摘　　要： 为解决内河集装箱码头大量等待作业的拖车引起港口外围交通要道阻塞的问题,通过优化拖车到达调度,采用非平稳泊松过程,模拟进港拖车到达规律,建立了适合珠三角内河集装箱码头进港拖车到达作业流程的混合Petri网（hybrid Petri net,HPN）模型和优化调度方案.根据HPN模型对佛山市三水港建立了Arena仿真模型,使用过程分析器（process analyzer,PAN）确定拖车的最优到达批量并检验优化效果,仿真结果表明：拖车到达调度优化后,拖车等待时间可减少87%,等待数量减少了26%,调度优化有效地缓解了港口拖车排队导致的交通阻塞问题. To solve the problem with excessive trailers obstructing major traffic paths outside container terminals,a hybrid Petri net（ HPN） model with optimal scheduling strategy is created by optimizing trailer arrivals using non-stationary Poisson distribution to simulate arrival pattern. It can be applied to trailer arrivals and operation process of inland container terminals in the Pearl River Delta. Based on the HPN model,an Arena simulation model of Sanshui Port is constructed,where data is collected and analyzed through a process analyzer（ PAN） to calculate the number of trailers per arrival and hence evaluate the effectiveness of scheduling strategy. Simulation results show that the obstruction can be effectively alleviated by optimizing the scheduling strategy,while the waiting time of trailers and the quantity of awaiting trailers are reduced by up to 87% and 26% separately after optimization.
