3.6.2.2. Multi-Indicator Changes
In order to investigate potential possibility to have several change of
indicators in the same time interval It is of interest to demonstrate a number of
cases with the different internal relation among the indicator changes. It is
anticipated to have following options with the relation among the indicator
change as shown in table 2.

3.6.3. Resilience Index Monitoring and Processing
Beside the demonstration of resilience index by the specific values of
indicator and multi-indicators it is of interest to investigate online monitoring
of indicators and their processing into the time dependent resilience index. As
the method for the agglomeration multi-indicator it is anticipated to have
monitoring structure as the measurement of individual indicator within the
time scale for every individual events and formation of the resilience index for
every event.
With the agglomeration of the resilience index for individual indicators
the total resilience is obtained as linear function of the of the individual
resilience indices. In this respect we can write
