【摘要】 北煤南运网络作为一个复杂的多式联运网络,网络中各个节点相互影响、相互制约,作为一个整体决定着煤炭运输网络系统的效率。通过Petri网刻画煤炭多式联运网络的相互关系,对其网络结构形式进行深入研究,从整个煤炭运输网络的角度研究煤炭运输的影响机理。建立基于witness平台的煤炭仿真模型,评价网络效能并揭示瓶颈,实现资源利用及效率的优化研究。更多还原

【Abstract】 In this paper, we depicted the relationships in the multimodal coal transport network using the Petri nets, studied in depth its network structure form and investigated in the influence mechanism of the coal transport process from the perspective of the entire coal transport network. Then we established a coal transport simulation model based on the Witness platform to evaluate the performance of the network, reveal its bottleneck links, and realize efficient and optimized resource utilization.更多还原
