A SDSS for the Ex-Ante Evaluation of Investment Risk in the Real Estate Redevelopment Processes

Real estate redevelopment processes represent an important avenue for achieving sustainable development goals, but at the same time, they pose complex and opaque decision-making problems. Most existing risk assessment tools involve aggregate-scale analysis or require knowledge of extensive project financial data, which is often not yet available under ex-ante evaluation conditions. The aim of the work is to provide a tool that can support stakeholders to recognize high-risk Naples zones in terms of real estate risk investment. This is possible by defining a Spatial Decision Support System (SDSS) for ex-ante risk assessment model that allows to build a Spatial Real Estate Risk Index (ISRR). The proposed model adopts the flexibility of the AHP technique and the GIS system's abilities in order to provide a georeferenced thematic risk map for the OMI zones of Naples.
