PreC--The tool

The executable specification we talked about constitutes the core inference-engine of the prototypical tool PreC (i.e., Preference Cruncher). This tool is aimed at assisting the user in interactively dealing with (partial) preference orders and qualitative uncertainty. Figure 1 depicts the main window of PreC, through which the user can describe, manage, and modify his assessments. Figure 2 and Figure 3 display the dialogs to input/edit events and constraints. The visualization of preference orders in form of graphs (cf., Figure 4) allows the user to modify or extend the set of events, for instance in preparation of the execution of one of the inference tasks.
