Abstract:Logistics simulation has already shown its important function gradually in our country, but the level of logistics and the ablity of research and application in our country is not developed completely. The absent of the abundant information and the decision support of logistics simulation system has caused the blindness and the loss of the fund when logistics enterprise or enterprise logistics face the problems of the logistics engineering invest for a new project or rebuilding based on the original system. Logistics simulation is real simulation to logistics system by dint of computer technology. And it attains each kind of dynamic activity and the process instantaneous imitates record through the simulation experiment, and then validates the validity, rationality and optimized effect of the logistics engineering project creation. So logistics simulation has its important sense. This paper mainly introduces the function of logistics simulation, the characteristic of several common logistics simulation software, using two kinds of typical simulation software, Flexsim and RaLC, to analyse the application process and the simulation effect of logistics simulation software.
