A framework for risk-based assessment using loss functions
This paper presents a quantitative risk assessment method using loss function that enables the analysis of operational performance in chemical processes. This method helps to overcome the existing challenges in assessing impacts of deviations of process variables. In this paper, the modified inverte...
