【摘要】：环保意识增强、航运市场低迷等原因迫使航运公司不得不在保证船队运输任务的前提下,降低燃油的消耗以减少对海洋造成的污染和运营成本.燃油的消耗与航速相关,而航速的确定又受风、浪等气象条件的制约.在考虑气象因素的基础上,建立了风、浪影响下的混合整型非线性(MINP)航速优化数学模型.由于MINP的复杂性,使模型求解困难,因此从船舶实际工作情况出发,对航速进行离散,将该混合整型非线性模型转化成混合整型线性模型(MILP),利用CPLEX软件包进行求解,极大地提高了运算效率.通过速度离散转化为线性模型的方法,可以计算出不同风、浪条件下班轮运输各航段的最优航速和每条航线上船舶配备的最佳数目.仿真算例表明,该方法能够为班轮公司提供合理、可靠的船舶调度方案和决策支持.
[Abstract]:The enhancement of environmental awareness and the downturn in the shipping market forces shipping companies to reduce the consumption of fuel to reduce the pollution and operating costs of the ocean, under the premise of ensuring the transport task of the fleet. The consumption of fuel is related to the speed of the ship, and the determination of the speed is restricted by the weather conditions such as wind and waves. At the same time, a mathematical model of mixed integer nonlinear (MINP) speed optimization is established under the influence of wind and waves. Because of the complexity of MINP, the model is difficult to solve. Therefore, from the actual working situation of the ship, the speed is discrete, and the mixed integer nonlinear model is transformed into a mixed integer linear model (MILP), and the solution is solved by the software package of CPLEX. It can greatly improve the efficiency of operation. Through the method of velocity discrete transformation into a linear model, the optimal speed of different wind and wave conditions can be calculated and the optimal number of ships on each route is calculated. The simulation example shows that the method can provide a reasonable and reliable ship scheduling scheme and decision for the liner department. Support.
