In recent years, the industry's responsibility to join in sustainable manufacturing becomes huge, while innovating sustainability has been a new trend. Industrial enterprises are pursuing energy reduction to meet future needs for sustainable globalization and government legislations for green manufacturing. To run a manufacturing line in an energy-efficient manner, an energy-oriented maintenance methodology is developed. At the machine layer, the multi-attribute model (MAM) method is extended by modeling the energy attribute. Preventive maintenance (PM) intervals of each machine are dynamically scheduled according to the machine deterioration, maintenance effects, and environmental conditions. At the system layer, a novel energy saving window (ESW) policy is proposed to reduce energy for the whole line. Energy consumption interactivities, batch production characteristics, and system-layer maintenance opportunities are comprehensively considered. Real-time choice of PM adjustments is scheduled by comparing the energy savings of advanced PM and delayed PM. The results prove the energy reduction achieved by this MAM-ESW methodology. It effectively utilizes standby power, reduces energy consumption, avoids manufacturing breakdown, and decreases scheduling complexity. Furthermore, this energy-oriented maintenance framework can be applied not only in the automotive industry but also for a broader range of manufacturing domains such as the aerospace, semiconductor, and chemical industries.

BACKGROUND AND OBJECTIVES. Energy efficiency and energy saving are the priority direction of science, technology and engineering development in Ukraine. The policy of energy saving, carried out all over the world, is directed to all branches and scientific researches in all spheres. The big consumer of energy resources is the higher school. Updating of normative-legal and technical base aimed at design and operation of buildings with low energy consumption and high energy efficiency class shows the necessity of short-term solution of the problem. At the same time, there is a lack of a systemic view of energy efficiency, which does not allow evaluating the level of energy costs throughout the life cycle of higher education institutions, which shows the need to find effective solutions to the problem.METHODS. Multiple regression equation was used to assess the influence of factors on electricity consumption and energy efficiency of Kyiv National University of Technologies and Design, statistical analysis of the obtained data was performed.FINDINGS. As a result it was found out that the data of electricity consumption do not obey the law of normal distribution, so it is difficult to build an accurate prediction of electricity consumption. The use of HAB knowledge on energy efficiency allowed a more qualitative analysis and highlighted the main factors affecting electricity consumption. The university has unregulated central heating, individual air conditioning systems, and central and individual lighting. In this regard, we selected the following main factors: average outdoor air temperature, average duration of daylight hours, heating period, average number of people working per day, during the month to conduct energy monitoring and energy audit of university buildings.CONCLUSION. Implementation of suggested scheme of structural organization of typical system of automatic accounting of university energy consumption on the basis of university HUB of energy efficiency knowledge: server, allowing to collect, store and process data; routers by means of various wire and wireless communication technologies; hubs, installed on the objects of energy consumption; workstations, which are personal computers with installed software of used HUB will allow to optimize energy consumption.

