Conservation and management of architectural heritage is gaining importance in the context of responsible development and environmental awareness. The integration of Heritage Building Information Management (HBIM) and Multi-Criteria Decision-Making (MCDM) is capable of addressing the challenges of heritage preservation decision-making. HBIM, tailored to historic structures, serves as a digital repository of geometric and semantic data of any kind related to these buildings, while MCDM provides a structured framework for decision-making, considering technical and subjective aspects. This research proposal aims to optimize heritage preservation decision-making processes by identifying possible decisions, designing user-oriented workflows, and integrating them into a cohesive framework. This approach seeks to foster collaboration, provide practical guidelines, and contribute to effective informed decision-making by all stakeholders involved in heritage management. Despite limitations, the research proposal has the potential to improve the effective integration of decision-making processes in the management of heritage structures.
