CIMS物流调度系统的建模与仿真

为了研究CIMS物流调度系统的性能及调度规则,建立了系统的数学模型,并对系统进行了仿真分析。该模型采用排队论进行描述,利用串行与并行排队模型对系统原型进行建模;通过M/M/1系统与M/M/C系统相结合,描述系统的调度规则;求得系统达到稳态工作状态的条件及其概率特性;探讨了该类系统的仿真策略与仿真算法。最后,通过对真实系统的仿真分析和数值计算,获得系统运行的各项仿真指标及相应的理论指标,验证了系统模型的正确性。

Modeling and simulation of logistics dispatch system in CIMS

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.
