The choice problem of the urban performances to support the Pachino's redevelopment plan

The historic centres, by using a large sustainability concept, should be the places where the quality and the symbolic values may prevail on the quantitative and functional ones, but often, the poor resources and the low quality of the management do not allow to promote a sustainable retraining process for them. The plan decision makers should verify the impact of the technical choices and then the sustainability of the actions, but also the impact of the planning policies on the economic performance and then on the economic sustainability of these actions. Therefore they must be helped to identify the planning actions, their funds and the value system they want to promote. In this regard, this study proposes a model to support the management of the retraining plan for Pachino’s historic centre. The proposed model is a DSS that is developed using the MAUT and the IMO-DRSA tool
