Integrating multi-dimensional decision-making and quorum valuation for sustainability assessment of the cruise industry

Abstract

Recently, sustainability has been an essential aspect of the cruise industry, and academics and professionals are evaluating its sustainable development based on environmental, economic, and social dimensions. However, most previous studies have not considered the interactions between the dimensions in the analysis process. To address this gap, this study proposes a model for evaluating the sustainable development of the cruise industry called MDDM-QV. This model integrates the Multidimensional Decision Making (MDDM) method and Quorum Valuation (QV) operator, which improves decision processes by providing measures of majority opinion and consensus. The model has been applied to the cruise industry in Málaga, which is one of the main cruise ports in the Mediterranean. The results show that the MDDM-QV integrated approach can be a robust method to provide strategies for the sustainable development of the cruise industry.
