Mathematical methods and models have been used for a long time for efficiency analysis and managerial performance of complex socio-economic systems. The Data Envelopment Analysis (DEA) appeared as a generalization of simple efficiency ratios over the multidimensional case. In this approach, every production unit is described as a set of input and output indicators. From a mathematical point of view, this means that the multidimensional production possibility set emerged in the multidimensional space. Free Disposal Hull (FDH) models appeared almost simultaneously with the DEA models. However, constraints of the FDH models are non-convex what significantly hold back the development of this approach. Many papers were devoted to the computation of important characteristics of models. However, some works noted the absence of papers in the world literature devoted to methods for frontier visualization in FDH models. In this paper, we develop an algorithm for three-dimensional frontiers visualization in FDH models.
