Application of fuzzy fault tree analysis on burning and blasting of LPG tank

It shows probabilities of each basic event for burning and blasting of LPG tanks applying triangle fuzzy numerals. The distribution of probability for top event is calculated on the base of fault tree and fuzzy operators. Median method is applied to analyze fuzzy significance. Combined with sequence of each fuzzy significance, the major sequence of hidden danger and harmful factors for burning and blasting of LPG tanks is concluded. The relevant management means and guarding measures are put forward in order to eliminate danger or control serious extent of the accident.
