The analysis of the level of development of industry digitalization in Industry 3.0 has shown that the main methodology of the formation of production management systems is recognized by the methodology of software and target management, which is the basis for the developed ODAS draft. The basic method of automated control systems modeling in Industry 3.0 is the method of forming a structured hierarchy. In the beginning, a hierarchy of goals is formed, and then the hierarchy of the organizational system is determined in the following identical forms of representation, namely: tasks; ranks; operations. Such an approach provides for the definition of the composition and content of operations that need to be implemented in management. The main problem of the hierarchical approach in the methodology of programmatic planning and management is the problem of forming the goal of the activity. In this approach, there is no requirement for the formation of an integral (general) purpose of the activity in the explicit form and hierarchy of goals. Simultaneously with the method of software-targeted management, the method of an architectural approach to the structuring of the system of production control dialogue was developed. The main advantage of this approach is that the architecture of the structural graph of the system does not depend on the organizational structure of the investigated organization. On this basis, a five-level structural graph of the control system was formed. For each level of management, the functional structure of the deciding system is formed. The crucial point is that the developed architecture of the functional structure of the deciding system is universal for all five layers of management and has the appropriate mathematical justification. The fundamental difference between this approach is that in the architecture of the decisive system, the model of the control object for the corresponding level is used. The structural representation of the software-target management and the functional representation in the architectural approach are integral parts of the integrated representation of the enterprise. It is the architecture of the functional structure of the control system for the layer Δ corresponding to the architecture of the intelligent control system. It follows that the development of intelligent production management systems for Industry 4.0 is not possible outside the theory of intellectual systems, which in turn is based on the theory of functional systems.
