ABSTRACT The roll-on/roll-off (Ro-Ro) ships are true workhorses of coastal and deep-sea shipping. They are valued for their versatility to transport heterogeneous cargo and short turnaround times in ports. However, the optimal utilisation of cargo space has been inherently problematic with the Ro-Ro concept. In view of the existing attempts to contrive optimal stowage plans, the paper proposes three practical improvements with respect to the state of the art. The improvements lead to a finer approach to ship stability, fire safety, and cargo handling efficiency when optimising cargo stowage on Ro-Ro decks. Formally, we express the stowage problem as a mixed-integer linear programming (MILP) problem and solve it to optimality. The paper outlines the mathematical formulation, provides a numerical example, and studies practical application aspects.

滚装甲板上的最佳装载效率和安全

摘要 滚装/滚装 (Ro-Ro) 船舶是沿海和深海航运的真正主力。它们因其在港口运输异类货物的多功能性和较短的周转时间而受到重视。然而，货舱的最佳利用一直是滚装概念固有的问题。鉴于现有的设计最佳装载计划的尝试，本文针对现有技术提出了三项实际改进。在优化滚装船甲板上的货物积载时，这些改进为船舶稳定性、消防安全和货物装卸效率提供了更好的方法。正式地，我们将配载问题表示为混合整数线性规划 (MILP) 问题并将其求解为最优。本文概述了数学公式，提供了一个数值例子，并研究了实际应用方面。
