Introduction. The lack of a coherent systemology law does not enable the use of evidence-based formalization to solve the basic theoretical problems of law interpretation and enforcement. The development of an appropriate formal-theoretical apparatus is possible on the basis of a productive systemological concept. The justification of this concept is based on the study of philosophical bases and fundamental principles (integrity, dynamic equilibrium, feedback, etc.) and the use of logical and linguistic methods of problem-oriented system approach. Theoretical Basis. Methods. The conceptual and logical modeling of legal ergasystems, the systems analysis and resolution of the theory-applied base of technology of two-tier legal regulation; the synthesis and modification of private scientific results of the author published in 2000–2019, with copyright in the author’s scientific works and educational publications. Results. The contemporary conceptual variant of combined “ICS”-approach (“information, cybernetic and synergetic”) as a general methodology of analysis and optimization of legal ergasystems, as characterized by the following conditions: the substantiation of the appropriate three-part set of methodological research principles, corresponding to the triple-aspect physical nature of the study of complex legal systems as ergasystems; the clarification of the conceptual and logical model of the legal ergasystem taking into account the fundamental feedback principle; the definition of the law of necessary diversity of William R. Ashby is justified and corresponding conditions of realize of effective technology of two-level (normative and individual) legal regulation; the definition of basic concepts and methodological principles of modern systemology of legal regulation; the justification of the functional organization of the Invariant Rational Control Loop. Discussion and Conclusion. A developed conceptual object-oriented version of combined “ICS”-approach for analysis and optimization of legal ergasystems is a methodological basis for the development of a working formal-theoretical apparatus of legal regulation systemology. This will formalize the decisions of the main theoretical problems of law interpretation and enforcement, as well as developing and implementing special information and legal technologies based on the concept of information and functional databases and knowledge. This will in turn ensure the information increases the effectiveness of the system of legal regulation of public relations as an information and cybernetic system subject to the subjective organizing process of human activity and the objective synergetic processes of disorganization.
