The article deals with the issue of developing a cyber-physical system of a psychological profile of a specialist in professions of the ‘man-nature’ type in the formation of specialists for sustainable development. The proposed cyber-physical system of psychophysiological support of professional self-realization in professions of the ‘man-nature’ type is presented in the form of a hierarchical structure, the upper level of which reflects the vision of the customer (client) and contains the necessary properties and their significance coefficients, and the lower level is a set of characteristics that affect the corresponding properties as well as the corresponding weight values. The cyber-physical system makes it possible to clearly represent the psychophysiological profile of a specialist when working on building a standard of a specialist using the method of expert assessments. This system also allows you to easily automate the process of creating a reference model of a specialist for professions of the ‘man-nature’ type and will provide estimates of the significance of each of the obtained characteristics. The novelty of the cyber-physical system lies in the integration of points of view on the professional self-realization of a specialist on the part of the customer and on the part of psychologists. The significance of the upper-level elements comes from experts (customers) for each profile, while the weights of the relationship between characteristics and a certain quality are constant regardless of the specialty and can be obtained from expert psychologists in advance. Based on the analysis of a formalized description of available psychodiagnostic techniques, a generalized model of psychodiagnostic techniques and a structural model of a set of psychodiagnostic techniques have been developed. This approach differs from the known ones in a formalized representation, as well as taking into account the vector of resources necessary for the implementation of the technique. The proposed approach made it possible for the first time to formulate the problem of choosing a set of psychodiagnostic techniques as an optimization problem. The developed complex of algorithms, containing all the characteristics of cybernetic systems, is controllable and consists of a set of subsystems that act as mechanisms for the restoration and implementation of self-preserving reactions. That is, this complex of algorithms is effective, which is characterized by a certain set of parameters. Hence, the key role of the system of transmission and processing of information in training specialists for sustainable development becomes clear, and the importance of intellectualization of management processes is explained.
