Документ On the methods of the statistical theory of control system of production lines(Національний технічний інститут "Харківський політехнічний інститут", 2015) Azarenkov, N. A.; Pihnastyi, O. M.; Khodusov, V. D.The analysis of modern methods of organization and management of production is given.Документ Conceptual positions statistical modeling of production processes. Building PDE-models(Національний технічний інститут "Харківський політехнічний інститут", 2014) Pihnastyi, O. M.; Krasovskykh, KarinaIn work formulated the concept of statistical modeling of technological processes of production and technical systems. In conformity with this concept, the state macroparameters of the technological process are determined by the state microparameters a large number of objects of labor, distributed in interoperation reserves on the technological route. It is shown that at a sufficiently large number of objects of labor located in interoperation reserves along the technological route, appear special type laws characterizing state macroparameters of the technological process. The characters of these laws do not depend on the behavior of microparameters which determine the state of an individual item of work. Although the with increasing amounts the objects of labor unimaginable increases complexity and intricacy of relations which determine the state macroparameters of the technological process, however, at that appear the peculiar laws which on no account can not be reduced to the laws of behavior of an individual element of a macroscopic system.Документ Entropy method in the models industrial process control(Національний технічний інститут "Харківський політехнічний інститут", 2013) Azarenkov, N. A.; Pihnastyi, O. M.; Khodusov, V. D.For the first time, the importance of the entropy method in control theory has Dzh. Fon Neumann. Entropy approach to modeling the processes discussed in detail B. N. Petrov, I. V. Prangishvili. The entropy of the process is associated with the distribution function of process parameters on the possible states. The distribution function of the items of work is not explicitly linked to the parameters describing the state of the items of work in the technological processing.Документ Statistical theory of management manufacturing process(Національний технічний інститут "Харківський політехнічний інститут", 2013) Pihnastyi, O. M.The report formulated the theoretical basis for building a statistical model of process control. According to the concept of statistical modeling of the macro parameters of the process is determined by the state of the objects of labor. Objects of labor are distributed along the production route. It is demonstrated that a sufficiently large number of items of work appear Speciality patterns characterize the state macro parameters of the process. The nature of these laws do not depend on the behavior microparameters of an individual item of work.Документ Thermodynamical analogies in the problems of stability of socio-economic systems functioning and optimal control(Фізико-технічний інститут низьких температур ім. Б. І. Вєркіна НАН України, 2006) Demutskiy, V. P.; Pihnastyi, O. M.Thermodynamical analogies in the problems of stability of socio-economic systems functioning and optimal control are considered.Документ To a question on application of the statistical theory for the description of industrial systems(2009) Khodusov, V. D.; Pihnastyi, O. M.The application of the methods of Statistical Physics for its description is possible owing to the representation of the manufacturing firm with mass production output as a system with a large number of elements (the basic products) of stochastic nature, which is in the production process. The behavior of the basic products along the technological chain depends on the definite manufacturing and technological laws in accordance with the technological process of the manufacturing firm, its production plan, the availability of manpower resources and equipment. The state of the production system’s basic products at any instant of time is given as the point in two-dimensional phase space. The function of the basic product’s distribution in the rate of expense’s variation is set and the equation similar to the kinetic equation in Physics is written down. The engineer-production function, which is analogous to the force moving the basic product along the technological chain of the production process, is set and can be determined from the technical documentation of the manufactured article approved in the manufacturing firm. The producer function, which describes the interaction of the basic products (the system’s elements) during their moving along the technological chain of the production process with technical equipment, is based on the equipment disposition schemes and its technical characteristics according to the operating mode of half-finished products. Using the kinetic equation a closed system of balances equations is written down in a zero approximation on a small parameter for the moments of the distribution function. The system of balances equations describes the behavior of the basic economic macroscopic quantities of the production system, such as reserve, pace, and dispersion of the production output along the technological chain. From the balances, equations were obtained the well-known relations in business operation theory for the calculation of reserves and places of the production output.
