Safety and reliability of industrial equipment in the process industries are substantially influenced by degradation processes such as corrosion, erosion, deposits and blocking of pipes. To that end Risk-Based Inspection and Maintenance (RBIM) methodologies are progressively adopted using prediction models that depict the yearly corrosion rate of piping & equipment groups.
Indeed, piping and...
In binary reliability systems, the minimal cut-sets, path-sets and signature vector [1, 2], provide the basis for computing key reliability measures, such as the survival function and the mean time to failure [1, 3]. However, these quantities are typically obtained by exhaustive evaluation of the structure function over the Boolean state space [1], whose size grows exponentially with the...
The generalised F distribution (GenF) has been called an “umbrella” that covers several conventional distributions. In this work, we compare GenF with the Generalised Extreme Value (GEV) distribution with focus on estimation of return levels. Upper-tail asymptotics of the GenF are examined in relation to GEV. Potential numerical challenges in fitting the GenF are discussed. Data sets of river...
