本文从发货人的角度出发，考虑了不同运输方式的成本函数，建立了一个包含运输方式决策的全球生产-运输计划模型。我们提出了不定期运输、班轮运输和混合运输方式来选择最优的运输方式，在给定的网络条件下，考虑转运和拼装，以发挥规模经济。我们给出了不稳定模式、线性模式和混合模式的数学公式，并应用混合线性整数规划的分段逼近技术来线性逼近凹极小化问题，并使用现成的求解器有效地求解该问题。为了验证所提模式的有效性，通过数值算例对这三种模式进行了比较和讨论。讨论了这三种模式在不同情况下的优缺点。建立了支持生产-运输计划选择最优运输方式的决策辅助系统。
This study develops a global production–shipping planning model that incorporates a decision on transportation mode after considering the cost function of different transportation modes from the shipper’s point of view. We propose tramp shipping, liner shipping, and a mixed mode to select the optimal shipping mode, considering transshipment and consolidation to exploit economies of scale under a given network. We present mathematical formulations of tramp, liner and mixed modes and apply a piecewise approximation technique with mixed-linear integer programming to linearly approximate the concave minimization problem and efficiently solve it using an off-the-shelf solver. In order to verify the effectiveness of the proposed modes, the three modes are compared and discussed in numerical examples. The advantages and disadvantage of the three modes are discussed under different situations. The result is a decision aided system to support production–shipping planning in selecting the optimal transportation mode.
