The total Resilience Index is an additive function of all resilience
Indexes as
follows
The resilience index is composed of sub-indicators. In the same way the
economic,
environmental, technological and social resilience element could be
obtained, as follows. Under the
assumption that the sudden indicator change
resumes is a linear function of time, then we can write
