Towards the ecotourism: a decision support model for the assessment of sustainability of mountain huts in the Alps.

This paper studies mountain hut infrastructure in the Alps as an important element of ecotourism in the Alpine region.

The methodology is based on qualitative multi-attribute modelling supported by the DEXi software.
