*3.8. The Assessment of Compatible Economic Use (Model Ahp1)*

The compatible economic use is the possible compromise between the profit of economic use and the conservation status of the historic building.

The villas considered in this part of the work are three villas managed by the Fondazione Ville Vesuviane (see above), because they are already planned for new use (two are museums, and one hosts the municipal library) and represent a significative subset of the Vesuvian Villas system.

The compatible economic use is valued from a group of parameters useful for the analysis of the current uses of buildings, their economic aspect and their general contribution to the conservation of the structure.

All these actions are necessary for the calibration of the reference model, to which will be made the calculations based on the villas chosen as case study.

The parameters used are (see Figure 6)
