VTS雷达站选址优化研究

雷达站选址及雷达配置方案对于提高整个船舶交通管理系统(简称VTS)的运行性能起到重要作用。针对当前VTS雷达站选址模型因较少考虑水域风险和环境遮挡等相关因素而较难进行实际应用的问题,提出了一种基于水域单元风险评价的VTS雷达站选址方法。该方法充分考虑水域风险和环境遮挡等环境因素,利用ArcGIS软件对水域进行划分、风险评价和视域分析,并建立雷达站选址配置双目标优化模型,设计多目标粒子群算法进行求解。最后,通过对肇庆市的VTS雷达站选址项目进行验证分析,结果表明最终方案能够满足模型约束并实现优化,在考虑水域风险、环境遮挡的情况下提高了VTS雷达站的运行效果,推动VTS雷达站选址模型的实际应用。

Model on Location Optimization of VTS Radar Station

The results of radar station location and configuration have an important impact on improving the operational performance of the vessel traffic service(abbreviated as VTS). The dominant location optimization models of VTS radar station is difficult to be applied because the factors of waterway risk and environmental occlusion are less considered in models. To resolve these problems, a optimization method of VTS radar station location and configuration based on water unit risk assessment is proposed. In this method a bi-objective model is proposed after the division, risk assessment and visibility analysis of the water area considering the risk and environmental occlusion factors around the water area by use of ArcGIS software, and a multi-objective particle swarm optimization is designed to solve the model. Finally, an example in Zhaoqing City shows that the final solution can satisfy the constraints in the model, so that the coverage performance of VTS radar station can be improved under the condition that the location result considers the waterway risk and the environmental occlusion, and the practical application of the VTS radar station location is promoted meanwhile.
