Web-HIPRE: multiattribute decision support system as a useful tool for water resources management

The analysis of different scenarios for improving water quality of the Jeziorsko reservoir is presented. This artificial reservoir plays various functions, for example it is an important element of the flood control system in Poland; water from the reservoir is used for industrial and agricultural purposes, etc. This means that the control and management of water resources in this area are very complex. Web-HIPRE (HIerarchical PREference analysis on the World Wide Web) is a multiattribute decision support system which provides a set of analytical methods (e.g. analytic hierarchy process, multiattribute value theory, etc.), to support decision makers in the evaluation of different alternatives. The system described in this paper was applied to evaluate the effects of different program measures, which were proposed to improve the ecological status of the Jeziorsko water body. Using the Web-HIPRE system, the “Warta River Basin Project” was analysed in order to obtain the best scenarios for achieving objectives described in the EU Water Framework Directive.
