摘要：
本文针对船舶装卸问题，讨论了时间效率与能量效率之间的权衡。考虑了集装箱高度约束以及能量消耗与再生。我们在此前工作的基础上，引入了一个适用于处理集装箱避碰约束的坐标系，并加入了与能量相关的建模。除了改变坐标系外，标准的图集重构还得到了一个具有改进数值性质的最优控制问题。通过在代价函数中对总时间和能量消耗进行加权来处理这一权衡。文中提供了一个示例，表明在保持大致相同装卸时间的同时，可以显著降低能量消耗。
英文摘要：
This paper addresses the trade-off between time- and energy-efficiency for the problem of loading and unloading a ship. Container height constraints and energy consumption and regeneration are dealt with. We build upon a previous work that introduced a coordinate system suitable to deal with container avoidance constraints and incorporate the energy related modeling. In addition to changing the coordinate system, standard epigraph reformulations result in an optimal control problem with improved numerical properties. The trade-off is dealt with through the use of weighting of the total time and energy consumption in the cost function. An illustrative example is provided, demonstrating that the energy consumption can be substantially reduced while retaining approximately the same loading time.
