An integrative approach to water treatment technology selection

Making decisions about river pollution control and management is a complex problem. It is difficult because of its scale, requisite coordination of multiple models and the requirement to generate multiple scenarios through modifying assumptions, preferences, and direct and indirect changes of parameter values. Such a DSS can be used to interpret a decision maker´s general strategic inputs and to decompose these into specific instructions that can be used to access databases, engineering and decision models. A simple example illustrates a prototype that implements the methodology for part of the decision process
