采用故障树分析法分析火灾报警系统的失效风险,得出影响火灾报警系统的底事件。利用BP神经网络算法结合模糊算法建立系统失效风险评估模型,并通过MATLAB仿真说明模型性能优良,满足要求。
Fault tree analysis method is used to analyze the failure risk of fire alarm system and obtain the bottom event that affects fire alarm system. Using BP neural network algorithm and fuzzy algorithm to establish the system failure risk assessment model, and through MATLAB simulation shows that the model performance is good and meets the requirements.
