Human Risk Assessment and Mitigation Using Bow Tie Strategy

Human reliability assessment (HRA) techniques are used for quantifying human error probability for the purpose of providing feedback regarding the overall performance, and most importantly, safety of the system. Performing HRA involves various activities, including task analysis, conducting experiments, which have been found generally difficult, time-consuming and costly. In this project, the whole process will be based on HRA methodology. For problem identification, a survey and interview are conducted. The task analysis of the finding was then constructed and the cause of human error is identified using human HAZOP and to be considered in Fault Tree Analysis (FTA) while all the controls will be developed. The Event Tree Analysis then developed based on consequences of the human error and all the control will be developed as well. The analysis then combined and Bow-Tie analysis is developed.
