摘要
在舰船最优航线规划的过程中,使用传统航线计算方法存在着准确性低的问题,为此通过引入迭代偏微分方程的方法设计最优舰船航线计算模型。首先按照舰船航线的计算特点构建航线规划偏积分方程,在此基础上对航线信息迭代更新,同时得出迭代值与更新结果,最终得出舰船航线中航程与航向的计算结果。通过仿真实验发现使用传统的计算方法对舰船航线进行计算,其准确率为81.46%,而偏微分方程迭代计算模型的准确率为97.72%。
In the process of ship optimal route planning, there is a problem of low accuracy in the traditional route calculation method. Therefore, an iterative partial differential equation method is introduced to design the optimal ship route calculation model. Firstly, the partial integral equation of ship route planning is constructed according to the calculation characteristics of ship route. On this basis, the route information is updated iteratively. At the same time, the iteration value and update result are obtained. Finally, the calculation results of ship route and course are obtained. Through simulation experiments, it is found that the accuracy of traditional calculation method is 81.46%, while the accuracy of partial differential equation iteration calculation model is 97.72%.
