Abstract
This research presents an algorithm for the assessment of deterioration risks and the planning of preventive conservation actions. The proposed system is based on systematic collection and analysis of key parameters, including the type of support, conservation history, restoration techniques, environmental conditions and other factors that may influence the material stability of Cultural Heritage over time. The methodological approach involves several phases: data collection, risk factor analysis, assignment of reference values to each significant variable and graphic visualization of conservation status and associated risk level through chromatic gradients. The algorithm enables the calculation of an overall risk score through a weighted evaluation system that integrates mathematical equations with a scoring approach reflecting the relative importance of each parameter. Currently implemented as an Excel®-based application, the system is designed to be accessible to restorers and conservation professionals in interoperability with integrated advanced digital ecosystems/Information systems (BIM/HBIM-CAD and VPL). Visual parametric representation facilitates communication of complex information. As a dynamic and scenario-driven tool, the algorithm requires regular updates to maintain its effectiveness across varying environmental and conservation contexts. The algorithm has been tested on a sample of artworks restored and monitored over the past five years, including significant works by Titian, Lorenzo Lotto and Luca Giordano. These case studies, museum collections, historic interiors and open-air monuments, have allowed for the verification of the system's ability to detect vulnerabilities and support tailored preventive conservation strategies. All data, analyses, and results are systematically recorded and managed within a dedicated information framework to ensure traceability and continuity of conservation management. The experimental application has confirmed the validity of the structured data-driven approach in identifying critical issues, prioritizing conservation actions and supporting informed decision-making.
