Tryoshnikov was an oceanologist, geographer, and researcher. He submitted his first scientific articles, as A. F. Treshnikov, in this scientific field to the
Reports of the Russian Academy of Sciences (DAN – Doklady Academii Nauk). In 1987, an initiative group of scientists engaged in interdisciplinary research of open dynamical systems. At first, the group consisted of four people: G.M. Degtyarev, A.G. Ivanov-Rostovtsev, L.G. Kolotilo and O.A. Lyubchenko. Several dozen specialists from various fields of natural sciences and humanities joined the work in different periods. The SELF model with applications was published in a series of articles of DAN, presented by academicians of the Russian Academy of Sciences: A.F. Treshnikov, V.I. Ilyichev,
K.Ya. Kondratiev, N.S. Solomenko, E.I. Shemyakin, S.L. Solovyov and others. Corresponding members of the Russian Academy of Sciences S.P. Kurdyumov, L.N. Rykunov and other scientists also participated in the D–SELF project. Expanded versions of the DAN articles have been published in various academic and applied publications. Some of these works have been translated into English and published abroad. D-SELF is a scientific field of interdisciplinary research of systems of various nature in self-organization and self–regulation. D-SELF is the initial abbreviation for a Double (dual) general process combining SELF-organization and SELF-regulation. ==Other activities==
