Quantitative Analysis of Error Mode,Error Effect and Criticality

The quantitative method of human error mode,effect and criticality is developed in order to reach the ultimate goal of Probabilistic Safety Assessment.The criticality identification matrix of human error mode and task is built to identify the critical human error mode and task and the critical organizational root causes on the basis of the identification of human error probability,error effect probability and the criticality index of error effect..Therefore,this will be beneficial to take targeted measures to reduce and prevent the occurrence of critical human error mode and task.Finally,the application of the technique is explained through the application example.
