Qualitative and Quantitative Prediction of Human Error in Risk Assessment

Qualitative and Quantitative Prediction of Human Error in Risk Assessment 

Given these uncertainties, it becomes even more important that a systematic and comprehensive qualitative method is adopted for identifying the sources of risk and the consequences of failures. Such a procedure must ensure 

In addition, the chapter will provide an overview of htunan reliability quantification techniques, and the relationship between these techniques and qualitative modeling. The chapter will also describe how human reliability is integrated into chemical process quantitative risk assessment (CPQRA). Both qualitative and quantitative techniques will be integrated within a framework called SPEAR (System for Predictive Error Analysis and Reduction).

Chapter 5, Quantitative and Qualitative Prediction of Human Error in Safety Assessments, describes a systematic process for identifying and assessing the risks from human error, together with techniques for quantifying human error probabilities. 

HRA is mainly a predictive tool, intended to estimate the probability of human errors and assess the human factors contribution to the overall risk through the use of qualitative and/or quantitative methods. Essentially, traditional HRA tools consist of (i) the identification of potential human erroneous actions, followed by (ii) the consideration of internal and external factors that could influence the human performance, finally resulting in (iii) the...
