Considering the characters of bp neural network, such as the simple structure, the advisable malleability, self - fitness, self - studying, nonlinear function approximating, the considerable abilities of parallel computing, fault - tolerant and so on, the bp algorithm have been extensively applied to the areas of system modeling, pattern recognition and seismic exploration since 1986. compared with other algorithms, as the above reasons, the bp algorithm has become the most usual and efficient solutions to the artificial neural networks
由於人工神經網路中的bp神經網路結構簡單，可塑性強，具有良好的自適應、自學習、極強的非線性逼近、大規模并行處理和容錯能力等特點，自1986年rumelhart等人提出以來，被廣泛應用於系統建模、模式識別、地震勘探等重要領域。而bp演算法數學意義明確，步驟分明，是神經網路中最為常用、最有效、最活躍的一種方法。 -
This thesis introduces the conception of the system reliability, and analyzes some basic techniques for system reliability systematically, concludes the factors that influence the fault - tolerant real - time system : on the one hand, most of the fault - tolerance systems utilizes the hardware fault - tolerant technique, which improves the system reliability in a certain extent. however, this approach can only solve hardware error, and is helpless to software error. on the other hand, the real - time computing systems are designed decoupling between hardware and software, which is not beneficial for reliability design, especially for the tolerance design of software
本文首先介紹了系統可靠性的基本概念;詳細分析了基本的可靠性保障技術，特別是軟體容錯和硬體容錯的基本技術;歸納了制約容錯技術在實時系統中的應用的兩個核心問題:一是大多數容錯系統以硬體容錯為主，對于軟體錯誤無能為力;二是實時計算機系統設計中軟硬體耦合度低的特點不利於系統可靠性設計，特別是軟體容錯設計;導出了現代錯誤容忍設計急待解決的關鍵問題:確保硬體忍錯，強化軟體容錯，在系統級整合軟、硬體容錯。
