In the vast majority of airports where demand exceeds capacity, landing and take-off slots are allocated according to the process established by the Worldwide Slot Guidelines (WSG). An optimization-based decision-support tool is introduced in this paper to assist slot coordinators in the initial slot allocation – the most important stage of that process. The WSG comprises both primary and additional criteria to be taken into account by slot coordinators at this stage. Considering all additional criteria specified in the WSG, this tool generates, in an acceptable amount of time, alternative efficient slot allocations against which the coordinators can evaluate the solutions obtained through the heuristic methods they apply. The decision-support tool also offers solution analysis features, such as visualization, ranking, comparison of multiple optimal solutions, and comparison of solutions regarding important characteristics not reflected in the WSG additional criteria. The tool is being tested at one of the largest airports worldwide – Guarulhos (Sao Paulo, Brazil) – with results that clearly illustrate its usefulness in practice.

在需求超过容量的绝大多数机场中，起降时隙是根据《全球航班指南》（WSG）建立的过程分配的。本文介绍了一种基于优化的决策支持工具，以协助插槽协调员进行初始插槽分配，这是该过程的最重要阶段。在此阶段，WSG包括时隙协调员要考虑的主要和附加标准。考虑到WSG中指定的所有其他标准，此工具会在可接受的时间内生成替代的有效时隙分配，协调者可以根据这些时隙分配，评估通过其应用的启发式方法获得的解决方案。决策支持工具还提供解决方案分析功能，例如可视化，排名，比较多个最佳解决方案，以及比较未包含在WSG附加标准中的重要特征的解决方案。该工具正在全球最大的机场之一-Guarulhos（巴西圣保罗）进行测试，结果清楚地表明了该工具在实践中的实用性。
