摘要: 根据长江航道特点为长江沿岸矿石港口集群提供最佳的航线设计。该航线通过考虑船舶的航行受到航道等级及港口潮汐的影响、船舶的燃油消耗受到船速与载重量的影响进行建模。通过将提出的模型应用于实际案例,发现在求解大规模算例时存在一定局限性。因此,提出了一种针对内河运输遗传算法的解决方案。通过对比,发现该算法在求解精度上与Lingo方法近似相等,在解效率上显著提高,从而验证了该算法的高效性。

Abstract: According to the characteristics of the Yangtze River channel, the best route design was provided for the ore port cluster along the Yangtze River. The proposed route was modeled by considering the ships navigation affected by channel class and port tide as well as the fuel consumption of the ship affected by ship speed and load capacity. By applying the proposed model to the actual case, it was found that there were certain limitations in solving large-scale examples. Therefore, a solution scheme of genetic algorithm for inland river transportation was proposed. Through comparison, it is found that the solution accuracy of the proposed algorithm is approximately the same as Lingo method, and the solution efficiency of the proposed algorithm is significantly improved, which verifies the efficiency of the proposed algorithm.
