Theses within this research project have analyzed different decision support methods in relation to the development of the new regulation policy. Raisa Hannus’s thesis describes a three-stage procedure which supports the Environmental Impact Assessment process and was tested students. Some of the findings were that in value tree analysis some preference elicitations were difficult and that compromise solutions are likely to gain more support than the extreme alternatives. New decision alternatives were generated using the Joint Gains software based on the method of improving directions developed in Systems Analysis Laboratory. The method performed well in this testing. Susanna Alaja’s thesis focused on human judgment biases related to decision problem structuring. It was found that the splitting bias could not be totally avoided even if the decision makers were trainee to avoid it before the prioritization.

The project emphasizes developing decision support on the practical level using the newest multiobjective models and the possibilities provided by the Internet. This area is desribed and discussed in general in the review paper by Hämäläinen et.al. Jyri Mustajoki, developed Web-HIPRE (the first internet based decision analysis software) for interactive weighting. In addition, there is a general purpose internet based Opinions-Online program for survey's and the comparison of alternatives by using web voting and prioritization.

Virpi Junttila’s thesis and the ISMO program applies dynamic multiobjective optimization to the generation of the feasible regulation policies. This is both methodologically new and important for problems related to lakes and rivers which almost always are intrinsically dynamic. The manuscript by Hämäläinen and Mäntysaari describes the dynamic interval goal programming approach used in ISMO program.
