| Abstract: | Because of being difficult to determine the failure probability of bottom events in the quantitative analysis of a solid rocket motor failure tree, an engineering method (,i.e expert grading method), which is used to determine the failure probability of bottom events, is presented. By using it, structure reliability of the some motor in its preproduction model stage has been analyzed and the more satisfied results obtained. |
