Journal Article 2021 04 16 In recent years, sustainable development and environmental protection have been receiving more attention in construction projects. Hence, the Green Road Construction (GRC) supplier selection problem is key for organizations to improve their environmental and economical performances. Accordingly, a new Hierarchical Group Decision (HGD) fuzzy ranking framework is presented based on Dynamic Interval-Valued Hesitant Fuzzy Numbers (DIVHFN) and the last aggregation approach to select the most appropriate GRC supplier. Thereby, DIVHFN theory and the last aggregation concept could decrease judgmental errors and data loss, respectively. Moreover, the weight of each criterion is obtained by proposing a new Dynamic Interval-Valued Hesitant Fuzzy Maximize Deviation From Ideal Decision (DIVHF-MDFID) method. Furthermore, the experts' weights are determined by presenting a Dynamic Interval-Valued Hesitant Fuzzy Preference Assessment (DIVHF-PA) method. Besides, to obtain precise weights, the opinions of experts are included in criteria/sub-criteria weight computations. Meanwhile, an actual case regarding the GRC supplier evaluation and selection problem for a construction project is provided to demonstrate the implementation process of the proposed approach. Finally, some comparative and sensitivity analyses are performed to confirm the validation and verification of the presented (DIVHF-HGD) approach. https://scientiairanica.sharif.edu/article_24254_66799b2bd0493647b88e462e59d53428.pdf
