Analysis of Rule Refinement Conflicts

Hans-Werner Kelbassa

Thereexists no methodical standard for conflict analysis in the selection of optimal rule refinements. Current rule base refinement systems select the best rule refinements out of a set of competing ones by using heuristics rather than exact optimization procedures. In order to come up with an Operations Research approach to the optimal refinement of rule bases, an analysis of rule refinement conflicts is carried out by discussing a well defined example with three generic refinement classes. The conclusion is that the introduction of a binary relation, termed ONE-OF DISJUNCTION, enables to apply a linear binary Operations Research approach to the optimal selection of rule refinement heuristics.
