Abstract

fetched live from OpenAlex

Problemas de capacidade de pista estão presentes em vários aeroportos ao redor do mundo. A execução eficiente e eficaz do sequenciamento de aeronaves para pouso tornou-se uma alternativa para o aumento de capacidade de pista no nível tático. O problema do sequenciamento busca determinar a melhor ordem de processamento de aeronaves para pouso, a fim de otimizar o uso da pista e mitigar atrasos, entre outros objetivos, sujeito a uma série de restrições operacionais. O presente estudo tem por objetivo desenvolver um método de solução para o problema de sequenciamento que seja capaz de produzir um ganho de capacidade de pista, gerar soluções viáveis em um curto espaço de tempo e manter a equidade entre as empresas aéreas, respeitando o número máximo de mudanças de posição das aeronaves em uma nova sequência. O método é baseado na metaheurística de arrefecimento simulado adaptado ao contexto do problema estudado. O conjunto de dados Airland, disponível na OR-library, e dados reais do Aeroporto Internacional de São Paulo/Guarulhos foram utilizados para avaliar os potenciais benefícios do método proposto. Os resultados mostraram ganhos de capacidade de até 21% para os dados teóricos e de 10% para os dados reais.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
