Abstract: Highlights•An optimization method is proposed to determine the crisp attribute weights in IFAHP.•The improved IFAHP can avoid information loss caused by defuzzification.•A visual analytics approach is proposed to present the decision-making process.•UMAP and Voronoi diagram are combined to guide DM to select the best choice visually.
