SUMMARY
The aim of the paper is to provide support to an evaluation in urban planning, creating a useful approach for the choice of future alternative Operational Plans in Cava De’ Tirreni (Salerno). They represent planning tools that are usually formed after public announcements to select the interventions to be implemented in the areas of transformation identified by the general Municipal Urban Plan. A suitable system of territorial indicators to verify the achievement of such goals is also taken into account. With reference to three different urban areas, the evaluation has been carried out by Multi-Criteria Decision Aid (MCDA), using the PROMETHEE (Preference Ranking Organisational Method for Enrichment Evaluation) multi-criteria method and GAIA (Graphical Analysis for Interactive Aid) tool.
