Opis: The current practice and the requirements of industrial enterprises in all industrial areas require a detailed display of manufacturing systems course of events. In this paper, we studied the effects and impacts of computer simulation to improve the actual industrial production. We also verified whether the proposed simulation model and its intervention in the logistics of concrete production in a concrete manufacturing enterprise will correspond to reality. The EXTENDSIM simulation software was used. The simulation results utilization in practice has increased the actual production several times. The simulation results indicated that it is necessary to double the intensity of company supply, i.e. a frequency of entry set to 0.15 days for each timber type. This adjustment increased the performance of unutilized devices and the whole manufacturing system several times, up to 54,475 produced building timber elements, which represents an increase of production by about 199.6 % while maintaining company flexibility.

Opis: Background/Purpose: This study investigates the mediating role of decision–making performance in the link between software performance and overall business performance in the logistics sector of an emerging economy. As logistics companies increasingly rely on digital infrastructures, understanding how advanced systems contribute to strategic outcomes is critical for sustaining competitiveness. Methods: A conceptual framework was developed integrating ERP systems, big data analytics, and IoT applications. In this model, software performance is positioned as the independent variable, decision–making performance as the mediator, and business performance as the dependent variable. Data were collected from medium- and large–scale logistics firms and analyzed using regression and bootstrapping methods through SPSS and the PROCESS Macro. Results: The findings reveal that software performance significantly improves decision–making performance (β = 0.552, p < 0.01), which in turn has a strong positive effect on business performance (β = 0.817, p < 0.01). The mediation analysis confirms that decision–making performance mediates the effect of software performance on business outcomes. Conclusion: The results highlight the strategic importance of aligning digital capabilities with organizational decision processes. By demonstrating the mediating role of decision–making, the study highlights that the effective use of advanced analytical tools is crucial for optimizing performance and achieving a sustainable competitive advantage in logistics.

Opis: Energy is an essential component of our daily lives. Despite the expanded use of new and renewable energy sources, oil and gas remain the primary sources of energy. Recently, oil and gas sources have become more vulnerable due to their limited and uncertain availability, as well as geopolitical issues that threaten the security of their supply chains. As a result, securing energy sources in general and oil and gas in particular at reasonable prices and reliable supplies has become a major global concern. As a result, the establishment and operation of energy hubs along energy transit routes between producing and consuming countries is crucial for the security and sustainability of the energy supply. These energy hubs can facilitate the trade and exchange of energy by offering logistics services such as transportation, storage, processing, and distribution. This means that establishing and operating such energy hubs necessitates some logistics requirements. However, previous studies did not tackle the logistics requirements for establishing and operating energy hubs in a single, comprehensive framework. Accordingly, the purpose of this study is to address the logistics requirements of energy hubs, with a focus on oil and gas, and to develop a comprehensive framework for establishing and operating GLEH through conducting an empirical study on the Egyptian oil and gas industry. The study was carried out through seven sequential phases. The study conducted a systematic review of the previous literature using the PRISMA flow diagram and visual bibliometric analysis via VOSviewer software to identify the main research gap and develop an integrated theoretical framework for creating and operating a GLEH. The study then adopted mixed research methods to reap the benefits of both qualitative and quantitative methods. The qualitative technique was used to convert the theoretical framework into a practical framework by conducting semi-structured interviews with key stakeholders. The quantitative method was applied to examine the relationships between the variables and validate the study’s hypotheses in the Egyptian context through a survey. The study set out an applied framework to help establish and operate GLEHs that can improve the security of energy supplies. It also highlighted the key challenges that might face the establishment and operation of GLEHs and suggested strategies to deal with them. The study would contribute to science by developing a unique and comprehensive framework for establishing and operating GLEHs, considering both theoretical and empirical aspects. At a practical level, the proposed framework can help improve the global energy supply chain and its sustainability, especially for oil and gas. It can also be used as a model by other countries and regions to establish and operate logistics hubs for energy and other sectors. Furthermore, the framework can be used in further research to develop the performance of energy hubs.

Opis: This study examines the impact of socio-demographic factors on attitudes towards sustainability and digitalization in logistics and supply chain management. Since a significant gap was identified in this field, study explores how company size, industry sector, and workforce diversity influence strategic planning and operational efficiency within these pivotal sectors of global commerce. The main novelty of the research is to set the roles of technological readiness and knowledge-based factors in shaping organizational responses to sustainability challenges and digital transformation opportunities. By analyzing the correlation between socio-demographic profiles and technological adoption behaviors, the paper aims to provide insights that could help organizations tailor their strategic initiatives to better align with diverse stakeholder needs, enhancing operational efficiency and promoting sustainable practices. This study seeks to fill the gaps in current research by offering a detailed exploration of how sociodemographic diversity impacts the adoption of innovative technologies and sustainability measures within the logistics and supply chain sectors. Results revealed that gender, sector, work position and company size contribute to different understanding and prioritisation of sustainability topics. Managers and team leaders are more focused towards sustainability than the rest of employees and logistics and supply chain sector prefer digitalization over sustainability.
