... As a result, the number of classifications at different stations is small and the acceptability index of different classifications varies greatly. This means that the proposed method can easily obtain a classification of the alternatives (Liu et al. 2022). In addition, the comparison of the two classification results for each metro station shows that more than 80% of the metro station categories remain unchanged. ...

... Owing to the complex relationship among the social and institutional systems as well as the economics of water use, the competition may aggravate ecological water shortage when multiple sectors use limited water resources (Yang et al. 2020). It is recognized that water resource can become either the obstacle of development or the driving force of economic growth (Du et al. 2022). In order to alleviate the regional water crisis, analyzing the relationship between the economy and the environment (more specifically between the production sectors and water consumption) can help policymakers and stakeholders to formulate scientific water management policies (Nie et al. 2021). ...
