In order to solve the problem of lack of data in human reliability analysis,a hierarchical human reliability data classification was developed based on SRK（skill,rule and knowledge） model,which includes a classification of human error modes and a classification of performance shape factors.Then,base human error probability was determined according to some practical human error data and some experimental data.In the extrapolation system,AHP was used to quantify the level of context;furthermore,base human error probability and context were comb...
