人的可靠性综合分析模式及应用

摘要

Enhancing human reliability is the key process for enhancing system reliability .Hence , it is necessary to analyze human reliability .Currently, various human reliability analysis ( HRA) models are used to accomplish this goal .However, these models have their own limits .In order to analyze human er-rors in aviation, three HRA models are applied , including technique for human error rate prediction ( THERP) , cognitive reliability and error analysis method ( CREAM) , and information decision action in a crew ( IDAC) , compared and eventually combined .By establishing an integrated model which makes use of three models'advantages , the human errors in aviation can be effectively analyzed .An example is given to illustrate the application of the proposed model .%提高系统可靠性的关键步骤是提高系统中人的可靠性，这需要对人的可靠性进行分析。当前分析人的可靠性主要依靠运用各类HRA模型，这些模型各有优缺点。为了研究航空人为差错，选取了具有代表性的3个HRA模型，对人的可靠性分析模型THERP（ technique for human error rate prediction ）、CREAM（ cognitive reliability and error analy-sis method ）、IDAC（ information decision and action ）进行了分析。将3种模型进行比较，找出它们的优劣之处，结合3种模型的优点，建立了以THERP模型、CREAM模型以及IDAC模型为主体的人的可靠性综合分析模式，并将该分析模式在航空人为差错分析上进行了应用，并给出实例说明该分析模式的应用。
