Research on international logistics dynamics with uncertain exchange rate

The movement of exchange rate influences the equilibrium of entire international logistics system. Based on reviewing literature on international logistics optimisation, exchange rate risk and multi-product flow are first attempted to be integrated into international logistics dynamic model. The decision-making purpose of the model is to maximise expectation revenue with psychological anticipation. And then more reliable equilibrium transaction volume and equilibrium transaction price are found out. Using projection gradient algorithms, numerical simulation and stability analysis are presented by MATLAB software. The convergence effect and stability of simulation result prove the validity of multi-product dynamic international logistics system model with uncertain exchange rate.
