Full textThesis for granting the Degree of Candidate of Economic Sciences in specialty 08.00.04 - economy and management of the enterprises (by types of economic activity). - National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2019. The thesis is devoted to actual problems of theoretical, methodical and practical aspects of management of energy efficiency of an industrial enterprise. In the dissertation the theoretical basis is investigated, a variety of formulations of concepts "energy efficiency", "energy saving", "energy management", "energy efficiency management" are considered and their use in work is determined. It is proposed to evaluate the energy efficiency of the enterprise by the indicator of energy intensity, which is the ratio of two economic values: the annual cost of energy resources to the cost of production. It is taken into account that the management of energy efficiency of an industrial enterprise is based on the general principles of the theory of control, according to which the control system consists of two subsystems - the managing one, and the controlled one, which is exposed to the control and has the effect (influence) of the control subsystem. Emphasis is placed on the fact that tasks and conditions formulated by higher hierarchical levels of energy efficiency management are a particularly important factor of influence. It is established that the task of improving the energy efficiency of industrial enterprises of the Ukrainian economy requires the creation of appropriate conditions at all levels of government. Such levels are: state, sectoral, regional and enterprise level. It has been established that conceptually levels of energy efficiency management systems can be represented as a hierarchical feedback loop. The conducted analysis of the regulatory framework in the field of energy efficiency and energy saving showed that at each stage of energy efficiency management specific tasks were defined for ensuring the process of implementation of state policy, with the nature of tasks for each of the levels having its own specificity. It was found that after the first world energy crisis, industrialized countries paid much attention to solving the problem of improving the energy efficiency of their economies and gained considerable experience in this direction, which was reflected in the international standard ISO 50001: 2011 "Energy Management Systems", which was further supplemented by a number of improving of the provisions in ISO 50001: 2018 "Energy management systems. Requirements and Guidelines for Implementation, "which implements PDCA Continuous Improvement Management. This standard should be implemented in the regulatory acts when implementing the "Energy Strategy of Ukraine to 2035". On the basis of the conducted analysis of the Laws of Ukraine on energy saving, international and national standards, the methodology of energy audit, it is established the expediency of introducing amendments to take into account the multiplicative and synergistic effects of saving energy resources in the modernization of energy equipment. The results of the analysis made it possible to correlate the level of ISO 50001 implementation by countries with the indicator of energy intensity, namely reducing it with the widespread introduction of energy management systems in industry, which allowed to reduce energy consumption per unit of production for the period 2000 - 2017 by almost 20%. Increasing GDP energy efficiency for Ukraine is a particularly important area of economic development. Significant investments are needed to improve energy efficiency, and the search for domestic investment sources is of particular importance for the country, for which it is desirable to have a toolkit for calculating the projected value of energy savings for the enterprise. It was found that the main levers for improving the energy efficiency of the leading countries were investment and improved governance. A significant increase in energy efficiency can be achieved by improving the management of energy efficiency of industrial enterprises; improving the energy efficiency of industrial enterprises, improving management and implementing the ISO 50001 standard. It is proposed and substantiated the feasibility of using the neural network method in the energy efficiency management of an industrial enterprise to determine the energy intensity index, which can be used for prompt provision of information on forecasted cost savings due to energy savings with multiple refinements in the process of determining the final values of the production form for the next year policies, setting up annual energy efficiency plans, planning other indicators production, on which the energy efficiency of an industrial enterprise depends. The methodical approach of determination of the index of energy intensity of the enterprise with the help of artificial neural networks (ANN), with the use of methods of expert estimations, a priori ranking and correlation-regression analysis is developed. An economic and mathematical model was created bas ed on a multilayer directional perceptron synthesized by the genetic algorithm method. The efficiency of the methodological approach was checked, as well as its testing according to the statistics of the leading Kharkiv enterprises. In the process of testing and analyzing its results, the conclusions were drawn about the need for: systematic accumulation of annual statistics, both the indicator itself and the factors that influence it; analysis of calculations and establishment of correctness of data accounting; identifying typical differences in the interpretation of a factor and making appropriate adjustments; taking into account the features of the enterprise; carrying out with the help of ANN research on the choice of rational values of production indicators - input values of the neural network that affect the indicator of energy intensity; studies on improving accuracy and forecasting due to changes in the structure and type of neural network, etc. Such a wide range of functions and the need for their systematic implementation led to the conclusion that it is advisable to create in the management structure of an industrial enterprise a structure that would include specialists capable of performing these functions - the Intelligent Energy Management Group (IEM). The practical result of the dissertation work on taking into account the multiplicative and synergistic effects is: first, the conclusion about the expediency of taking into account these effects when conducting an internal energy audit, for which it is necessary to make appropriate additions to its methodology of its conduct; secondly, the conclusion about the expediency of introducing into the legislative and regulatory acts the amendments that stimulate the enterprises to prioritize the modernization of power equipment with multiplicative and synergistic effect (as such, which provides significant savings of fuel and energy resources at the state level). Recommendations are given on the use of the results of work at different hierarchical levels of energy efficiency management and in other types of industrial enterprise management.

Full textMaster dissertation: 116 pp., 17 fig., 7 tab., 1 app., 53 sources. Topicality. The concept of data centers is embodied by many large corporations to provide access to a large number of users to certain resources. Effective management of the data center is connected with the need to solve a number of problems, first of all, creation of conditions for functioning of information and computing facilities of data centers, management of virtualized resources, maintenance of reliability and safety. By investing, hosting companies are hoping for profit and expecting a reduction in the cost of operating the data center, reducing the cost of customer service, which will eventually lay the foundation for effective business, both for the company itself and for customers. Ensuring the level of user requirements by minimizing costs is the essence of the problem of managing the functioning of the data center. Typically, this complex problem is divided into a number of smaller tasks, but not so much simpler. One of them is the task of resources and load management in datacenter. In this regard, it is important to develop a reinforcement learning algorithm [1] for managing virtualized resources that will help reduce power consumption and SLA violation time. Relationship of work with scientific programs, plans, themes. The research was carried out at the Department of Computer-Aided Management And Data Processing Systems of the National Technical University of Ukraine «Igor Sikorsky Kyiv Polytechnic Institute» within the theme «Development and implementation of an IT infrastructure management system with consolidated information and computing resources» (№ 0115U000322). The aim of the research is to improve the quality of virtualized cloud computing resources management by developing a management algorithm that reduces power consumption and SLA violation time. To achieve this goal, the following tasks must be performed: analyze the object environment of the virtualized data center resources management; review the methods of computing resources management; choose the simulation environment of data center; develop a data center model in a selected simulation environment; develop models of power consumption by physical servers; prepare data for simulating the dynamic load of virtual machines in data center; develop a modified reinforcement learning algorithm for managing the virtualized computing resources of data center; develop the software implementation of the reinforcement learning algorithm; make a research of developed algorithm effectiveness. The object of research is a process of virtualized computing resources management in data center. The subject of research is a methods and algorithms for virtualized computing resources management in data center. Research methods are methods of machine learning, which based on reinforcement learning. Scientific novelty of the obtained results. The possibility of reinforcement learning usage for of virtualized resources management of cloud data centers is analyzed. The method of dynamic placement of virtual machines on the basis of reinforcement learning is developed, which, when choosing controlling influences, takes into account power consumption and SLA violation time. An agent algorithm is developed which takes into account the changes in the workload on resources for deciding whether to turn on or switch to sleep mode of underutilized physical servers in order to reduce the cost of electricity. The proposed reinforcement learning agent is based on the Q-learning method [2], which allows determining approximation to optimal policy of controlling the modes of the physical server operation without prior load information.
