Abstract

Alternative design solutions of buildings can be successfully evaluated applying Multiple Criteria Decision Making (MCDM) methods. There are a lot of methods available for supporting complex decisions in construction. However, previous research works show that various MCDM methods can produce different ranking results. Accordingly, three criteria of optimality, namely WSM (Weighted Sum Model), WPM (Weighted Product Model) and joint method of the latters called WASPAS (Weighted Aggregated Sum Product ASsessment) are applied, and their peculiarities are examined by comparing to well-known and reputed MOORA (Multiple Objective Optimisation on the basis of Ratio Analysis) method. A case study of ranking the facades for public and commercial buildings is presented.
