В настоящее время эффективность проведения мероприятий, связанных с улучшением условий и обеспечением безопасности труда работников промышленных предприятий, в том числе в судостроительной отрасли, оценивается, главным образом, с применением социальных показателей (сокращение количества рабочих мест с неблагоприятными условиями труда, снижение уровня производственного травматизма, сокращение текучести кадров и другие). Вместе с тем, существует актуальная потребность в оценке экономической эффективности указанных мероприятий, что необходимо для рационального расходования финансовых ресурсов, выделяемых на обеспечение производственной безопасности. Специалистами профильных организаций были предложены методические разработки в области оценки экономической эффективности мероприятий по улучшению условий труда, но их практическое использование затруднено в связи с отсутствием релевантной методики определения исходных величин для расчета данных показателей. На основе анализа упомянутых разработок, авторы применили к ним результаты собственных исследований и предложили адаптированную методику экономического обоснования рассматриваемых мероприятий. В статье приведена структура затрат на компенсацию негативного воздействия производственной среды на работников. Предложен метод определения значений исходных величин (данных) для расчета показателей социально-экономического эффекта. Приведены показатели, позволяющие учесть влияние рассматриваемых мероприятий на производительность труда, а также оценить сумму экономии расходов на компенсационные выплаты. Изложенные в статье предложения по расчету социально-экономического эффекта от проектируемых (планируемых) мероприятий по улучшению условий и безопасности труда позволяют повысить точность расчетов и объективность выводов об экономической эффективности рассматриваемых мероприятий. Что, в свою очередь, позволит обеспечить повышение экономической эффективности конечных результатов работы предприятия. Nowadays, the effectiveness of measures related to improving conditions and ensuring the safety of workers of industrial enterprises, also including the shipbuilding industry, is usually rated by using social indicators (reduction in the number of jobs with unfavorable labor conditions, reduction in the level of industrial injuries, staff turnover reduction and others). At the same time, there is an urgent need to assess the cost-effectiveness of these activities, due to the need to rationally spending the financial resources allocated to ensure industrial safety. Experts of specialized organizations suggested methodological developments for diagnosis economical effectiveness of events to improve jobs condition. Practical usage of these methods is difficult due to the lack of relevant methods for defining initial values which are used in calculations. Based on the analysis of the mentioned developments, the authors applied the results of their own research to them and proposed an adapted methodology for the economic justification of the measures under consideration. The article presents the cost structure for compensating the negative impact of the labor environment on workers. A method for determining the values of the initial values (data) for calculating indicators of the socio-economic effect is presented in article. Demonstrated indicators allow to represent the influence of events on working efficiency and to measure the spend savings on compensative payments. Described proposals for social-economic event efficiency calculation methodology allow to increase the calculation accuracy and make adequate conclusions of event's social-economy efficiency. This, in turn, will lead to improve the economic effectiveness of the final results of whole enterprise.

Seasonal Factor

The article proposes a method for predicting the daily energy consumption level for every day of a whole year, taking into account the season-al factor, based on only twelve actual power consumption data by the months of the year. Then a mathematical model is developed for moni-toring and controlling the level of electricity consumption on a daily basis, taking into account the seasonal factor. The model is consistent with a common model for the length of daylight (in hours). In addition, on the basis of this model, a method of monitoring and diagnostics of electricity consumption is presented, which will allow users to monitor the level of power consumption and be timely notified of any deviations from the theoretical level. Finally, this method gives rise to the operational principle for a proposed device, a smart energy meter, for detecting suspicious deviations from the theoretical level. The device will help timely detect over-consumption (or under-consumption) of electricity in order to take preventive measures. The proposed method consists of the following steps: (1) choice of a function to model the level of electricity consumption (theoretical calculated level), (2) choice of a tubular control neighborhood of the graph of the model function, (3) choice of a criterion on when the smart energy meter should notify the user of an unexpected deviation from the theoretical level in the case of exit from the tubular control neighborhood.

Вопрос энергообеспечения зданий и сооружений на территориях с малоразвитой инженерной инфраструктурой и децентрализованными системами частично может быть решен применением солнечных систем теплоснабжения (или горячего водоснабжения). Подобные системы - надежные, безопасные, простые и малозатратные в эксплуатации, сокращают потребление традиционных энергоресурсов и эмиссию вредных выбросов в атмосферу. Возможность массового внедрения гелиоустановок в основном сдерживается стоимостными показателями, определяющими срок окупаемости. Ежегодный рост цен на традиционное органическое топливо, возможность изготовления солнечных коллекторов собственными силами и средствами может повысить их привлекательность. В работе произведена оценка рентабельности солнечной системы горячего водоснабжения гостиницы, расположенной в селе Бабяково Воронежской области для двух временных периодов (2005 г. и 2021 г.) с учетом повышения стоимости на электроэнергию, являющуюся основным традиционным энергоресурсом. Солнечные коллекторы гелиосистемы производятся собственными силами и средствами. Внедрение гелиоустановки для нужд горячего водоснабжения в традиционную систему теплоснабжения гостиницы позволит сократить потребление электроэнергии на 44 %. В работе показано, что повышение цены на электроэнергию за период с 2005 г. по 2021 г. не компенсировало рост стоимости материалов на изготовление солнечных коллекторов. При этом срок окупаемости для 2005 г. составлял 6,0 лет, для 2021 г. - равен 13,1 годам. Эффективная эксплуатация соответствует периоду 6,9 лет. Установка относительно российских и зарубежных производителей по затратам занимает среднее положение. При стоимости электроэнергии на уровне европейского рынка (2021 г.) срок окупаемости составляет 1,4 года. The issue of energy supply of buildings and structures in areas with poorly developed engineering infrastructure and decentralized systems can be partially solved by the use of solar heat supply systems (or hot water supply). Such systems (reliable, safe, simple and low-cost in operation) reduce the consumption of traditional energy resources and the emission of harmful emissions into the atmosphere. The possibility of mass implementation of solar plants was largely constrained by cost indicators that determined the payback period. The annual rise in prices for traditional organic fuels, the ability to manufacture solar collectors with their own strength and means can increase their attractiveness. The work assessed the profitability of the solar hot water supply system of a hotel, located in the village of Babyakovo, Voronezh Region, for two time periods (2005 and 2021), taking into account the increase in the cost of electricity, which is the main traditional energy source. The solar collectors were produced in-house. The introduction of a solar plant for the needs of hot water supply in the traditional heating system of the hotel can reduce electric energy consumption by 44 %. The paper shows that the increase in the price of electricity for the period from 2005 to 2021 did not compensate for the increase in the cost of materials for the manufacture of solar collectors. At the same time, the payback period for 2005 was 6,0 years, for 2021 was equal to 13,1 years. Efficient operation of the plants covers a period of 6,9 years. The installation of Russian and foreign manufacturers in terms of costs occupies an average position. With the cost of electricity at the level of the European market (2021) the payback period is 1,4 years.
