Fucheng Qiu, Yi Li · 2014
The scientific and accurate forecast of air traffic flow is not only an effective protection to maintain the air traffic flow continued and unimpeded, and also is an important basis for the air traffic flow management(ATFM) to make decisions and development strategies. Based on the character of flow prediction, the prediction method of genetic algorithm to optimize wavelet neural network is proposed. It uses genetic algorithms with the natural evolution laws to conduct the pre-optimized training for the connection weights and stretching translation scales of the wavelet neural network, overcoming the drawbacks of easy to fall into local minima and causing oscillation effect of wavelet neural network with a single gradient descent method. The air flow prediction simulation using the GA-WNN prediction model demonstrates the validity of the model.
