Abstract
Purpose. The article aims to develop a concept of creating a basic architectural solution for the problems of synthesizing the structure of a functional system. Methodology. The research methods are based on systems analysis methods. Findings. The research proves that a production facility will have the maximum degrees of freedom (the possibility to achieve maximum efficiency) if its structure is presented as a packaged functional system. In this setting, the technological part of the packaged system consists of a converting mechanism with a simple basic function, and a storage mechanism. Originality. The paper describes the operation cybernetic model that takes into account quantitative parameters of input and output products of the operation, technological mechanism wear and tear and cost-time estimation of the products. The functional dependences of energy consumption and technological mechanism wear and tear on changes of energy supply intensity are presented. The generalized cybernetic model of the operation has been examined. Also it is shown that the technological object has maximum degrees of freedom, i.e. maximum efficiency. Graphs of changes in quantitative parameters of the generalized technological operation model and cost indicators for input and output products of operation have been constructed. The profitable control range has been determined as a range where the operation output products cost is more than the operation input products cost. The operation model of directly coupled technological mechanisms of a converting class has been investigated. It has been calculated that the added value losses for coupled mechanisms are 57 %. It has been found that the range of acceptable controls of the technological object is substantially smaller than control ranges for objects of its structure. Practical value. The technological mechanism of a converting class is proposed to interact with a storage mechanism only. This allows extending the control range due to maximum degrees of freedom in the industrial object. This can be possible only if its structure is presented as a package functional system. And the technological part of the package system has to consist of a converting mechanism with a simple basic function and a storage mechanism. The approach provides an increase in control optimization. It is planned to make a synthesis of the functional system structure and identify a range of effective controls in the next research.
