The utility degrees and the revised market values calculated for the objects in question using
this method depend, directly and proportionally, on an adequate criteria system, weights of
the criteria and values of the weights.
If energy objects must be analysed or technologies selected, economic information and
economic valuation approaches are insufficient to ensure objectivity. Multiple criteria
analysis facilitates processing of extensive quantitative and qualitative information,
analysing of a range of external value-affecting factors and assessing of energy production
technologies with different dimensions in view of the most significant factors. Comparisons
of the utility degrees based on the defining quantitative criteria alone would hardly be
comprehensive and reliable in case of energy production technologies.
The utility degree and the market value of the object, project or technology in question may
be measured using the following sequence (Fig. 2):
1. Building a grouped decision-making matrix for multiple criteria analysis of the objects in question
2. Calculating the weights of quantitative and qualitative criteria based on an integrated assessment of
their positive and negative features
3. Determining the weights and priorities of objects
4. Adding the matrix values for each alternative with minimum as optimum
5. Calculating the utility degrees of objects
6. Identifying the value of the object in question
7. Revision of the identified value
8. Revision of the identified value

2.1 Methods for identification of criteria values and weights
It is expedient to make an integrated analysis of objects by combining quantitative and
qualitative assessment. Multiple criteria analysis methods are the right tool: they allow a
more thorough look at an object through combined quantitative and qualitative criteria; they
help to make an analysis by integrating both technical data and the results obtained using
economic valuation approaches or analyses. The so-called weighting methodologies that help
to determine criteria weights are one of the methods to determine preferences, and to make
quantitative and qualitative assessment of the weights attributed by people to some criteria,
which are then used to make decisions on implementation of a certain instrument. These
methods encompass a wide range of surveys, which help to approximate the quantitative
expression of social values, and a wide range of indirect valuation approaches, in which
significant factors are identified through debates in task forces or between stakeholders by
