chaos with an increase in the output adjustment speed. An interesting phenomenon occurs in that higher tariffs lead to the expansion of the stable range of the supply chain in the product-exporting country. The chaotic behavior of the system is sensitive to the value of the initial level of output. In supply chain competition, each supply chain firm should make suitable adjustments to the speed of output. To maintain the stability of domestic markets, excessive tariffs should be avoided. It is essential that each supply chain firm evaluates the potential impacts of different initial output values when making initial decisions. Using the method of delayed feedback control, the chaotic behavior of the system can effectively be controlled. These findings offer valuable and novel insight into inter-chain competition in supply chain networks. Full article
