Abstract: A mission planning rationality evaluation index system is constructed by analyzing the key factors that a ect the rationality of mission planning results. Based on deep learning, a multi-layer neural network operational mission planning rationality intelligent analysis model is established. By integrating the expert evaluation experience and learning continuously, the mapping relationship between each index value and the rationality analysis result is established. The simulation results show that the evaluation model can accurately and e ectively evaluate the rationality of operational mission planning.
