Extending AHP with boolean consistent fuzzy logic and its application in web service selection

Abstract

When making a decision on the basis of multiple criteria the traditional AHP method does not take into account the fact that they may be interrelated. It is proposed that the traditional AHP method could be extended by applying fuzzy logic for aggregating the criteria into a single objective function. The application of consistent fuzzy logic is preferred since no conventional fuzzy set theory is in the Boolean frame. The basis of this approach is the Interpolative realization of Boolean algebra (IBA). The proposed approach is illustrated on the web service selection problem.
