• Green supplier selection

For many companies, the selection of green suppliers has become a key strategic consideration due to regulatory requirements and market trends. In this paper, an extended qualitative flexible multiple (QUALIFLEX) method is used to solve problems regarding the selection of green suppliers using probability hesitant fuzzy information. First, a new Hausdorff distance between two probability hesitant fuzzy elements (PHFEs) is introduced, and the properties of the proposed distance are discussed. Second, a likelihood measurement for PHFEs is proposed based on the new Hausdorff distance; moreover, an extended QUALIFLEX is developed based on the likelihood measurement. Finally, the practicality and effectiveness of the proposed method is tested using a green supplier selection example; furthermore, a comparative analysis using probability hesitant fuzzy information is also performed.
