MCDM Selection of Laptops in TOPSIS: Criteria Weighting with Combined AHP and Entropy

This paper presents a combined approach based on the Analytical Hierarchy Process(AHP) with criteria structured in blocks and objective weighting of criteria with Entropy for improving the methodology of Multi-Criteria Decision Making (MCDM) for selecting laptop computers. A structured approach allows optimizing the combination of professional experts ' opinions and objectivity of data-driven entropy methods. The hybrid method is applied on a real dataset of 11 evaluation criteria and 12 alternatives from 4 major manufacturers of personal computers (PC) with a simulation reflecting the needs of individual users and small education organizations under conditions of COVID-19.
