Evidential network-based failure analysis for systems suffering common cause failure and model parameter uncertainty

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2018
The fault tree analysis has been extensively implemented in failure analysis of engineered systems. In most cases, the probabilities of basic events, e.g. components’ failures, are represented by crisp values in the fault tree analyses.

Parameter Uncertainties Characterisation for Linear Models.

IFAC Proceedings Volumes, 2006
Abstract Parameter estimation mainly consists in characterising a parameter set consistent with measurements, the model and the equation error description. The problem to be solved is that of finding the set of admissible parameter values corresponding to an admissible error. The uncertainties must be treated by a global analysis of the problem: both

Uncertainty of Hydraulic Parameters

Journal of Hydraulic Engineering, 1996
Reliability analysis and other probabilistic techniques are becoming increasingly important tools in hydraulic modeling and decision making. Probabilistic and reliability analyses are based on knowledge of the underlying parameter uncertainties. Hydraulic variables, such as roughness coefficient, channel slope, and critical shear stress, common to many

Estimation and Impact Assessment of Input and Parameter Uncertainty in Predicting Groundwater Flow With a Fully Distributed Model

Water Resources Research, 2017
We present a general and flexible Bayesian approach using uncertainty multipliers to simultaneously analyze the input and parameter uncertainty of a groundwater flow model with consideration of the heteroscedasticity of the groundwater level error ...

Uncertainty of Parameter Estimation

IFAC Proceedings Volumes, 1985
Abstract A procedure is proposed for expressing and handling uncertainties of parameter estimation. It is based on the least squares method and is conform with the German draft standard DIN 1319 Part 4 for the treatment of uncertainties in the evaluation of measurements.

Operator orthogonality and parameter uncertainty

Physics Letters A, 1982
Abstract The relationship between mutually orthogonal matrices and orthogonal operators is established and it is shown that parameters associated with orthogonal operators have minimal errors.

Recursive utility and parameter uncertainty

Journal of Economic Theory, 2019
Abstract We explore how the Epstein–Zin utility captures an agent's sensitivity to parameter uncertainty. Our main result is a closed-form representation of the Epstein–Zin utility for an i.i.d. consumption process with unknown parameter, as the discount factor approaches 1.

Prediction with Parameter Uncertainty

1992
The model is the same one that introduced the Bayesian paradigm in Chapter 2. Observations have been obtained from a random variable with known general form, but unknown parameters. Of interest is the value of a future observation whose distribution also depends on these parameters. Of course, this is the traditional actuarial problem. The observations

Output feedback H∞ control of systems with parameter uncertainty

, 1996
This paper deals with H ∞ control problem for systems with parametric uncertainty in all matrices of the system and output equations. The parametric uncertainty under consideration is of a linear fractional form. Both the continuous and the discrete-time
