This work presents a decision support system (DSS) enhancing users to effectively integrate classical purchasing portfolio approaches with additional strategic oriented priorities and information in order to effectively support the definition of purchasing directions and action plans.
With these aims, a fuzzy-based DSS is designed and implemented. The decision process gets inputs from the Kraljic (K) matrix and draws directives on the traditional Olsen-Ellram (O-E) portfolio model integrating additional information about the purchasing context to validate their feasibility and suitability. The fuzzy DSS is applied to a demonstrative case study of an American multinational company operating in the field of Electric Power Systems and Alternative Energy Systems.
