基于MATLAB编程求解船舶最佳航速

摘要

All the actual expenditure and the time schedule requirements of a ship voyage are fully considerated.A practical speed optimization model of a ship voyage is set up in terms of least total voyage expenditure.The outer point penalty function and the Powell algorithm are used for solving the constrained nonlinear problem,because they are easier for MATLAB programming.The numerical examples show the validity of the model and the program.The influence of oil price change on economic speed is highlighted,which provides reliable decision-making information for ship' s navigation plan.%充分考虑船舶航次的所有实际支出和船舶到港时间要求,以航次总支出最少为目标,建立更符合实际的船舶最佳航速优化模型.采用更易MATLAB编程的外点惩罚函数和鲍威尔算法对模型中的有约束非线性问题进行求解.通过算例分析验证该模型和程序的有效性,讨论燃油价格变化对经济航速的影响,为船舶航次规划提供可靠的决策信息.
