This study investigates the technological process of heating a liquid considered as a controlled cybernetic system for converting resources into a usable technological result. The work aims to solve a pressing task of choosing a single universal criterion for assessing the effectiveness of technological processes. The subject of research is the ELF (Normalized Efficiency Criterion) computing module, designed for an integral assessment of the effectiveness of cybernetic control over technological processes in discrete time.
This work reports designing a computing module that converts technological input parameters and corresponding price coefficients into a system of cost indicators of costs and useful effect. The proposed system allows for the reduction of heterogeneous resources and the result of the process to a single scale, which makes it possible to formalize their joint analysis and a coordinated comparison of alternative modes. Elementary cost functions and aggregated indicators of the control cycle are introduced, on the basis of which the first-level integral accumulators are formed – accumulated costs and accumulated effect.
To assess the efficiency of control over a given time interval, secondary integrators of the second level and the mode selection index are used, which reflects the excess of the integral effect over the integral costs in the inertial-accumulator sense. Within the framework of the approach, the additional benefit and resource intensity of the permissible control mode are determined, which are formed using a storage device with a reset mechanism in the case of violation of the regime conditions.
The permissibility of the mode is set by the threshold rule and the procedure for resetting the final indicators in the case of its inadmissibility, which provides a diagnostically interpreted separation of the causes of zero efficiency. The proposed structure of the computing module focuses on the analysis, diagnostics, and optimization of control modes and allows for software implementation as part of cybernetic control systems
