“Dose-Response” Vulnerability Assessment of Urban Power Supply Network: Foundation for Its Sustainability and Resilience

Table 2

Minimum effective threshold of α on the functional performance ().

Event type		Scale of failed nodes
		5%	10%	15%	20%	25%
Intentional	Degree-based	α=0.2	α=0.3	—	—	—
	Betweenness-based	α=0	α=0	—	—	—
Random		α=0	α=0.1	—	—	—

Note: Table 2 focuses on the minimum threshold of α that can improve the functional performance to more than 0.5 (i.e., ); “—” means no α can meet the requirement.
