AHPSortll-GAIA: A Sorting Method in Model Engineering to Sort Cities According to the Risk of Sustainable

Model engineering is conducive to decision makers by describing and solving problems in a reasonable way. Various sorting methods have been widely used in the field of model engineering, however, they are rarely visualized and clearly presented to decision makers. In this paper, in order to sort cities in China according to their sustainable development risks and visualize the result by representing it on a two dimensional plane, a novel method combined with AHPSortII and GAIA(graphical analysis for interactive aid) has been proposed, which can visualize and solve the multi-criteria sorting problems with less pairwise comparisons. The proposed method can help decision makers have a clearer understanding of the result obtained by the sorting method and make better decisions. Finally, a case study is provided to illustrate validity of the proposed method.
