4.5. Results
This section presents two different types of results showing different aspects of the decision process. For a clear visualization of the results, only n = 7 control options, obtained by varying the aquaculture area from 1300 to 1450 ha with step 25 ha, are initially evaluated and compared. The presented results are obtained by varying the criteria weights for fixed external factors in order to show the ability of the DSS to model the preferences and the objectives of end-users. Then, for fixed criteria weights, different value assignments to external factors are considered in order to show how uncertainty is managed in the proposed DSS. The aim is to select a control option that is robust with respect to varying climate conditions. At the end of this section, it is also shown how to exploit the feedback branch in Fig. 1 in order to refine the solution provided by a previous DSS iteration.
