This study aims to examine a hierarchical framework for sustainable consumption (SC) for cruise ships and identify the causal relationships and decisive attributes of cruise ship operation practices that allow cruise organizations to achieve a higher level of sustainable performance.,This study applies a hybrid of the Delphi method and a fuzzy decision-making trial and evaluation laboratory (DEMATEL). DEMATEL methodology helps to construct complex causal relations through digraphs, which depict interrelationships among attributes. The fuzzy set theory assesses experts’ perceptions of attributes given in linguistic preferences. The Delphi method has been previously used to validate attributes and determine the validity and reliability of the construct from qualitative information.,A set of three aspects containing 21 criteria were defined based on previous literature and expert consultations. The analysis results show that waste minimization and recycling and recovery are causal aspects that influence efficient resource use. Emission controls on ships, cruise ship alternative energy sources, ballast water treatment systems, water purification systems and nanofiltration systems are also prominent criteria for the improvement of SC during cruise ship operation.,This study contributes to the literature by offering a hierarchical framework for SC literature and confirming the role of this issue in improving the cruise industry sustainability. In practice, as such results provide key attributes for successful performance, the implications are offered for companies developing new activities, either in ensuring compliance with business goals or in decreasing the environmental impact.

评估游轮上的可持续消费做法

这项研究旨在研究游轮可持续消费(SC)的分层框架,并确定游轮运营实践的因果关系和决定性属性,以使游轮组织实现更高水平的可持续绩效。 Delphi方法和模糊决策试验与评估实验室(DEMATEL)。DEMATEL方法论有助于通过有向图来构建复杂的因果关系,而有向图描述了属性之间的相互关系。模糊集理论评估专家对语言偏好所赋予属性的看法。Delphi方法先前已用于验证属性,并根据定性信息确定结构的有效性和可靠性。根据先前的文献和专家咨询,确定了包含21个标准的三个方面。分析结果表明,废物的最小化,再循环和回收是影响有效利用资源的因果关系。船舶排放控制,游轮替代能源,压载水处理系统,净水系统和纳滤系统也是改善游轮运营过程中SC的重要标准。该研究通过提供SC的分层框架为文献做出了贡献文献,并确认此问题在改善邮轮业可持续性中的作用。实际上,由于此类结果为成功绩效提供了关键属性,因此对开展新活动的公司具有一定的意义,
