. Investigation of the effectiveness of Laravel-based web applications in various php execution environments//Science online: International Scientific e-zine - 2025. - №12. - https://nauka-online.com/en/publications/information-technology/2025/12/04-39/

Annotation: The article is dedicated to the study of the efficiency of web applications built on the Laravel framework in different PHP runtime environments, such as PHP-FPM, Apache/mod_php, and Nginx. It also covers high-performance solutions based on long-lived processes, like Swoole and RoadRunner, as well as Laravel Octane. A comparative analysis of the architectural features, startup costs associated with the framework, and the impact of different server configurations on bandwidth and HTTP request processing delays was conducted. Based on the experimental data from synthetic tests and real-world cases, recommendations were formulated for selecting a runtime environment and optimizing Laravel apps for different workload scenarios.

Bibliographic description of the article for the citation:

. Designing microgrids with renewable energy sources and energy storage systems//Science online: International Scientific e-zine - 2024. - №6. - https://nauka-online.com/en/publications/technical-sciences/2024/6/06-30/

Annotation: The article discusses the design of microgrids that use renewable energy sources and energy storage systems as a controlled local power system that operates in both grid-connected and island mode. The goal is to present an integrated approach that combines the choice of architectural design (AC/DC/hybrid), the selection of distributed energy resources (DER) and energy storage systems (ESS), and management requirements (power quality control, energy management system) within the framework of the IEEE 1547 and 2030 standards. Key methods for modeling and optimization, such as multicriteria and stochastic optimization, are described, as well as the main challenges to implementation, such as variability in generation, cyber resilience, and costs. Examples of successful projects demonstrate improvements in reliability, flexibility, and economic efficiency for local power systems.

Bibliographic description of the article for the citation:

. The impact of modern ERP systems on supply chain management//Science online: International Scientific e-zine - 2025. - №4. - https://nauka-online.com/en/publications/economy/2025/4/19-7/

Annotation: Amid accelerating global digitalization of business processes, the integration of ERP systems into supply chain management has become a key factor in determining the competitiveness of modern enterprises. The aim of this article is to provide a multifaceted analysis of the transformational impact of enterprise resource planning (ERP) platforms on logistics operations, with a focus on identifying and describing mechanisms that enhance the efficiency of material flows. Ongoing academic debates reveal significant contradictions regarding the optimal level of ERP system customization, the role of the human factor in implementation, and the potential for integration with Industry 4.0 technologies. Based on a structured review of relevant publications, it is observed that the comprehensive integration of ERP platforms into supply chain architecture leads not only to quantitative improvements in operational performance—such as inventory reduction and enhanced forecasting accuracy—but also to a qualitative transformation of managerial paradigms. In this context, the author outlines a perspective on the development of workforce competencies within the digital ecosystem. The content presented in this article is valuable for logistics managers, system integrators, and the academic community engaged in research on the digital transformation of business processes.

Annotation: In the modern global business environment, characterized by instability and uncertainty, strategies for optimization and production placement acquire particular significance. Enterprises face unforeseen challenges, such as economic fluctuations, political instability, and the impact of global crises. In such conditions, there is a necessity to develop strategies that enable the optimization of production and efficient placement of manufacturing resources. This article aims to explore and highlight the key aspects of optimization and production placement in an unstable business environment. It considers not only the technical aspects of these issues but also strategic solutions that allow enterprises to adapt and anticipate changes in the economic and social landscape.
