A Combined MAGDM-Based Framework Employing EDAS and CRITIC Techniques for Green Building Technology Schemes Evaluation

The urbanization process in China is rapidly developing, and the scale and development speed of urban area buildings are astonishing. The development of green buildings aims to provide people with a comfortable and healthy living space with minimal resource consumption, achieve harmonious development of the building economy, resources, and environment, and enable them to follow a sustainable development path. When designing green buildings, multiple specialties should be combined, and various technical professions such as architecture, structure, water, heating, and electricity should cooperate and explore together. The green building technology schemes evaluation could be treated as a multiple attribute group decision making (MAGDM) problem. Recently, the EDAS and CRITIC technique was employed to implement MAGDM. Spherical fuzzy sets (SFSs) could express the uncertainty in MAGDM more effectively. In this paper, a novel spherical fuzzy number EDAS (SFN-EDAS) technique based on SFN cosine similarity measure (SFNCSM) and SFN Euclid distance (SFNED) is implemented for managing the MAGDM. Moreover, the CRITIC technique is extended to SFSs to implement the attribute weights based on SFNCSM and SFNED. Finally, SFN-EDAS technique is employed for green building technology schemes evaluation and some comparations to further demonstrate the SFN-EDAS technique.
