Abstract: Multi-criteria analysis can represent the point of connection for a total engineering of the building sector, which, in particular in relation to the phase of management of the built environment, still suffers from little acknowledgement on the implementation of different maintenance strategies. This is due, at the same degree, to the lack of solid knowledge on the modalities of performance decay, and to the lack of execution of in-depth analysis before the decision of a maintenance strategy.

In this paper, considering a component, plaster covering, for which the performance decay has been analyzed during a study on 100 buildings, some possibilities of application of multi-criteria decision methods (TOPSIS, WSM, WPM, VIKOR), together with their validation thanks to the partial similarities of the results, are presented.

Four different maintenance strategies are analyzed, and four different management scenarios are simulated as a function of the priority attributed to the criteria of evaluation.

Key words: maintenance, multi-criteria, TOPSIS, VIKOR