В статье приводятся результаты экспериментов по измельчению отходов окорки ели в промышленном измельчителе Erdwich M600/1-400. В опытах использовали три группы влажности отходов: отходы непосредственно после окорки (относительная влажностью 70%), подсушенные на воздухе (относительная влажность 40%) и высушенные в сушильной камере (относительная влажность 10%). Средняя крупность кусков до измельчения составляла 70, 50 и 30 мм. Работу, совершенную во время измельчения материала, рассчитывали по зафиксированным данным о потребляемой силе тока при известном напряжении в сети. Установлена закономерность для оценки затрат энергии, требующейся для измельчения отходов окорки ели в зависимости от их относительной влажности и степени измельчения. Показано, что удельная энергоемкость измельчения отходов окорки ели связана с относительной влажностью отходов окорки и степенью их измельчения нелинейной зависимостью, повторяющей структуру закона измельчения Кирпичева-Кика. Отношение теплоты сгорания сухого вещества, содержащегося в продукте измельчения коры ели («энергетическая стоимость»), и энергии, затраченной на ее измельчение («энергетическая себестоимость»), нелинейно зависит от относительной влажности коры, причем у зависимости есть точка экстремума, а именно - минимума. Оптимальная по этому соотношению влажность отходов окорки ели, подлежащих измельчению, составляет 25%. Удельная энергоемкость измельчения отходов окорки ели при оптимальной влажности пропорциональная натуральному логарифму степени измельчения, формула (8). При оптимальной влажности для измельчения отходов окорки ели в 5-15 раз потребуется затратить энергию, составляющую 5-10% теплоты сгорания. В заключение также приводятся предложения о перспективных направлениях дальнейших исследований дробления древесных материалов. The article presents results of experiments on shredding of debarking waste with an industrial shredder Erdwich M600 / 1-400. The experiments use three groups of waste’s humidity: waste immediately after debarking (relative humidity 70%), dried in air (relative humidity 40%) and dried in the drying camera (relative humidity 10%). The average size of the pieces before shredding was 70, 50 and 30 mm. The results set a pattern for evaluating the energy costs required for shredding of debarking waste depending on the relative humidity and the shredding ratio. The results prove that the energy consumption of debarking waste shredding associates with relative humidity of the waste and shredding ratio with a nonlinear dependence, which repeats structure of the Kirpichev-Kik dependence. The paper proves that the caloric value of dry matter contained in the shredding product, and the energy expended in its shredding, link each other as a nonlinear function of the bark humidity with optimal humidity of 25%. The specific energy consumption of the debarking waste shredding at the optimal humidity is proportional to the natural logarithm of the shredding ratio. At the optimal humidity of debarking waste shredding with ratio 5-15 requires expending energy around 5-10% of the waste caloric value. The paper also contains suggestions about further prospective research in the field of wooden materials shredding.

Data centers afford huge energy costs. Saving energy while providing efficient quality of service (Qos) is the goal pursued by data centers. But this is a challenging issue. To ensure the Qos of latency-critical applications, data centers always schedule processors to run at higher frequencies. The continuous high frequency operation will cause great energy waste. Modern processors are equipped with dynamic voltage and frequency scaling (DVFS) technology, which allows the processor to run at every frequency levels it supports, so we focus on how to use DVFS to trade-off between energy and Qos. In this paper, we propose a two-stage strategy based on DVFS to dynamically scaling the CPU frequency during latency-critical workload execution, aimed at minimizing the energy consumption for latency-critical workload which is under the Qos constraint. The two-stage strategy includes a static stage and dynamic stage, which are worked together to determine the optimal frequency for running workload. The static stage uses a well designed heuristic algorithm to determine the frequency-load matches under Qos constraint, while the dynamic stage leverages a threshold method to determine whether to adjust the pre-set frequency. We evaluate the two-stage strategy in terms of Qos and energy saving on the cloudsuite benchmark, and compares the two metrics with the-state-of art Ondemand. Results show that our strategy is superior to Ondemand for energy saving, improving more than 13%.

Energy management is an independent type of professional activity aimed at achieving in the course of any business activity of an enterprise operating in market conditions, reducing costs by improving energy efficiency. Energy management includes a set of measures aimed at saving energy resources: monitoring of energy consumption and energy intensity of products, development of energy budgets, analysis of existing indicators as a basis for drawing up new budgets, development of energy policy, planning of new energy saving measures. This article describes the methodology for determining the energy intensity of products for industrial enterprises, namely energy intensity indicators. These values include: norms of consumption of heat and electricity per unit of industrial production, as well as norms of consumption of fuel and electricity for the supply of heat to the boiler plant of the enterprise. These numbers are indicators of energy efficiency that need to be calculated when implementing energy management systems at enterprises. They are the benchmarks by which the current state of energy efficiency is assessed and planned for the future, taking into account changes in output, implementation or dismantling of equipment, implementation of energy-saving measures, etc. The article shows the calculation of energy consumption of products by the example of a grain elevator.
