Bayesian Fuzzy Regression Analysis and Model Selection: Theory and Evidence

In this study we suggest a Bayesian approach to fuzzy clustering analysis – the Bayesian fuzzy regression. Bayesian Posterior Odds analysis is employed to select the correct number of clusters for the fuzzy regression analysis. In this study, we use a natural conjugate prior for the parameters, and we find that the Bayesian Posterior Odds provide a very powerful tool for choosing the number of ...

Risk Analysis of Drinking Water Systems by aggregation of Fuzzy Fault Tree Analysis with Bayesian networks and Dempster-Shafer theory

Safekeeping of drinking water supply makes efficient risk management necessary for urban water systems as an important infrastructure. Before decision making about possible risk reduction measures, an effective risk assessment model should be applied to analyze different hazard events that water utilities may face them. In other hand, the World Health Organization emphasizes the use of an integ...

Bayesian Networks and Evidence Theory to Model Complex Systems Reliability

This paper deals with the use of Bayesian Networks to compute system reliability of complex systems under epistemic uncertainty. In the context of incompleteness of reliability data and inconsistencies between the reliability model and the system modeled, the evidence theory is more suitable to manage this epistemic uncertainty. We propose to adapt the Bayesian Network model of reliability in o...

Fuzzy model for risk analysis

The goal of this paper is to show how the concept of fuzzy logic can be used to establish a degree to which an investment project belongs to a class of risk. Also, the probability of the fuzzy event is presented and is ap-plied to calculate the probability of the fuzzy event “the project X is a good investment”. This process has to enable the decision maker to compare several alternative invest...

Combining Evidence in Risk Analysis using Bayesian Networks

This paper is about helping people who make critical decisions improve the quality of their judgements. We provide a brief introduction to Bayesian Nets (BNs) and use an example in safety assessment. We show how BNs enable decision-makers to combine different types of evidence (including subjective judgements) to provide quantitative, auditable arguments. By using state-ofthe-art BN technology ...
