Abstract: Aiming at the traditional evaluation methods has disadvantage of strong subjectivity and defects of BP neural network, the combinational algorithm PCA-GA-BP based on data is established. Sample data dimensions are reduced by principal component analysis, the initial weights and threshold of BP neural network are optimized by genetic algorithm. The neural network is trained by historical data and can be used to evaluate real-time information, and algorithm is validated through the case analysis. The results show that, the algorithm is feasible, which is suitable to condition evaluation for complex weapon equipment.
