A Human Error-based Risk Assessment Model

Abstract

A major component of risk assessment is that of human error. Identifying and calculating overall risk requires that the analyst consider how operators, maintainers, and support staff contribute to the causes of hazardous conditions that may lead to serious, disastrous, or catastrophic consequences. A computerized model has been developed by Rhodes & Associates Inc. to be run for marine, aviation, and rail operational scenarios. The model automatically calculates predicted risk values. The author will present the model’s components and describe how the model may be applied to nuclear operations.
