Abstract
In this paper, we introduce “fuzzy Voronoi” diagrams for fuzzy numbers of dimension two (FNDT) by extension of crisp Voronoi diagrams for fuzzy numbers. The fuzzy Voronoi sites are defined as fuzzy numbers of dimension two. All the operations are defined in FNDT framework. We propose an analytical approach to compute the boundaries of fuzzy Voronoi diagram for pyramidal-shape FNDT.
