Статья: IMPACT OF TRANSPORT SYSTEM DEVELOPMENT ON CO2 EMISSION LEVEL (2024)

Современная геополитическая картина мира стала для многих стран серьезным вызовом. Помимо множества различных турбулентных явлений, в глобальной экономике текущего периода можно также наблюдать изменения в логистических и транспортных путях между странами. Наряду со сменой ролей, борьбой за различные геополитические интересы, вопросы транспортных коммуникаций и возможностей стран с точки зрения транзита выходят на первый план. Проблема развития транспортных логистических путей для Армении стала еще более насущной и требующей незамедлительного решения. Ключевой целью исследования стала оценка возможностей транспортной логистики Армении с точки зрения ее взаимодействия как со странами ЕАЭС, так и с третьими странами, в том числе в ракурсе расширения реэкспорта последние несколько лет. Методология исследования основана на анализе влияния транспортных коммуникаций на экономическое развитие и благосостояние Армении. Использованы методы качественного и статистического анализа, а также наблюдение и синтез. Информационная база включает статистику грузоперевозок и товарной структуры торговли Армении с ЕАЭС и третьими странами. В результате выявлено, что существующая транспортная логистическая система Армении слабо развита и существенно тормозит развитие экономического потенциала страны. Основным выводом исследования стал тезис о необходимости развития логистических транспортных систем, с целью положительного воздействия на экономический рост и развития Армении в долгосрочной перспективе.

This study examines the role of government subsidies and private sector lending in stimulating China’s economic growth while assessing the prospects for expanding the social credit system. This study covers the period from 1990 to 2023 and is based on data from the National Bureau of Statistics of China, the World Bank and the International Monetary Fund. The paper applies theoretical analysis, as well as correlation and regression methods, to assess the long-term impact of various types of subsidies on macroeconomic indicators. The article examines theoretical models describing the relationship between social subsidies and economic growth and analyzes government subsidy programs. Special attention is given to the analysis of the social credit system, which evaluates the behavior of citizens and organizations, encouraging compliance with laws and regulations to enhance social stability and predictability in economic agents’ behavior. The findings demonstrate significant correlations between the volume of social subsidies and economic growth, indicating that social subsidies encourage household spending. However, the long-term effectiveness of subsidies in increasing productivity and innovation remains limited. In conclusion, it is noted that there is a need to improve the mechanisms for distributing subsidies and integrating the social credit system in order to achieve more effective economic growth, taking into account the need to maintain social stability in Chinese society.

Mining and metallurgical companies (MMCs), as budget-forming and city-forming enterprises, have an impact on related sectors of the economy and are also affected by changes in other industries. In particular, MMCs are exposed to imbalances from structural crises. The article systematises the types of economic crises, substantiates their significance, and highlights relevant features. A pertinent observation is the increasing role of the risk management system as part of the effective management of the whole enterprise. To promptly respond to external challenges, MMCs must transform internal corporate risk management systems. We propose that such a transformation requires the implementation of a risk control system (RC) based on an integration approach. We present an RC system that involves step-by-step and coordinated risk management and business processes of the MMC. To this end, we formulate the requirements for developing a risk management system, considering the specifics of the MMC and the features of structural crises. We then develop the structural and logical schema of the RC system. This scheme is decomposed and divided into procedures to demonstrate the interaction between the enterprise management system and the risk management system. Some advantages of the proposed RC system include its integration approach and the underlying principles of balance, interconnection, and coordination, which provide connectivity with the company’s corporate management system and allow the consideration of the impact of structural crises and other factors through benchmarks comprising risk factors.

Allocation of operations to work centers is a key management task in modern production systems. Its relevance stems from the need to optimize the use of limited resources to achieve high efficiency and productivity. However, the problem is complicated by the combinatorial complexity associated with the discrete nature of operations and the need to consider multiple factors, including resource constraints, time constraints, and process requirements. This requires specialized approaches to find efficient solutions. This paper is devoted to analyzing such approaches. The paper considers actual problems of optimization of operations distribution to work centers in modern production systems. Particular attention is paid to the problems of minimizing variable costs associated with the changeover of equipment and increasing the overall efficiency of production processes. The paper considers the limitations of classical optimization methods such as linear programming, a review of modern approaches, including combinatorial algorithms, methods of the theory of schedules. Special attention is paid to heuristic algorithms, such as genetic algorithms, simulated annealing, and ant algorithms, which allow us to find acceptable solutions in a short time. The paper also discusses the key factors affecting the scheduling, such as resource constraints, time constraints, and technological requirements. Considering the conditions of the production problem posed in the paper problem and based on analyzing the advantages and disadvantages of existing methods of its solution, as an alternative it is proposed and substantiated the use of multi-agent approach with the application of heuristic algorithms for the distribution of work operations at production enterprises.
