【摘要】：跑道入侵危险分析对有效预防跑道入侵的发生至关重要。目前,针对跑道入侵的危险识别与分析多以头脑风暴的方式进行,自动化支持程度较低。为了提高跑道入侵危险分析的规范性和自动化支持,避免过分依赖自然语言进行描述,提出基于危险与可操作性分析和本体技术的危险分析方法。基于业务流程建模与标注和本体推理技术对跑道入侵进行危险与可操作性分析危险识别。建立跑道入侵发生场景模型,应用危险与可操作性分析方法对跑道入侵发生场景开展危险分析。建立危险与可操作性节点分析本体,构建概念间的术语集合描述逻辑关系并实施推理。对跑道入侵危险因素进行定性定量分析。根据危险与可操作性分析的危险识别结果,对危险因素进行发生场景分析,创建事故树,开展跑道入侵危险因素的定性、定量分析。其中定量分析采用层次分析法确定基本事件的权重,得到基本事件发生概率。基于本体技术设计了一种跑道入侵风险分析本体。跑道入侵风险分析本体基于事故树分析理论和跑道入侵风险评估理论,包含事故树和风险分析两个顶层的类。构建一个计算机可复用的通用跑道入侵风险分析本体,该本体利用本体的可复用性、知识获取、形式化描述以及可推理能力可以实现对跑道入侵的风险分析,为下一步实现推理操作提供了事实基础。结果表明,基于危险与可操作性分析和本体技术的危险分析方法能够在形式化逻辑推理的支持下识别出系统内复杂交互行为带来的危险,是一种比传统危险分析更为有效的方法。
[Abstract]:Runway intrusion risk analysis is very important to prevent runway intrusion. At present, the risk identification and analysis of runway intrusion is mostly conducted by brainstorming. In order to improve the normative and automated support of runway intrusion risk analysis, we can avoid over-reliance on natural language description. A hazard analysis method based on hazard and maneuverability analysis and ontology technology is proposed. Hazard identification and operability analysis of runway intrusion based on business process modeling and tagging and ontology reasoning technology are carried out. Runway entry is established. Invasion scenario model. The hazard and maneuverability analysis method is applied to analyze the risk of runway intrusion scene, and the ontology of hazard and maneuverability node analysis is established. Construct the set of terms between concepts to describe the logical relationship and carry out reasoning. Qualitative and quantitative analysis of runway intrusion risk factors. According to hazard and operational analysis of the risk identification results. The occurrence scene analysis of risk factors, the creation of accident tree, the qualitative and quantitative analysis of risk factors of runway intrusion are carried out, in which AHP is used to determine the weight of basic events. Based on ontology technology, a runway intrusion risk analysis ontology is designed. The runway intrusion risk analysis ontology is based on accident tree analysis theory and runway intrusion risk assessment theory. It consists of two top-level classes of accident tree and risk analysis. It constructs a general-purpose runway intrusion risk analysis ontology which can be reused by computers. The ontology utilizes the reusability of ontology and acquires knowledge. Formal description and reasoning ability can be used to analyze the risk of runway intrusion, which provides a factual basis for further reasoning operation. The results show that. The hazard analysis method based on hazard and maneuverability analysis and ontology technology can identify the danger caused by complex interaction behavior in the system with the support of formal logic reasoning. It is a more effective method than traditional hazard analysis.
