摘要
通过模拟自动小车存取系统(AVS/RS)中任务的动态排队过程,建立了一个基于动态排队网络的系统分析与决策模型。首先,描述了AVS/RS的系统构架、运行规则及任务场景概率。接着,根据系统任务特征构造了一个动态排队网络模型(DQNM)。最后,运用改进的聚合法对该系统模型进行求解,并对系统性能进行分析。分析表明,该模型能够找出系统的最佳小车-电梯组合方式,从而为优化系统的设计、提高设备的利用率、节约系统运行成本提供决策支持。
Through simulating the dynamic queuing process of the tasks in AVS/RS, the system analysis and decision making model based on dynamic queuing network is established. Firstly, the architecture, operation rules and probability of task scenaries of AVS/RS are described. Then the dynamic queuing network model （ DQNM ） is constructed in accordance with the characteristics of the system tasks. The system model is solved using the improved polymerization method ; and the performance of the system is analyzed. The analysis show that this model is able to find out the optimal combination mode of vehicles and lifts, thus it provides decision support for optimizing system design, enhancing the equipment utilization and saving system operating costs.
