**8. Conclusions**

Any plan for the physical reuse and functional adaptation of cultural heritage must necessarily find a balance between market demands, the cultural and social significance of the heritage to be revitalized, and the community's aspirations, respecting the identity of the asset and its urban context. In this decision-making context, this research presented a multi-level integrated methodology that supports the preliminary assessment of complex decisions [71] according to a multi-methodological approach aimed to facilitate a more informed decision-making process. The methodology was applied to a pilot project for the adaptive reuse of cultural heritage, specifically a group of mountain huts in the village of Lorica located in the Sila National Park (Italy).

The methodology, used in the preliminary stages of the project, integrated different tools and utilized various techniques from the field of economic estimation. The combination of integrated, qualitative, and quantitative methodologies, according a multi-phase approach [71], provided effective support to the Decision-Makers (DMs), guaranteeing objectivity in choices and transparent negotiation among the various stakeholders involved in the valorization and reuse of the cultural heritage [72] according to a transparent and rational framework for identifying shared solutions and intervention priorities.

The methodological framework provided support to DMs in defining priorities for intervention and actions based on a multidimensional and multi-criteria assessment for the definition of the most favorable alternative scenario, which was also verified from the point of view of its feasibility and sustainability. The adoption of this structured multi-methodological and integrated evaluation process offers valuable opportunities, particularly in economically vulnerable contexts such as the case study, where effective allocation of scarce resource is fundamental for the conservation of places and communities.

Integrated multi-methodological approaches are widely utilized in addressing complex decision-making problems across various domains of knowledge in accordance with the 2030 SDGs and European quality principles [73,74]. Their application proves particularly beneficial when making decisions regarding the adaptive reuse of cultural heritage, whether in the public or private sectors. These decisions involve a complex interplay between values and diverse, often conflicting interests, necessitating the establishment of a shared platform among Decision Makers (DMs), stakeholders, and the community [75,76] to define reuse projects conceived with the perspective of economic development in the relevant territory [76–79].

The model applied to the pilot project demonstrates the effectiveness of a transparent and comprehensible evaluative process that allows for a rapid assessment of the financial feasibility of the project using a Financial Feasibility Plan (FFP) and performance indicators based on the Discounted Cash Flow Analysis (DCFA). The evaluation process is thus an integral part of the project development process, serving as a support in the initial stages of assessing investment feasibility, optimizing investment choices, and facilitating the efficient allocation of public resources. The developed model focuses on "steady-state" cash flows. This simplification allows for the early identification of collective needs and any potential technical, procedural, and economic-management obstacles.

On the basis of the developed management hypotheses developed in the FFP, it is evident that the preliminary assessments of the economic and financial feasibility of the RD accommodation activity planned within the renovated cabins were thoroughly verified. The municipal administration, with this investment of general interest, committed to revitalize an abandoned hamlet with positive benefits for the entire community [80].

The results obtained from the application to the pilot project highlight the potential of a user-friendly and easily replicable model, even for less-experienced users. This model can be implemented as an additional verification of the evaluation criteria generated from more complex financial analyses.

Based on this application, it is possible to outline some future research paths. Firstly, the implementation of the model will be replicated in other pilot areas to increase its reliability. Secondly, a dynamic SWOT analysis [81] will be utilized in the model to provide more efficient support in structuring the decision problem with guidelines and strategic recommendations. Thirdly, through a more in-depth stakeholder analysis and sensitivity analysis for criteria elicitation, it will be possible to visualize different scenarios to test the robustness of the results in selecting the most favorable alternative.

In conclusion, it can be stated that the combination of different evaluation tools is highly promising in defining a framework that assists DMs in both the public and private sectors involved in the redevelopment and reuse of cultural heritage. This combination is also promising in the strategic evaluation of procedures to renew the vision of plans, programs, and projects for the enhancement of unused cultural heritage landscapes [82–84].
