alternative;

The main advantage of the EGTAV-DSS, which distinguishes it among other
decision support systems, is recommendations to user. The model analyses all
alternatives using the entire set of criteria. The system automatically analyses each
criterion, determines its effect, compares it among alternatives and assesses its
potential to change the end result in the assessment of alternatives. The system
calculates the level of influence each criterion can have on the priority and utility
of an object and provides visual recommendations (Sliogeriene et al.
2009
).
The recommender model selects and displays three most significant criteria,
which determine the utility of each alternative in question (see Fig.

).
The decision support system for assessment of energy generation technologies
EGT-PH-DSS facilitates the decision-maker to extract from its database versatile
and thorough quantitative and qualitative information about the effect of envi-
ronment and to use the model base for flexible analysis of these factors and for
decision-making. The EGT-PH-DSS provides logical and informative results about
the utility of the technologies in question and the effect of environmental factors
on their value; it also gives recommendations for each criterion and helps avoid
errors and partiality. In summary, the developed decision support system EGT-PH-
DSS enables unbiased results, which can be used in assessment of a range of
