To this end, the Fuzzy Analytic Network Process (FANP) method was applied to identify and prioritize the key factors influencing construction waste management. The model seeks to identify existing barriers and challenges in managing construction waste and to propose strategies for optimizing the processes of waste reduction, material reuse, and recycling. The findings of this research indicate that among the various criteria, the incompatibility of transportation equipment with the type and quantity of materials had the most significant impact on waste management across project components. In addition, other critical sub-criteria such as insufficient awareness of designers regarding the project's execution details, lack of adequate practical experience among designers, and misalignment between material procurement and stakeholder expectations were also identified as influential factors in optimal waste management. These results demonstrate that design and execution decisions play a crucial role in minimizing construction waste, and that precise planning can contribute to cost reduction and environmental impact mitigation. The proposed model can serve as a framework for policymakers and construction project implementers, enabling them to adopt efficient policies and make informed decisions at various stages of the project. Ultimately, the model aims to support better construction waste management practices and promote sustainable building initiatives.</p> https://journalrmde.com/index.php/jrmde/article/download/118/207
