GPU accelerated risk quantification
<p>Factor Analysis of Information Risk (FAIR) is a standard model for quantitatively estimating cybersecurity risks and has been implemented as a sequential Monte Carlo simulation in the RiskLens and FAIR-U applications. Monte Carlo simulations employ random sampling techniques to model certain …

A cost benefit analysis of operational risk quantification methods for regulatory capital
Operational risk has attracted a sizeable amount of attention in recent years as a result of massive operational losses that headlined financial markets across the world. The operational risk losses have been on the back of litigation cases and regulatory fines, some of which originated from the …

Application of Supply Chain Risk Management through visualization and value-at-risk quantification
Supply Chain Risk Management ("SCRM") is often discussed in business and academia but is still underdeveloped as a practical tool. Many studies have examined the effects of supply chain disruptions, and many studies have also produced tools for mitigating risk. However, there is still a need for an …

A Methodology to Assess Data Variability and Risk in a Pavement Design System for Bangladesh.
… to develop a generic methodology to quantify the risk and reliability of pavement and embankment design for Bangladesh considering the variability in design data. The study also aimed to develop a construction quality control procedure to reduce the variability in data. To achieve this aim, data …

Methodologies to strategize the utilization of modeling and simulation for probabilistic risk assessment (PRA) of nuclear power plants: Applications in fire PRA
Based on the literature, one way to conceptualize risk is: Risk={A,C,P_f^*,P(P_f^* ) | U^',K}, where A represents events including initiating events and scenarios; C denotes the consequences of these events (A); P_f^* stands for the estimated frequency of occurrences of events A; P(P_f^* ) is a …
