Abstract

In the air cargo context, pallet loading faces substantial constraints and item heterogeneity. The stability constraint in the pallet loading problem is highly important due to its impact on the efficiency, security, and resulting costs of an air cargo company. In information systems that support pallet loading, physical simulations provide a realistic approximation of a pallet’s stability. However, current approaches neglect the opportunity to integrate physical simulations in underlying solvers. In this research, we propose and compare two approaches for integrating a physical simulation as a fixed component of the problem-solving heuristic and include irregular shapes. Our results achieve runtimes that meet air cargo requirements; therefore, assumptions about the cargo, e.g., shape assumptions, can be relaxed.

航空货物托盘装载静态稳定性评估中物理模拟的集成
在航空货运环境中,托盘装载面临着很大的限制和物品的异质性。托盘装载问题中的稳定性约束对航空货运公司的效率、安全性以及由此产生的成本有着重要的影响。在支持托盘装载的信息系统中,物理模拟提供了托盘稳定性的真实近似值。然而,目前的方法忽略了在底层求解器中集成物理模拟的机会。在这项研究中,我们提出并比较了两种方法,将物理模拟集成为问题解决启发式的固定组件,并包括不规则形状。我们的结果达到符合航空货运要求的运行时间;因此,关于货物的假设,例如,形状假设,可以放松。
