Reliability Analysis of the High-Voltage Power Battery System Based on the Polymorphic Fuzzy Fault Tree

Table 1

Correspondence between language variables and the fuzzy probability.

Serial number	Fuzzy language	Semantic symbols	Triangular fuzzy number
1	Very high	VH	(0.9, 1.0, 1.0)
2	High	H	(0.7, 0.9, 1.0)
3	Generally high	GH	(0.5, 0.7, 0.9)
4	Medium	M	(0.3, 0.5, 0.7)
5	Generally low	GL	(0.1, 0.3, 0.5)
6	Low	L	(0, 0.1, 0.3)
7	Very low	VL	(0, 0, 0.1)
