Abstract:

As a key indicator to measure the combat effectiveness of an aircraft carrier, the carrier aircraft's sortie rate is very important for the safe and efficient operation of the carrier-based aircraft system. Establishing a model that predicts the current sortie rate based on real-time data will provide an important reference for the aircraft carrier commander's real-time scheduling. Firstly, starting from the original data of indicators, based on big data correlation analysis, community discovery, and principal component analysis, the tree-like relationship between indicators is determined, so as to establish a sparse deep neural network. At the same time, in order to ensure better training effect, standardization, L2 regularization, and Adam optimizer are selected as the optimization algorithm of the neural network. The simulation results show that the proposed method can achieve fast, accurate and real-time prediction of the sortie rate of carrier aircraft under the mission of continuous dispatch.

Key words: carrier aircraft's sortie rate, sparse depth neural network, Adam optimizer, date standardization, regularization
