Context. Consideration of comprehensively studied object in the form “system – environment” to obtain an approximate accurate real situation reflection. Objective. Search for solutions to problematic research issues based on the entropy approach for systems “object – environment” of different nature and complexity, studying them and obtaining knowledge (stable information) and providing them as a set of complex system tasks modulated by different entropy functions. Method. The following criteria are used to assess the sustainability of the development of a system object: integrity – the failure of the trajectory of development of the object at a certain forecast time interval from a set of safe states; monotony of growth of indicators of development of object on a certain time interval with the subsequent preservation of them in the set intervals of admissible values; compliance of the development trajectory with the target changes according to the requirements of safety and sustainable development, resistance to disturbance, including asymptotic stability of the program trajectory and structural stability of the system. In the conditions of nonlinear development of events and spontaneity of processes “object – external systems” at stable structure of system object of research it is expedient to apply the entropic approach and knowledge from the field of the theory of stability developed for technical and cybernetic systems. Results. The proposed entropy approach to analysis is determined by the fact that the object is characterized from the standpoint of compliance with acceptable regulatory constraints and processes regarding the acceptability of the object of the external environment or the possibility of resolving the situation of coexistence “object – environment”. Within the analysis of a system object, this means that for both stationary and dynamic conditions, their state is described by a certain function, the changes of which indicate the approach to a certain point of homeostatic relations with the environment. The practical application of the provided methodological proposal for finding solutions in conditions of uncertainty of a certain kind is considered on the example of determining measures to influence the course of positive development of the child’s body in the situation of diagnosis of cerebral palsy in the form of information and software application at realization of the appointments of medical character applied to them (factors of influence of emergency). Conclusions. The proposed entropy approach to the choice of decision-making problems for determining the state and changes as a result of process transformations in system objects of the type “studied system – environment” in conditions of uncertainty does not require additional conditions characteristic of known estimates by criteria in common mathematical means of decision making.

“…The unstable systems state leads to crises that are conventionally equated with qualitative transformations in them. Thus, the study of modern complex systems is becoming relevant in the processing of information data in accordance with the standard system approach and the latest methods of information theory [3].…”

“…Under the research object study or development in accordance with the general definition of J. Clare [1] is understood part of the world, which for a given period of time is a unit that reflects the natural (ecological), economic and social aspects of life. The object interacts with environment, which is central to the investigated integrity [3] (as opposed to existing approaches in solving complex system problems, because it is the basis of the functionality of the object).…”

In article is determined of object state in researching ”system – environment” based on system analytic-graph modeling for representation real relationships and relations between any systems in nature. Justiﬁed non-standard solution according to forecasting states and changes results in ”system – environment” based on constructed cognitive models and entropy analysis for action direction sustainability and implemented situations assessment. Practical usage of systematic methodological support for complex objects comprehensive research based on graph models sequential analysis. To analyze physical processes displacements between simple ideal system components, which are sources of potential and kinetic energy, changes in its capacity through matter or energy accumulation, is used structural graph – physical processes topological model.

In the article substantiated the expediency of introducing the basics of systemological analysis in modeling and structuring of studies of complex objects, which allows to establish conditions for the implementation of a certain target function, which is responsible for the state and functionality of the investigated object in certain conditions of the environment, taking into account the macrostate of the complex system, through experiments of microstates, and its changes in the system “object – the environment” regarding the state of external systems using an entropy func-tion according to a consistent analysis of uncertainties and their solution to establish conditions for the stabilization of the object or achieve the goal of regulation situations based on information synergetics. It was concluded that, proposed comprehensive entropy-synergy analysis of the determination of the state “the investigated system – the environment” and changes in the consequence of process transformations in systemic objects in conditions of certain uncertainty does not require additional research, characteristic of known estimates for the criteria in widespread mathematical means decision-making.
