摘　　要：研究了铁水运输系统的建模与仿真问题,建立了三层控制结构的智能运输仿真模型,基于OOCPN建立底层工位的状态演化模型,通过仿真进程控制层驱动调度决策层·利用消息传递机制沟通状态变迁与仿真策略之间的关系,利用分层调度和调度精化思想设计的调度决策专家系统和避碰决策专家系统有效模拟了现实系统中铁水运输调度员和机车司机的智能决策行为·仿真结果表明智能仿真模型为运输调度系统的建模与仿真提供了一种实用的解决方案·Modeling and simulation of molten iron transport system are studied to develop a tri-layer intelligent simulation model. Based on OOCPN, a model of state evolvement is also developed available to the working position at the bottom layer, and the layer of scheduling is driven by the layer of simulation process control. The message transfer mechanism communicates well with the relation between state transition and simulation strategy efficiently. The intelligent decision-making behavior of dispatcher and engine driver in actual system is simulated efficiently by the expert systems for scheduling and collision avoiding decisions, which are both designed conceptually using hierarchical and carefully checked scheduling schemes. The results show that the intelligent simulation model developed provides a practical solution for the modeling and simulation of a transport scheduling system.
