本文研究了班轮运输在各种规则性不确定性和突发事件下的实时船期恢复策略。目的是以最有效的方式恢复受影响的时间表。本文的一个重要贡献是明确区分了班轮运输中的两类不确定性，并提出了不同的处理策略。该问题可以表述为一个多阶段的随机控制问题，最大限度地减少总的期望燃料成本和延误惩罚。对于规则的不确定性，可以通过适当的概率模型的特点，我们开发的最优控制策略的属性，然后我们展示了一个新兴的中断可能会改变控制策略。数值研究表明，实时调度恢复策略对一些典型的替代品的优势。(C)2015爱思唯尔有限公司版权所有。
This paper studies real-time schedule recovery policies for liner shipping under various regular uncertainties and the emerging disruption event that may delay a vessel from its planned schedule. The aim is to recover the affected schedule in the most efficient way. One important contribution of this work is to explicitly distinguish two types of uncertainties in liner shipping, and propose different strategies to handle them. The problem can be formulated as a multi-stage stochastic control problem that minimizes the total expected fuel cost and delay penalty. For regular uncertainties that can be characterized by appropriate probabilistic models, we develop the properties of the optimal control policy; then we show how an emerging disruption may change the control policies. Numerical studies demonstrate the advantages of real-time schedule recovery policies against some typical alternatives. (C) 2015 Elsevier Ltd. All rights reserved.
