models, which, in turn, return results which become the input data for yet other
models. The decision support system EGT-PH-DSS enables processing of large
amounts of data and monitoring of changes of all criteria in question. The system
may be supplemented with new objects and data about them. A significant
advantage is that the system displays the intermediate results, which reflect the
impact of each criterion on the utility and value. The decision support system
EGTAV-DSS is available online at the address

. The

Use of the EGT-PH-DSS is simple, but the system performs a thorough analysis
and presents a lot of useful information. The system's advantage is the analysis of
the weights of all criteria used in research. The weights of criteria are analysed in
the module's window ''Results of multiple-criteria evaluation of the alternatives''.
A click on the value of any selected criterion in a matrix cell on the links AVG,
MN displays the value of each selected criterion in percentage compared to the
same criterion of other objects (see Fig.
8
). The result also shows the increase in
the percentage that would raise the value of the object in question. The same
screen of the model can display the effect of environmental factors determined
