在客户对多式联运承运人的选择过程中,各承运人之间的竞争不仅只有价格竞争,还包括除价格因素以外的深层次竞争。由于托运人对多式联运承运人选择的结果是多样性的,其数量是模糊不确定的,因此使用混合集合规划将最优解以集合形式表示,并将参与人数量用集合的基来表示,可以降低问题的求解难度。 In the customer’s choice of multimodal carrier, the competition among carriers is not only the price competition, but also the deep competition besides the price factor. Because the shippers’ choice of multimodal carriers is diverse and the number of them is ambiguous, the optimal set of solutions is expressed in terms of sets using a mixed set plan, and the number of participants is expressed in a set basis , Can reduce the difficulty of solving the problem.
