Abstract
There is a continuous debate about the proper role of man and machine in complex operational frameworks. Formal human analyses and risk management techniques are becoming more important part to manage the relationship between human factors and accident analyses. There are different types of Human Reliability Analysis (HRA) models. HRA methods differ in their characteristics but a common feature in all methods is the definition of the human error probability (HEP). The aim of this chapter is not to cover all of the possible HRA approaches and above not from a mathematical point of view but conceptual one. In fact, no one approach can answer all of the separate issues that can arise in human reliability. The utility of a particular approach is a function of a number of components, not just the absolute value of a method. Expert judgment is an integral part of HRA to capture information about human actions. Definitively, the aim of this chapter is twofold. It tries to respond to these questions: What is HRA? and What are the main features of the most well-known HRA methods?I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
