Human Error Quantification Techniques: A Brief Review

Quantification of human errors is not an easy task in any of the industry. With reference to construction industry, due to scarcity of databases no proper move until now has been done. But without databases it seems quite possible to quantify the human errors as behavioural aspects of humans more or less the same in every industry. The main aim of this study is to pinpoint the negligence of geotechnical/construction industry in relation
with human errors or human uncertainties. Till now no concept of taking Human reliability analysis into
consideration, in spite of their beliefs that human errors/human uncertainty exists. Human reliability analysis
proposed different models and methods to pinpoint and quantify human performances as human performances
sometimes becomes big threat to structural reliability. Slope failures/slope instability is also most of the times are the outcome of deficit design, flaws in construction or poor maintenance of the structures used to strengthen the
slopes. Among different techniques discussed in this study, author’s choice is to recommend the model of heart for
Human Reliability Assessment. The reason of selecting this model of heart is transparent, as this model has also
been tailored before by Air Traffic Management and Railways. In other words it works well or it has the flexibility to adjust with any other industry.
