<jats:p>In this paper we propose a combined AHP-IBA model for selecting the best SAP
consultant for an SAP ERP project. The goal of the SAP Project Manager is to
choose the best consultant, the one who is able to implement standard SAP
functionalities with quality and on time. When making a decision on the basis
of multiple criteria, the traditional Analytic Hierarchy Process (AHP) method
does not take into account the fact that attributes may correlate, assuming
that there are no dependencies between them. However, the dependencies of the
attributes can often be used to model important knowledge for multiple
criteria decision analysis. We propose an extension to the traditional AHP
method by applying Interpolative realization of Boolean algebra (IBA), using
AHP to determine the criteria weights, and IBA to model the logical
interactions among criteria. The research conducted on ERP consultant
selection suggests that the decision making process is modelled more
accurately if logical interactions between attributes are modelled before
applying AHP.</jats:p>
