Figure 26. Graphic presentation of Resilience Index.
In the processing of the resilience index components a following
simplification is introduced. The sudden change of the specific indicator from
the initial value will be recovered within the time period Δt
0
. Under the
assumption that the sudden indicator change resumes is a linear function of
time, then we can write

If it is assumed that the time interval for resuming starting state is equal for all
indicators than and then the Resilience Index for the individual case is
