为了分析任意AGV系统在选定的车辆路径策略下的操作，我们提出了一个仿真模型，该模型可以处理多个系统布局，不同数量的AGV和不同数量的行人在系统中移动。我们介绍了一个动态的车辆路径策略的基础上分层模拟，其操作如下：在主模拟的AGV的每个路由决策的时间，子模拟产生的每一个不同数量的替代路线，并在这些子模拟中观察到的性能，然后使用在主模拟的路由决策。一个案例研究说明了这一战略的优势。
To analyze the operation of an arbitrary AGV system under selected vehicle routing strategies, we present a simulation model that can handle multiple system layouts, a varying number of AGVs, and a varying number of pedestrians moving around the system. We introduce a dynamic vehicle routing strategy based on hierarchical simulation that operates as follows: at the time of each routing decision for an AGV in the main simulation, subsimulations are spawned for each of a varying number of alternative routes; and the performance observed in these subsimulations is then used to make the routing decision in the main simulation. A case study illustrates the advantages of this strategy.
