可持续航空燃料（SAF）为全球航空脱碳提供了一个可行的选择。与传统的喷气燃料不同，SAF可以在几个生产途径中生产，这使得它们的选择成为一个具有冲突目标的复杂多标准决策（MCDM）问题。在本文中，我们提出了一个多准则为基础的框架来评估SAF生产途径，这是一个顺序的决策过程与反馈调整机制。鉴于SAF技术发展的早期阶段以及此类技术的数据稀缺，在这项研究中，我们邀请了各种航空业利益相关者协助收集数据和偏好。我们的MCDM框架旨在通用，为潜在用户提供灵活性，以便为相关利益相关者选择适当的实施决策。拟议框架的优势在于其灵活性，以适应不同利益相关者的主观判断，排名方法的选择，以及结果的稳健性。我们在利益相关者参与的方法中使用我们的MCDM框架，根据社会，环境，经济和技术影响类别下的24个标准对11种SAF生产途径进行排序。我们的分析表明，环境和经济影响类别是最重要的，其次是技术和社会标准;气化/费托（F-T）为基础的生产工艺优于发酵和石油为基础的;和废气是首选的原料沿着与木渣。这些发现为决策者提供了选择SAF生产途径的指导方针。
Sustainable aviation fuels (SAF) provide a viable option to decarbonise global aviation. Unlike conventional jetfuel, SAFs can be produced in several production pathways making their selection a complex multi-criteria decision making (MCDM) problem with conflicting objectives. In this paper, we propose a multicriteria based framework for evaluating SAF production pathways, which is a sequential decision-making process with feedback adjustment mechanisms. Given the early stage of SAF technologies' development and the scarcity of data on such technologies, in this research, we involved a variety of aviation industry stakeholders to assist with data and preference gathering. Our MCDM framework is designed to be generic to provide flexibilities to potential users in choosing the appropriate implementation decisions for the relevant stakeholders. The strength of the proposed framework lays in its flexibility to accommodate various stakeholders' subjective judgements, choice of ranking method, and robustness of results. We used our MCDM framework within a stakeholders' participatory approach to rank order 11 SAF production pathways against 24 criteria grouped under social, environmental, economic, and technical impact categories. Our analysis revealed that the environmental and the economic impact categories are the most important ones followed by the technical and the social criteria; the gasification/FischerTropsch (F-T) based production processes are preferred over fermentation and oil-based ones; and waste gases are the preferred feedstock along with wood-residue. These findings provide decision-makers with guidelines on the selection of SAF production pathways.
