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.
The information controlling model transport system during transient conditions
(Institute of Electrical and Electronics Engineers, Inc., USA, 2019) Pihnastyi, O. M.; Kozhevnikov, G. K.; Bondarenko, Tetiana
This article is devoted to designing an information management system for the conveyor line of mining enterprises. The analytical design method for the transient mode of the stepped speed control system of the conveyor line was developed. The partial differential equation was used in constructing the conveyor line model. The description of the production system is fulfilled in the single step approximation. A decision was obtained which determines the state of the parameters of the production line for a technological position specified as a function of time. Has been determined the length of the transition period during which the initial condition for the distribution of labour objects along the conveyor affects the parameters of the state of the conveyor line. The method for calculating the current parameters of a conveyor line with the use of partial differential equations allows the design of control systems for production lines of conveyor type for transient modes. The originality of the results obtained is to improve the PDE-models of the conveyor-type production systems used to design highly efficient production control systems operating in transient modes.
The kinetic model of the production line
(Місто, 2017) Pihnastyi, O. M.; Korsun, R. O.
The paper discusses methods of constructing the kinetic equation of the technology process. The article presents a model of the interaction of objects of labour with technological equipment, which is the basis for the derivation of the kinetic equation. To describe the state of the production line introduced numerical characteristics.
About the methods of formalization of technological process
(Брама, 2016) Tubychko, K. V.; Pihnastyi, O. M.
There are mass, serial and single types of production are determined by the coefficient of consolidation of operations at the workplace (GOST 3.1121.84). Mass production is characterized by a type of highly specialized departments and sections on output, limited and stable for a long period of the time range of products. The main objective of planning is to ensure the movement of workpieces on at a given pace of operations. A significant part of the calendar-planned regulations for the type of mass production is sustainable and just laid the basis for the planned regulations of the production lines. Planning is based on the calculation of the rate of release and details of the calculation of interoperable standards groundwork. When a batch type production nomenclature of manufactured products less stable, but still regularly repeated in the release program, the number performed in detail shops operations far exceeds the number of jobs that determines the production of goods parties. Main planning task in batch production, ensuring periodicity of manufacture products in accordance with the scheduled task. Increasing seriality achieved the unification of parts and typed processes. The objective of production planning is to manufacture products on time and uniform loading of production sites for a given production cycle. Each type of production of different methods can be arranged. The main ones are in-line, single party and methods of production. The most effective line method. The set of methods, tools, and principles of organization of the process to form the production planning and control system. Specifically shown what it takes to build a mathematical model of operations.
