The construction of a recommendation system for selecting one of five non-medication-based rehabilitation complexes for participants in armed conflicts and emergencies is described. Rehabilitation techniques developed at the Tomsk Science Research Institute of Balneology and Physiotherapy prevent potential chronicization of pathological processes, increase the body’s adaptive reserves, and improve quality of life in those affected by emergencies. A set of features was determined for each complex, providing the most precise identification of each complex. The principle underlying the construction of the recommendation system is instrumental in nature and the system could be used not only in rehabilitation and treatment centers, but also in other healthcare institutions.
