Abstract

Probabilistic risk assessment (PRA) is not new to the system designer. To the operational manager, however, PRA is virtually unknown. This paper explores the emerging process of socio-technical probabilistic risk assessment (ST-PRA) that is being used by operational managers to identify and mitigate operational risks within complex socio-technical systems such as aerospace and healthcare. What are the strengths of modeling socio-technical risks using fault trees, and what are the limitations of fault trees and the probability estimates inherent in probabilistic risk assessment?
