In recent years, the public has been paying ever greater attention to problems related resilience, since resilience presents recovery ability increasing complexity and vulnerability of disturbances. Many researches have performed address networks disruptions in manufacturing. However, a systematic method model analyze maintenance scheduling disturbed production line system is not well developed. This paper considers resilience-driven methodology under resource constraints for simplified...

The emergency response capability of civil aviation airports is the core to ensure efficient handling emergencies. dynamic characterization multi-scenario evolution paths emergencies in and quantitative targeted evaluation have become study foci urgently needed be solved by current academic circles airport departments for management. To clarify mechanism, paths, this first constructed pressure-state-response (PSR) network expression scenario airports. Then, path scenarios probability...

The 10,000-hour rate of civil aviation incidents is an important index parameter to measure flight safety. Predicting the development trend plays role in accident prevention and safety decision-making. Many complex factors influence occurrence incidents, so changes randomly volatilely. This study proposed idea prediction by combining grey GM (1, 1) model Markov model. Specifically, was constructed using statistical data on China during 2005–2020. On this basis, a established. 2021 based two...

The reliability level of electric light aircraft is the core index to judge flight safety this type vehicle. As such, developing an objective measure determine such has been focus current research in industry and academia. In study, a analysis system that includes four first-level indexes 14 second-level was constructed for from perspective intrinsic safety. Based on failure mode effects criticality (FMECA), table depicting probability main components elements subsequent designed. Then,...

A relevant evaluation index system was established in this study for the objective measurement of emergency management capability urban flood disasters based on four stages response, namely, “prevention, early warning, and recovery.” The weight distribution different indices calculated by using CRITIC method, which generated an cloud a result model. case Zhengzhou City Henan Province “7.20 Flood Disaster” conducted, results were displayed intuitively as digital features model computational...

Aviation emergency rescue plays a crucial role in the management of various events. Consequently, processes identifying relevant constraints aviation ability, analyzing interactive relationship among factors, and putting forward an economical effective improvement strategy for capabilities have become widely popular scholars. To greatly improve economic input efficiency capabilities, 18 influencing factors were screened identified from four perspectives: system institutionalization,...

The coating of aluminum-based aircraft skin can be damaged because complex flight environment during service, which restricts the sustained airworthiness and safety operation.The focus existing studies regarding field surface technology has been on identifying influencing factors organic coatings analyzing dynamic association patterns between factors.To extract more risk for failures define their conduction path systematically comprehensively, leading research literature related to failure...

The reliability level of electric light aircraft is the core index judging safety its flight.In this paper, theory and method determination Rui-Xiang are studied from perspective intrinsic safety.On basis Extensive research data analysis, it studies to determine basic structure composition, discusses key components critical degree calculation method.Then, using FME(C)A identify landing gear systems, harm calculate components.The with comprehensively analysis.The results can provide...

In order to explore the electrostatic decay characteristics of fuel tanks system filled with reticulated polyurethane foam, small scale "circular impingement" test is conducted. Through fitting voltage vs. time nonlinear least squares fitting, parameters formula are solved, and empirical expression foam concluded, which accords classic exponential physical model fairly.

Boilers BLEVE are among the most devastating accidents likely in chemical process industry, which lead to shock waves and rocketing fragments of ruptured vessels. The prediction boiler explosion energy its impact is fairly helpful prevention protection accidents. Phast software used for quantitative assessment a consequence through build-up pertinent model paper, affords results form simulation charts reports with energy, blast-wave overpressure effect radius, positive phase impulse as well....

The airworthiness certification system based on Visual Basic was developed. is applicable to safety assessment of in the initial airworthiness. It works review process as main line, technical points core. key technologies include tree maps all subsystems, orders subsystems should obey, and methods apply subsystems. contains more than 260 related regulations, 40 10 kinds methods, number interface also above 300. structure very clear, simple operation, technology requirements access.

Fatigue failure issues of runway at airports have become one core tasks in airport safety management. How to recognize fatigue risk factors concrete runways and implement a quantitative assessment on risks is key topic that studied the industrial circle academic present. For this reason, an integral analysis internal external causes was carried out, which recognized extracted 18 factors.
