A calculation model of airspace utilization rate is proposed based on flight time, the space and capacity of airspace, in order to assess the airspace usage effectively. First, based on the time division multiplexing characteristic of airspace, a definition and a common computing formula of the airspace utilization rate are introduced; Second, the computing formula of the airspace utilization rate...
With the increase of air transportation demand, the problem of air traffic congestion has become more and more serious, so the study of flow optimization management is of urgent need and great importance. Ground-holding policy (GHP) is regarded as one of the most effective methods of short-term air flow management to ease the air traffic congestion and improve the air safety. The essence of the GHP...
Cruising process is an important flight phase, which has a direct impact on the economy of airplane operation. This paper presents the target function and relevance constraint conditions by applying the flight performance principle. Then the paper employs the simulated annealing algorithm to find the optimal solution of a new model, and gives the detailed cruising fuel conservation strategies. Finally...
With the rapid increase of the air traffic transportation, the air traffic congest problem became more and more severity, so to study the flow optimization problem is very importation and urgent. In this paper, such items have been considered: the sectors capacity constrains, the air traffic flux controlled by the area controllers, the time of flight take-off controlled by the town controllers, the...
When air traffic congestion happens, the optimization adjustment on the order for approach landing flights can reduce the air traffic congestion and the flightspsila delay, improve the safety of flying, and reduce the economy cost. For the flights sequencing problem of multi-runway in the terminal area, the model was given according to the least total cost of flights delay, then the ant colony algorithm...
