  • Approximate uncertainty modeling in risk analysis with vine copulas 
    Bedford, Tim; Daneshkhah, Alireza; Wilson, Kevin J. (Wiley, 2015-09-02)
    Many applications of risk analysis require us to jointly model multiple uncertain quantities. Bayesian networks and copulas are two common approaches to modeling joint uncertainties with probability distributions. This ...
  • Assessing parameter uncertainty on coupled models using minimum information methods 
    Bedford, Tim; Wilson, Kevin J.; Daneshkhah, Alireza (Elsevier Science B.V., Amsterdam., 2014-05-31)
    Probabilistic inversion is used to take expert uncertainty assessments about observable model outputs and build from them a distribution on the model parameters that captures the uncertainty expressed by the experts. In ...
  • Human reliability analysis: A critique and review for managers 
    French, Simon; Bedford, Tim; Pollard, Simon J. T.; Soane, Emma (Elsevier Science B.V., Amsterdam., 2011-07-01)
    In running our increasingly complex business systems, formal risk analyses and risk management techniques are becoming a more important part of a manager's tool-kit. Moreover, it is also becoming apparent that human ...
  • A role for human reliability analysis (HRA) in preventing drinking water incidents and securing safe drinking water 
    Wu, Shaomin; Hrudey, Steve E.; French, Simon; Bedford, Tim; Soane, Emma; Pollard, Simon J. T. (Elsevier Science B.V., Amsterdam., 2009-05-05)
    The prevalence of water quality incidents and disease outbreaks suggests an imperative to analyse and understand the roles of operators and organisations in the water supply system. One means considered in this paper is ...
