ecological perspectives thought from the other perspectives they have various significance.
Therefore, it is considered that the efficiency of energy production technologies life cycle
depends on the rationality of its stages as well as on the ability to satisfy the needs of the
interested parties and the rational character of the micro, meso and macro environment
conditions.
Formalized presentation of the multiple criteria analysis (see Table 8) shows how changes
in the micro, meso and macro environment and the extent to which the goals pursued by
various interested parties are satisfied cause corresponding changes in the value and
utility degree of diferent energy production technologies. With this in mind, it is possible
to solve the problem of optimisation concerning satisfaction of the needs at reasonable
expenditures. This requires the analysis of energy production technologies versions
allowing to find an optimal combination of different interested parties goals pursued,
micro, meso and macro environment conditions and finances available. (Sliogeriene et al.,
2009).
The ESIAPVN-DS system gives comprehensive information about the quantitative effect on
the value by the environmental factors of energy companies: the system analyses the effect
of each criterion separately. For example, a click on any selected criteria value in its cell
(links AVG, MN) within the matrix of alternatives (menu item “Descriptions of the
alternatives”) activates automatic assessment and the system offers a recommendation to
increase the company's value by changing the criterion respectively (Fig. 8).
