resumes starting state is linear function of time, than we can write

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

Resilience index is formed by the Sustainability Index expressed as the
linear function of quality indicators multiplied with respective weighting
coefficients. Sustainability Index composition reflects the quality indicators of
the system under consideration. Its integral value in time scale after sudden
change is the stability merits of the system. If it is assumed that the
Sustainability Index change of individual indicators can be approximated with
linear function then the change of indicator multiplied by the time increment
for return to the starting value is the Resilience Index and is measure of the
stability of the system. Also, with numerical integration of indicators in the
time scale Resilience Index can be obtained in the real time scale of the
system.
