Case 3 includes preference to be given to income per capita priority. It can
be noticed that Option D is taking first place on the rating list. Options B, C,
and D ar e with increasing number of option. This proves that Income per
capita indicator priority does not substantial effect the stability of the system,

Case 4 reflects the situation when priority is given to Energy Consumption
Indicator. Int can be noticed that Case 4 is having the same rating list as the
Case 1. Even indicators under consideration in this case are different the
stability of the system is similar to the Case 2. This imply that stability of the
system under consideration is the same.
