| Abstract: |
| In this paper, based on conventional importance analysis of FTA, we present a new importance analysis of FTA where each elementary event's probability is considered as fuzzy number after the introduction to extension principle in fuzzy mathematics. Finally, an example is given. |
| Keywords: fault tree analysis(FTA), fuzzy importance analysis, fuzzy number |
