line wires. This ice formation will have adverse effect on the power
transmission. There is potential development of the ice layer. The change of
the thickness ice layer leads to the increase the weight of the ice which may
cause fracture of the power line. In the design of the power line special
precautions is made to preserve safety of the power lines. In this respect the
design of power line include the maximum thickness as of the ice layer as the
limit to prevent eventual catastrophic events.

Change of Power Consumption
The change of power consumption is an immanent problem for any high
voltage transmission line. There is possibility to have sudden increase of the
power demand in some urban regions leading to the potential critical state of
the power transmission. It is of interest to notify that the change in power
consumption and its maximum value may result in the catastrophic event.
e.
Change in Human Behaviours
The social aspect of the potential sudden change of the electric power
consumption may lead to the diverse reaction of the human behaviour. In
particular, the prediction of the human behaviours is important issue which
may lead to the catastrophic events. The human dwellings are designed with
the respective communication space in order to make possible human
movement within the dwelling under a severe power shortage. In the situation
when it happen there is a need for mass communication.
In this exercise a following cases are taken into a consideration:
CASE 1- EC > IL = IC = PC = HB
Case 1 represent situation when the priority is given to the Change of
Energy Cost indicator with other indicators having the same value. It is of
interest to notice that if the priority given to the Change of Electricity Cost
Indicator the result prove that the relation among the option under
consideration the electricity option is having the highest value of the resilience
Index with Investment Cost, Ice Layer, Power Consumption and Human
Behaviour following.
CASE 2- IC > EC = IL = PC = HB
