Abstract
To solve the problem of energy efficiency of modern enterprise it is necessary to reduce energy consumption. One of the possible ways is proposed in this research. A multi-level hierarchical system for energy efficiency management of the enterprise is designed, it is based on the modular principle providing rapid modernization. The novelty of the work is the development of new and improvement of the existing methods and models, in particular: 1) models for dynamic analysis of IT tools for data acquisition and processing (DAAP) in multilevel energy management systems, which are based on Petri nets; 2) method of synthesis of DAAP tools in energy efficiency management information systems (EEMIS) of the enterprise which provides a reduction in hardware and time costs from 10% to 40%; 3) method of conflict-free data exchange determining the minimum memory speed for the synthesis of real-time exchanges, it reduces the cost and energy consumption; 4) method of calculating the signal of postsynaptic excitation of neural elements decreases the processing time of technological data two or more times. The proposed methods, models and tools have been tested while implementing the EEMIS of the intelligent mini-greenhouse, as a result, energy efficiency has increased by 12%–25% (depending on season and peculiarities of growing plants).
Highlights
Nowadays we are witnessing a large-scale introduction of new technologies to industrial production [1,2,3,4,5,6,7] in the developed countries of the world (Industry 4.0) [8]
The main parameter of the study is the efficiency of synthesis process which depends on the number of parameters of the system under development
The indicators of energy efficiency of mini greenhouse may vary because they depend on season of the year, weather, peculiarities of certain plants growing, etc
Summary
Nowadays we are witnessing a large-scale introduction of new technologies to industrial production [1,2,3,4,5,6,7] in the developed countries of the world (Industry 4.0) [8]. Several standards have been developed for the construction, deployment and analysis of management systems in modern enterprises. These include the popular ANSI/ISA-95 standards [9,10] and IEC 62264 [11] standard which is based on the ISA-95. CMC, 2022, vol., no.2 development of the energy sector of Ukraine is impossible without the introduction of Industry 4.0 technology and implementation of the existing standards ANSI/ISA-95, IEC 62264, etc. The urgent task today is to develop the IT for a multi-level energy efficiency management of the enterprise, which will take into account the peculiarities and specifics of the energy sector of Ukraine
