Abstract This paper has reviewed a selection of Sonin’s models, each of which offers a perspective on the development of applied mathematics and decision-making tools. His research, centered around seven key models, illustrates a consistent effort to frame complex problems in ways that are both theoretically grounded and practically relevant. These contributions serve as examples of how mathematical modeling can inform and support real-world decision processes. The models discussed here form the core of the present paper.
