摘要: 为解决客户在线订舱退订概率较高情形下的远洋集装箱班轮舱位分配问题,本文提出一种按有无退订费的两类即期市场客户新划分方式,依据不同时段市场运价指数及其变差系数,设计两类即期市场客户退订概率预测方法,结合货物未出现概率,以船公司收益最大化为目标,建立两阶段舱位分配及即期市场定价的非线性规划模型,以东方海外船公司Paclflc China North1(PCN1)航线为算例,对模型进行分析验证。结果显示:相较于没有退订费,收取退订费的远洋集装箱班轮舱位分配可以提高船公司收益10%以上,船公司设置的长期合同客户置信参数存在一个合理的取值,即期市场客户运价敏感系数增大将导致船公司总收益下降,退订费与船公司即期市场收益呈近以线性关系。研究结论可为船公司班轮运输舱位分配与定价决策提供有益的参考。

Abstract: This paper focuses on the slot allocation for ocean container liners in the case of high probability of customers' online booking cancellation. A new classification method was proposed with two types of customers in the spot market according to whether the booking cancellation fee is charged or not. Two types of forecasting methods of customers' booking cancellation probability in the spot market were designed based on the freight index in different periods. Then, a nonlinear programming model of two-stage slot allocation and pricing in spot market was established with the goal of maximizing the revenue of the shipping companies by combining the probability of the goods not in place. The model was analyzed and verified through the examples of Paclflc China North 1 route of Orient Overseas Container Line (OOCL). The results show that the slot allocation for ocean container liner with booking cancellation fees can increase the revenue of shipping companies by more than 10% compared to callentation without the fees. There is a reasonable value for the long-term contract customer confidence parameter set by the shipping company. The total revenue of the shipping company will decrease with the increase of customers' sensitivity coefficients of freight rate in spot market. There is an approximate linear relationship between the booking cancellation fee and the revenue of the shipping company in spot market. The research conclusion provides a useful reference for shipping companies to make shipping slot allocation and pricing decisions.

Key words: waterway transportation, slot allocation, non-linear programming model, booking cancellation fee, online booking
