Influences of variables on ship collision probability in a Bayesian belief network model
Maritime accidents Bayesian networks Sensitivity analysis Mutual information Causation probability
2012/4/15
The influences of the variables in a Bayesian belief network model for estimating the role of human factors on ship collision probability in the Gulf of Finland are studied for discovering the variabl...
Methodology for estimating the probability of failure by sliding in concrete gravity dams in the context of risk analysis
Dam safety Structural reliability Risk analysis Numerical modeling
2012/4/26
Dam safety based on risk analysis methodologies demand quantification of the risk of the dam-reservoir system. This means that, for a given initial state of the system, and for the several failure mod...
Estimating separation distance loss probability between aircraft in uncontrolled airspace in simulation
Uncontrolled airspace Collision probability Statistics Rare event Quantile estimation Importance splitting
2012/4/12
In this article, collision probability between aircraft in uncontrolled airspace is estimated. For that purpose, a large database of aircraft trajectories in the vicinity of Saint-Cyr-l扙cole airfield ...
Estimating Human Error Probability using a modified CREAM
Human Error Probability Human reliability CREAM Common performance condition
2012/4/22
Human Error Probability (HEP) point estimation is important for Probabilistic Safety Assessment (PSA) of socio-technical systems. We present a modified basic method of CREAM to provide the point estim...
An inexpensive estimate of failure probability for high-dimensional systems with uncertainty
Robustness Reliability High-dimensional systems Non-linear systems Crash analysis Bayesian inference
2012/4/26
The failure probability of a system at an uncertain state can be estimated within a precise confidence interval using the Monte-Carlo sampling technique. Using this approach, the number of system para...
Study on probability distribution of fire scenarios in risk assessment to emergency evacuation
Risk assessment Fire scenario Event tree Monte Carlo simulation Evacuation
2012/4/22
Event tree analysis (ETA) is a frequently-used technique to analyze the probability of probable fire scenario. The event probability is usually characterized by definite value. It is not appropriate t...
