首先,以拟开通的大连港至鹿特丹港北海航道班轮航线为研究对象,以油耗和运营成本最小化为优化目标,将官方已有记载的北海航道通过的货船航速数据输入Eureqa软件,得到航行最高速度f(x)与进入北海航道时间t的拟合度最好的函数公式.在此基础上,构建了北海航道班轮运输排班的数学模型;其次,在仿真实例分析中,选用了5000TEU的集装箱船作为计算参数,将捕食搜索算法运用到数学模型求解之中,并且运用MATLAB软件进行求解,在最快航速受限的前提下,得到单艘班轮最佳往返时间和相同型号班轮的最低配置数目以及在服务周期内班轮公司所要付出的最低运营成本;最后,通过比较研究,得出结论是:最快航速的提高,对于降低北海航线班轮运输的运营成本将起较大作用.
First of all, taking the proposed Dalian Port to the Rotterdam Port Beihai Shipping liner route as the research object, taking the fuel consumption and operating cost minimization as the optimization objectives, the official existing records of the cargo passing speed of the Beihai Waterway are input into Eureqa software to obtain the highest navigation Speed F (x) and the time of entering the North Sea channel time t the best fitting function formula.On this basis, the construction of the Beihai waterway liner scheduling and mathematical model; secondly, in the simulation example analysis, the choice of 5000TEU As a calculation parameter of container ships, the predator search algorithm is applied to solving the mathematical model, and the software MATLAB is used to solve the problem. The optimum round-trip time of one single liner and the minimum configuration of liner of the same model And the minimum operating cost to be paid by liner companies during the service period. Finally, through the comparative study, it is concluded that the increase of the fastest speed will play a greater role in reducing the operating cost of liner shipping on the North Sea route.
