基于风险耦合理论的航空装备本质安全管理研究

为提高航空装备的本质安全管理水平，奠定新一代航空装备安全服役的良好基础，基于目前本质安全管理理论片面强调组成元素自身本质安全度的提高，忽略系统组元间耦合交互作用的现实，提出了一种基于风险耦合理论的航空装备本质安全管理模型。对航空事故本质致因和耦合风险理论进行了分析，指出耦合风险的原因主要在于各系统组元在容错性、兼容性和标准化等方面存有缺陷。构建了基于耦合理论的飞机本质安全管理图示模型，强调系统宏观安全度的提高在于组元的本质安全化和对组元内部及组元之间耦合风险的有效管控，建立了系统安全度和耦合风险度计算模型，为航空装备服役安全性的提高提供了新理念。

Inherent safety management of aviation equipment based on risk coupling theory

In order to improve the inherent safety management level of aviation equipment, establish the good foun- dation. As the safety service of the next generation aviation equipment, for the fact that present inherent safety man- agement theory unilateralism emphasize the improvement of the personal inherent safety degree of system elements, and ignore the coupling interaction, a aviation equipment inherent safety management model was proposed which based on risk coupling theory. The theory of risk coupling and aviation accident essence causation were analyzed. The main reason for the coupling risk consist of the initial defectiveness of system elements＇ error-tolerance ability, compatibility and standardization. And the aircraft inherent safety management chart model based on coupling theo- ry was set up, which emphasize that the improvement of system macroscopical safety consist of the inherent safety of system elements and the effective management and control of the coupling risk in and between the system elements. The system safety degree model and coupling risk degree calculational model were gained, which provide new sense for improving the service safety of aviation equipment.
