The meaning and role of parameters in the equations.

ParameterMeaning and role

RPMThe resilience performance metric of the road network
nThe number of all nodes in the network
iA node in the network, V is a set of nodes, i ∈ V [1,…,n], i is usually as the origin
jA node in the network, V is a set of nodes, j ∈ V [1,…,n], j is usually as the destination
Ii
PiThe average number of reliable independent pathways considering pathway importance between node i and any other (n-1) nodes in the network
K (i,j)The total number of independent pathways between node i and node j
kCounting the number of independent pathways
Pk (i,j)The kth independent pathway named connected by each link l in series between node i and node j
