This criterion may definitely be improved and the improvement may be achieved by efforts
of CEOs and politicians.
The developed ESIAPVN-DS system ensures informative and unbiased results, which may
be used in assessment of diverse energy objects aiming to determine their utility and the
efficiency of their environment, but in other types of analysis as well. This system is
experimental and not used for practical applications, because it needs further improvement
and enhancement of individual functions, as well as continuity of studies. The current
version of the system, however, may be used as an extra method or tool to control the
reliability of results in a range of studies or analyses. The system, after further
improvements, may be a useful tool in analyses dealing with the impact of environmental
factors on the value, utility, and performance of objects, in identification of the vital values
of environmental factors, and as an aid to plan the potential activities, to choose
development scenarios, and to assess technologies. The ESIAPVN-DS system uses the set of
criteria describing the environmental factors and the criteria weights and thus may analyse a
variety of companies operating in the sector, may accumulate the data and use it later in
analyses of other objects. In analysis of the development trends of the energy sector, in
selection of alternatives, or in measuring of the utility degrees of individual energy
production technologies, the main research interest is selection of the criteria and building of
a system of universal criteria for the sector's analysis. Important aspects are choice of
adequate criteria significant in the sector, finding the relation between criteria of various
levels, and assessment of their weights. Then it would be possible to make the decision
support systems for the analysis of the sector more universal, and to expand their
application.
5. Conclusions
In the energy sector, decisions encompass interrelated solutions at various levels: selection
of development scenarios in the energy sector; decisions on implementation of political
instruments; or decisions on the choice of specific technologies for energy production in the
future, and on promotion and implementation of specific energy projects. The analysis of
alternative decisions made at different levels demands for relevant criteria for the
assessment of such alternatives, as well as for indicators to be used in quantitative and
qualitative evaluation of the alternatives. The methods based on multiple criteria analysis
are promising when one has to analyse the energy sector and energy production
technologies. Moreover, these methods have advantages over the traditional analysis
methods based on economic data. The multiple criteria methods have tools that help to
consider the full set of environmental factors of the object, and to integrate significant
economic indicators. They also eliminate the bias of analysts and ground the assumptions
on a comprehensive market analysis.
The experts assessed the impact on the value by environmental factors and their assessment
suggests that the experience of CEOs, readiness to introduce innovations, environmental
factors, and corporate social responsibility are important factors that affect the activities of
the selected objects operating in the sector in question. The effect of these factors on
operating decisions and the value of objects may only be assessed using innovative methods
based on mathematical analysis, for example, multiple criteria complex proportional method
for measurement of the utility degree and the market value.
