基于改进BP算法的复杂武器系统健康状态评估

Evaluation of Health State for Complex Weapon System Based on Improved BP Arithmetic

根据复杂武器系统指标体系的确定原则:系统性原则、完整性原则、独立性原则、可比性原则、可操作性原则和定性与定量相结合的原则,建立了某复杂武器系统健康指标体系;分析了基本BP神经网络的优点及BP算法的缺陷,研究了一种改进的BP算法;建立了某复杂武器系统健康管理BP神经网络结构;对某复杂武器系统健康状态进行了评估,验证了指标体系的合理性。

According to the principle of index system for weapon system： systemic principle, integ- rity principle, independence principle, the comparability principle, operational principle and the princi- ple of combining qualitative with quantitative, the health index system of one complex weapon system is set up; the advantage of BPNN and the disadvantage of BP arithmetic is ananyzed, and one improved BP arithmetic is put forward ; the BPNN structure of one complex weapon system is based ; the health state of the complex weapon system is evaluated, and the rationality of index system is validated.
