Abstract: To study characteristics and dispatch regulations of the logistics dispatch system in CIMS, the mathematic model was set up, and the simulation analysis was given as well. The system model was depicted by queuing theory, serial as well as parallel queuing model were employed in setting up the system model. In the forms of M/M/1 and M/M/C queuing system, the dispatch regulation was described. Then, the conditions and peculiarity of probability of stably running state of the whole system were attained. Based on the analyses above, some simulation strategies and simulation methods of this kind of system were also introduced. At last, by simulating a real system as well as giving the numerical analysis, corresponding simulation indexes and theoretic indexes were attained, and this testified the correctness of the model for the system discussed.
