Abstract

Human reliability is an important aspect of risk analysis focusing on the identification, analysis and quantification of the causes, contributions, and occurrences of human failure. This review focuses on the state of development of technology of human reliability aspects with regards to the models, methods and their applicability to address the present scenario. Human reliability assessment methods have been in place since past few decades, but the growing emphasis is due to applicability of those methods in the changing main control room atmospheres which are drastically changing from analog to digital and complex interfaces. Also the emphasis is being laid on individual, crew and organizational factors. Due to lack of adequate data the existing models rely on expert elicitation and simulator based data which may have inherent bias due to difference in interfaces and environment. The development of newer models becomes challenging due to less data with regards to emergency conditions or adverse conditions in control room. This review emphasis on the development of a model which incorporates the existing models with Bayesian Approach which can cater to varied data sources like simulator logs, expert opinions and control room data simultaneously to give better estimates of human errors and their mitigation strategies.
