Modeling and Simulation of Channel scheduling system under Intermittent Fault Conditions

With the increasing trend of ship traffic volume and ship size, there are more requirements for navigable conditions. However, due to the factors like the limited dimensions, some channels are difficult to meet the needs of free navigation for large ships, which causes intermittent congestion in waterways, restricting the smoothness of the traffic flow, especially in large port waters. In this paper, the ship traffic in restricted channels is divided into the regular traffic flow and the fault-caused traffic flow according to the occupation of channel resources by ships. Based on the assumption, the intermittent relative fault fairway system model is constructed, and the simulation experiment is conducted by taking the “Tiaozhoumen channel” in “Zhoushan” waters as a case study. The results show that the model can well reflect the real-time utilization of waterway under various traffic density. The simulation model has significant theoretical and practical meanings for the effective organization of the overall traffic flow, which can be extended to be applied to similar types of busy and restricted channels.
