Sustainability of hydrogen supply chain. Part II: Prioritizing and classifying the sustainability of hydrogen supply chains based on the combination of extension theory and AHP

•Extension theory and AHP are combined for sustainability assessment.•Multiple stakeholders are allowed to participate in the decision-making.•Twenty eight criteria are considered and quantified using fuzzy variables.•The sustainable level of hydrogen supply chain could be identified.

The purpose of this study is to develop a method for prioritizing and classifying the sustainability of hydrogen supply chains and assist decision-making for the stakeholders/decision-makers. Multiple criteria for sustainability assessment of hydrogen supply chains are considered and multiple decision-makers are allowed to participate in the decision-making using linguistic terms. In this study, extension theory and analytic hierarchy process are combined to rate the sustainability of hydrogen supply chains. The sustainability of hydrogen supply chains could be identified according to the synthesis correlation degrees to each classical domain. Finally, an illustrative case is studied by the proposed method, and the results show that the proposed method is feasible for prioritizing and classifying the sustainability of hydrogen supply chains.
