The use of ERP systems is becoming an integral part of business information support and allows enterprises to rationalize the use of resources. The purpose of the article is an in-depth analysis of the use of ERP systems in the activities of enterprises, identification of the advantages and limitations of their practical application, which allow the development of ERP systems on the basis of technological, organizational and cognitive convergence to meet the changing needs of modern business. The study used the methods of case analysis, synthesis, and graphical visualization of information. The paper develops the applied aspect of certain areas of modern institutional economic theory, in particular the theory of evolutionary economics. Attention is focused on how the factor of technological progress affects the transformation of company management due to the principle of bounded rationality. The study summarizes the practice of using ERP systems and analyzes the relationship with the processes of convergence of information, communication, management, and cognitive technologies. The factors of rational use of resources based on ERP system data for four types of operating models of companies are identified. They are identified depending on the level of standardization and integration of business processes. Integration contributes to the rational use of resources through the automation of routine processes but requires several business units to use common practices for working with information in terms of its receipt, registration, storage, confidentiality, and distributed access. Standardization brings cost savings and efficiency by unifying and speeding up business processes but limits the ability to transform individual processes to adapt to rapid changes in the environment. The results of the study will help enterprises when implementing or transforming ERP systems to determine their desired configuration, in accordance with business needs, while maintaining the required level of adaptability of business processes. The results will also be useful for researchers conducting comprehensive studies of the impact of information technology on business operations. Technological advances mean that ERP systems continue to evolve and integrate with other technologies, such as artificial intelligence, the Internet of Things, and machine learning, to provide businesses with valuable context that transforms information into unique knowledge, which outlines the prospect for further research.

Even with the state-of-the-art technology of computer-aided design and topology optimization, the present structural design still faces the challenges of high dimensionality, multi-objectivity, and multi-constraints, making it knowledge/experience-demanding, labor-intensive, and difficult to achieve or simply lack of global optimality. Structural designers are still searching for new ways to cost-effectively to achieve a possible global optimality in a given structure design, in particular, we are looking for decreasing design knowledge/experience-requirements and reducing design labor and time. In recent years, Artificial Intelligence (AI) technology, characterized by the large language model (LLM) of Machine Learning (ML), for instance Deep Learning (DL), has developed rapidly, fostering the integration of AI technology in structural engineering design and giving rise to the concept and notion of Artificial Intelligence-Aided Design (AIAD). The emergence of AIAD has greatly alleviated the challenges faced by structural design, showing great promise in extrapolative and innovative design concept generation, enhancing efficiency while simplifying the workflow, reducing the design cycle time and cost, and achieving a truly global optimal design. In this article, we present a state-of-the-art overview of applying AIAD to enhance structural design, summarizing the current applications of AIAD in related fields: marine and naval architecture structures, aerospace structures, automotive structures, civil infrastructure structures, topological optimization structure designs, and composite micro-structure design. In addition to discussing of the AIAD application to structural design, the article discusses its current challenges, current development focus, and future perspectives.

In order to meet the requirements of high precision and rigidity of the two-dimensional turntable, it is necessary to carry out the structural design and position accuracy analysis of the two-dimensional turntable. The study found that the structure of the turntable, the resistance torque, the shaft structure, and the selection and design of the motor and sensor are all key factors affecting the performance of the two-dimensional turntable. In this paper, a method for structural design and simulation of a two-dimensional space turntable is proposed. In the process of structural design, these key factors are analyzed in detail, and the statics, modal and dynamic simulation analysis of the two-dimensional turntable are carried out using ANSYS Workbench software. Through simulation analysis, various indicators of the turntable are checked. Finally, it is concluded that the simulation results fully meet the requirements of the design indicators, which verifies the rationality of the design method and provides a strong basis for the structural design of the two-dimensional space turntable.

