Abstract: | In the domain of environmental protection, multi-criteria evaluation is used in cases where multiple alternatives, on the
bases of multiple parameters, need to be evaluated. Depending on the particular goal of investigation, various approaches
have been developed and applied. This various multi-criteria approaches differ in parameter weighting method, in data normalization
method as well as in the method for assessment of alternatives. According to the applied multi-criteria methodology, the result,
i.e., the rank of alternatives may differ to some extent. In this context, parameter weighting bears special significance
in multi-criteria evaluation, while the choice of method is crucial for final result. The specificity of parameter weighting
process in environment protection is directly related to pronounced interdisciplinary character of this area, as well as the
large number of influential parameters. With this in mind, this paper presents an approach to multi-criteria evaluation which—through
integration of three specific methods for parameter weighting—allows more flexible and multi-purpose application. Based on
the established concept, a software application was developed. Besides automated parameter weighting, it also provides graphical
interpretation of results. The developed approach and software have been verified on the case study related to evaluation
of environmental loadings at six locations in the city of Novi Sad. |
