In order determine specific value of the Resilience Index for the individual
cases following options are taken into a consideration. The design of options is
based on the on the priority given to the change of individual indicators. Each
option is defined with maximum change of specific indicator and changes
other indicators are introduced as specified in table 1.

The first step in this analysis is normalization of the data which will
include definition of the cases to be analyzed. It will imply the definition of
priority the weighting coefficients for each case. Following cases will be taken
into a consideration:
Case 1 Electricity Cost Change = Energy Production = Environment
Indicator
Case 2 Electricity Cost Change > Energy Production = Environment
Indicator
Case 3 Energy Production >Electricity Cost Change = Environment
Indicator
Case 4 Environment Indicator > Electricity Cost Change = Energy
Production