Comprehensive implementation of the planning and accounting function is the primary task of the modern enterprise of the manufacturing industry. Rational use of resources radically changes the strategy of the enterprise, which is of particular importance in modern terms, when the most important is the permanent cost reduction, ensuring compliance with the economically justified resource saving mode. People need a modern method of planned calculation of production cost (work, services), functionally oriented to the rational use of production resources in all processes of the value stream. Thus, the aim of the study is to develop the above methodology, the most “deployed” in the direction of information requests for effective management. The author’s observations of phenomena and processes in a number of manufacturing enterprises, their systematization and classification, system analysis, the use of structural-substrate and process approaches, measurement and results’ synthesis allowed to develop a modern methodology of planned calculation integrated into the information method part of an enterprise.

The article discusses methodological approaches to modeling and forecasting the rational use of land resources and the use of geotechnologies. Modeling is performed using the concept of "digital twin" and specially developed criteria for the optimality of the rational land use system. The criteria are rea-sonable from the viewpoint of assessing the socio-economic condition of the territory in strategic planning, and environmental analysis. The criteria also correspond to the indicators that are used to assess the effectiveness of the cadastral system. Geotechnologies are used as a method of predictive modeling. The prototype of the system of rational use of land resources is proposed. The system con-sists of four subsystems: zoning and functional zoning; predictive modeling; long-term planning; monitoring of rational land use based on optimality criteria. The structure of the system of rational use of land resources has been developed, showing the relationship between subsystems and targets which are to be reached as the result of system operation. To assess the rational land use system, optimality criteria have been developed: the stability of the spatial structure to external influences; maximum in-volvement of land resources in economic use; value stability of the real estate object; compliance with regulatory requirements; indicators of the demographic situation; economic efficiency. The imple-mented structure of rational use system of land resources is the structure of the digital twin model for optimizing geosystem management processes. Based on the developed optimality criteria, more accu-rately fine-tuned model and cost-effective and environmentally sound management solutions are de-veloped.

Facing the escalating demands in both technical competence and financial accountability, practicing structural engineers are being forced into an ever-intensified fast-pace working environment. With more and more structural design codes becoming lengthy and cumbersome and, meanwhile, the time allocated for structural engineering design being drastically reduced, the quality assurance of the structural engineering design has been becoming more critical than ever for practicing structural engineers to succeed. Structural engineering design errors and failures have been observed in a variety of design phases and categories. Among them, there are several typical problems needed to be discussed and a systematical procedure of quality assurance of the structural engineering design shall be studied and developed. As a part of our collective professional effort to assure the quality of the structural engineering design, this paper will discuss following eight typical aspects related to quality control and assurance of structural engineering design and a number of real world practical examples will be presented to assist in illustrating the importance of the quality control and assurance for real world structural engineering design projects.

New ways justified to improve technological nature-convergent principles and schemes for the rational use of resources in water treatment and processing. Main principles for the rational use of resources, nature-convergency and ressources substitution were developped. The impact of ultrasound on the production of highly reactive sodium hypochlorite was revealed. The know-how of an active chlorine-containing reagent from underground mineral waters was studied and its effectiveness in disinfecting natural and waste waters of pulp and paper and fish processing industries was proven. A new formula for fertile soil production based on tap water sediment was developed.

Power overhead line regulations and codes generally apply prescriptive methods to the design of structures using working loads multiplied by factors of safety. In contrast, the probabilistic method is founded on designing to a limit state in which strength is matched to stress, with the risk of failure defined by the overlap of the distributions of the limit state model. This work indicates how a stress limit state using probability concepts can be applied to the design of round pole distribution line structures. It indicates that unlike the transmission line, variations which occur in the layout of distribution lines necessitate the use of some contingency factors. Design studies of new and existing lines show that there are substantial savings to be made.

