Stage 3. Input of the expert assessment data into the ESIAPVN-DS system for data
processing;
Stage 4. The system's model bases are used to process the data: the programme compiles a
matrix of normalised weighted criteria expressed in numbers, and determines the revised
market value, priority and utility of the objects;
Stage 5. The ESIAPVN-DS system's recommender model analyses the results: the system
gives the values of the criteria that affect the value, and automatically prepares and suggests
recommendations on ways to reduce or increase the impact of certain criteria and thus to
increase the market value of the object.
The ESIAPVN-DS system is available online at the address < http://iti.vgtu.lt/elektra/> . In the
main page of the ESIAPVN-DS system, the system's administrator or a user may log in and
fill in the main data tables (Fig. 6). The figure shows the expert assessment results of the
energy objects selected for our analysis (Kruonis Pumped-storage Hydroelectric Power
Plant, Kaunas Hydroelectric Power Plant, the Lithuanian Power Plant and the experimental
geothermal power plant).

criteria that affect energy companies
The system automatically processes the data and, upon clicking on relevant links, shows the
results of multiple criteria evaluation of the objects. The system automatically solves the
multiple criteria task: performs multiple criteria analysis of the selected objects, measures
their utility degree and market value and thoroughly analyses the impact of the criteria on
