The article analyzes the results of the methodology of object research and construction of its mathematical model, provided that the object is considered as a holistic set of components that have a special connection with the environment and are a subsystem of a higher order system. An effective tool of the outlined principle is system analysis. The research methods proposed in this paper are a mathematical model that contains interconnected heterogeneous resources, the operation of which is subject to a set of rules and objectives for information and communication infrastructure of the enterprise, its socio - economic development and effective organization of business processes. The aim is to determine the methodology of object research and build its mathematical model, provided that the object is considered as a holistic set of components that have a special connection with the external environment and are a subsystem of a higher order system. An effective tool of the outlined principle is system analysis. systems analysis is a problem-solving methodology based on system structuring and quantitative comparison of alternatives. Thus, the system analysis will logically combine a set of theoretical, empirical provisions of the subject areas of natural and economic sciences, the practice of developing complex systems that provide scientific validity for solving a particular problem. Scientific and methodological approaches to economic and mathematical modeling and evaluation of management decisions effectiveness at an industrial enterprise are identified. To build a set of interconnected economic and mathematical models, as well as any individual model, requires a set of principles that allow the correct process of formalization of modeling systems and objects. One of the main principles of modeling economic processes is the principle of systematization, which contains the research methodology of the object and construction of its mathematical model, provided that the object is considered as a whole set of components that have a special connection with the external environment order. The effective tool of the outlined principle is the system analysis, which consists of models development coordinating management decisions at the industrial enterprise. Key words: methodology of object research, model of organizational and communication mechanism, mathematical model.
