3.5.6. Discussion
Resilience Index as the measure of potential ability of energy system to
recover after changes introduced by the respective indicator change. In this
demonstration exercise, four indicators are used in the evaluation of the
system. In designing specific cases it is anticipated individual cases with single
indicator change equal zero and other indicator changes are as specified in the
table 2 .
Results obtained by this analysis are presented as the agglomerated
indicators reflecting constrains introduced for every case. It is of interest to
notice specific cases.
Case 1 is reflecting a situation which imposes zero Economic Indicator
Change and other indicators are having values as specified in table 2.
Regarding obtained results for this case it reveals the agglomerated indicator
rating with the priority to the Option 4 -Social Indicator Change with other
options rated as shown in table 2 for this case. It is of interest to notice that this
case is designed with the aim to show the effect of economic indicator change
on the ability to avoid, minimize, withstand, and recover from the effects of
adversity, whether natural or man-made, under all circumstances of use on the
system under consideration.
Case 2 describe situation when Environment indicator is taken with the
zero value change and other indicator changes are specified with numerical
values corresponding to values as specified in table 3. Results obtained for this
case are presented in the rating of agglomerated indicator of Options under
consideration. As it can be noticed the obtained results are not substantial
different in comparison with Case 1. The Resilience Index rating for this Case
is different in the position of Option A on the rating List.
Case 3 shows a substantial change in the rating list among options. Even
Option- Social Change is on the first place on the rating list the position of
other options is changed. Option B is moved on the second place of the List
and Option C has exchanged position on the List. The Resilience Index change
is result of the strong effect of social change on the energy system.
Case 4 shows the effect of the technological change on the Resilience
Index. This means that the introduction of technology on the ability of energy
system to withstand fluctuation of social parameters on the energy system
behavior. It is obvious that there are potentially different effects on the
resilience of energy system..
