natural or man-made, under all circumstances of use on the system under
consideration.
Case 2 describes a situation where the Environment indicator is taken with
zero value change and other indicator changes are specified with numerical
values as shown in table 3. Results obtained for this case are presented as 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
i
n the first place
i
n the rating list the position of
other options is changed. Option B is moved
i
n the second place of the List
and Option C has exchanged position on the List. The Resilience Index change
is a
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 the introduction of technology on the ability of an 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 the
energy system.

ONCLUSIONS
Resilience Index as the parameter of an energy system, is the
quantification of the elasticity of the system. If the instant change of a single
parameter is introduced, it leads to the Resilience Index defined with the
exponential time change. Multi-indicators changes require a respective
definition of the Resilience Index, which include agglomerated indicator as the
measuring resilience parameter of the system.
The Resilience Index of an energy system expressed in the form of
agglomerated indicators, gives the opportunity to assess a complex system
complied with potential malfunction of the energy system. It is of special
interest to learn about the relation among the indicators leading to the
degradation of the energy system. In this respect, the behaviour of an energy
system is vulnerable with the complex degradation.
It is of interest to establish an appropriate methodology for the energy
system resilience measurement as a tool for the quantitative verification of the
system. In particular, there is a need for the resilience quantification as a safety