Purpose. The purpose of the article is the formation of theoretical principles of accounting in forestry enterprises on the challenges of the concept of sustainable development, in terms of defining the directions of improving the information support system of rational forestry for the purpose of preservation, reproduction and use of forest resources at the micro and macro levels of the economy. Results. Based on the results of the study, it is established that to ensure the functioning of domestic forestry enterprises on the principles of sustainable development, a necessary condition is to take into account economic, environmental and social goals in management. For this purpose, the directions of economic operations on forest use (harvesting and processing of forest products, reproduction of forest resources) are identified, which can be used as a basis for clarifying the composition of accounting objects specific to forest enterprises for further development of their organizational and methodological support. It is proved that forest resources and losses caused to the environment due to irrational forest use should be reflected in accounting, which will allow forming information support for forest resources management at the microeconomic level. Scientific novelty. The lack of a developed management mechanism that would ensure the conservation, reproduction and rational use of forest resources leads to the loss of national wealth. The evolution of the modern world market economy necessitates the interaction of society and nature, which is based on the postulates of the theory of sustainable development. For forestry, it is the observance of the balance of economic interests of the subjects of forest relations and the protection of forest resources. The above necessitated the delineation of areas for improving the information system of rational forest use in order to preserve, reproduce and use forest resources at the micro and macro levels of the economy. Practical value. The main results of the study can be used: at the microeconomic level (forestry enterprises) – to develop a management mechanism that would ensure the conservation, reproduction and rational use of forest resources; improvement of the system of information support of rational forest use in terms of development of organizational and methodological support of accounting of objects specific to forestry; at the macroeconomic level – to prevent the loss of a component of the country’s national wealth – forest resources; control over the availability and condition of forest resources, which is a component of economic security of the state.

Type 2 diabetes (T2D) constitutes a major health problem, reaching alarming rates over the last decades, especially due to contemporary lifestyle and associated obesogenic environments, as well as the aging population. Diabetes not only causes social consequences but also leads to increasing healthcare costs, posing a significant challenge for the health system. This paper applies a five-step approach for estimating T2D-related costs in Greece. The approach initially estimates the T2D-related ICD10 prevalence and the target population. Next it applies the appropriate therapeutic protocols to identify the most appropriate treatments. Subsequently, it calculates the total cost of medical treatments for each target population, based on the distribution of patients between the different treatments and treatment lines. Finally, based on the diagnostic and treatment protocols, it calculates the annual direct costs associated with the cost categories. Using the estimated future population of the country, the proposed methodology can also project the budget required, under certain conditions, to deal with T2D. The analysis estimated that T2D-related costs in 2021 under rational use of resources were EUR 1,397,871,172.55 billion and EUR 1,512,934,947.63 billion projected in the year 2030 considering the aging effect, per cost category, and in total, presenting an increase of approximately 115 million euros in 2030 compared to 2021. The term “rational use of resources” in this study refers to the use of internationally recognized, evidence-based diagnostic and therapeutic protocols, as adopted by the Greek Ministry of Health. This scenario represents an idealized standard of care rather than actual real-world adherence and is used to estimate the potential resource needs under optimal medical practice conditions. An inflation rate of 4.2% was applied to costs between 2021 and 2030. The analysis showed that the highest percentage (39%) of the total T2D-related healthcare expenditures is associated with complications that occur in T2D patients. Despite a comparatively modest prevalence of T2D in Greece relative to other European and Mediterranean countries, the economic burden associated with its management remains high. The aging of the population will lead to an increase in the total cost of T2D. The applied methodology of estimating budgets by aggregating categories of expenses under a specific disease (ICD10), instead of dividing budgets into categories of expenses, can successfully lead to the optimization and rationalization of expenses according to actual needs. The findings underline the significant economic burden of T2D in Greece, particularly due to complications and population aging. These results emphasize the urgent need for health policy strategies focusing on prevention, early intervention, and the efficient allocation of healthcare resources. The methodology applied can serve as a decision-making tool for forecasting healthcare budgets and optimizing expenditures under different population and treatment scenarios.
