identifying the utility degree of alternatives, which shows the percentage at which one
alternative is either better or worse than other alternatives in question;
identifying the priority of alternatives;
identifying the market value of alternatives in question;
integrating classic valuation approaches based on economic indicators in the analysis.
The environmental studies performed by the authors were used as a basis to build the
Decision Support System for Measurement of the Effect by the Environmental Factors on the
Value of Energy Companies; the system, after more thorough studies and corrections, may
be suggested for use in the energy sector as a tool helping to validate diverse decisions, to
analyse and select energy production technologies.
In multiple criteria analysis methods, energy production technologies, or the companies
which use such technologies, must be assessed considering quantitative (operational
territory, number and length of engineering infrastructure objects, technical and technological
parameters, economic indicators) and qualitative (condition, degree of modernisation and
new technologies, environment protection, political, legal and legislative restrictions) criteria
of the current market conjuncture, which describe the object, as well as other indicators that
affect the value. When the key factors that may affect the result of the problem in question
are selected, it is time to build the set of criteria and to determine weights of environmental
indicators pertaining to the object in question.
When we have to assess alternatives in the energy sector, and to determine their efficiency,
analysis focuses on a variety of energy production technologies, which differ both by their
qualitative and quantitative parameters; the method of integrated analysis, however, allows
to separate the factors that affect value, to determine the evaluation criteria, and thus to
compare such technologies, to calculate their utility degrees, to make a priority line and to
calculate the revised market value. The method of integrated analysis includes the following
main steps:
1. Identification and description of qualitative and quantitative criteria that affect
activities of a technological complex for energy production;
2. Building of an integrated database based on the description of the objects in question;
3. Use of multiple criteria analysis methods as a means to determine the utility degree and
to revise the market value of the alternatives.
When the objects are already described in both quantitative and conceptual forms, an
integrated database must be built to describe in detail internal and external factors that
affect the value of the objects in question. The database is a basis for multi-variant designing
and multiple criteria analysis of the objects. Even though the amounts of available data and
information are huge, handling of a multiple criteria analysis problem is made considerably
easier by using automated intelligent decision support systems designed in view of the
selected goals.
4.2.1 Building of criteria systems
In order to assess the macro, meso and microenvironment factors that affect the utility
degree, and the revised market value of the technological facilities for energy production, as
well as in order to compare the objects, a system of defining criteria must be built. The
system is built so that it helps to analyse the environment of the selected technological
facilities together with economic and technical indicators pertaining to the objects. We
divide the system of criteria into two main groups: qualitative criteria and quantitative
criteria. The groups are then subdivided into subsystems, which may, in turn, be subdivided
further:
