This study analyzes the energy management approach as one of driving factors for sustainable development, not only in enterprises, but also countries. Sustainability an enterprise is defined its tendency to meet need customers and stakeholders through creative innovative business strategies well activities that have a positive influence on society environment. In this study, sustainability measured application system, wood industry, which has increasingly significant impact economic...

Abstract The six Western Balkan countries (WB6), which include Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia, Serbia, are in a critical phase of their development face various economic, political environmental challenges. Political uncertainties, economic imbalances, institutional weaknesses have hindered progress achieving sustainable goals. Among these challenges, the energy sector stands out as priority due to its significant impact on growth, climate change,...

The lean approach is based on more efficient use of resources and eliminating all kinds waste that do not add value for customers. Lean manufacturing considered a necessary strategy generating financial performance sustainable finance. There are positive links between green paradigms, so the connection has strength in business communities, industry academia. One main aims this paper to explore highlight synergies practices. In addition, catalyst total reduction, interdisciplinary aspects...

Assessing energy performance indicators is important for understanding EU countries' progress toward achieving sustainability and climate goals, including reducing greenhouse gas emissions increasing the share of renewable energy. This paper employs two-step cluster analysis (TSCA) using IBM SPSS 26.0 to classify member states based on six key indicators. The optimal number clusters was determined Schwarz's Bayesian Information Criterion (BIC), ensuring statistical robustness. Four distinct...

The study represents a new approach of analyzing energy poverty using an intelligent method based on social factors. Energy one the most vital problems, especially in recent years, with serious implications social, economic, environmental, political, and health sphere. Identifying measuring parameters challenge not only national, but also regional level. This research to neural network application systems resource planning activities aim real socio-economic data. analyzed data are associated...

The aim of this paper is to propose a model for an energy management system (EnMS) in the hospitality industry line with ISO 50001 standard. new proposed model, specifically developed service organizations, was based on Plan–Do–Check–Act cycle and confirmed 280 hotels Western Balkans 6 (WB6) region. data were used investigate if hotel properties represent influential factor wider implementation EnMS requirements. standard, into sub-categories, including actual regulations legislation within...

This study aims to present the impact of disasters, such as COVID-19 pandemic, on possibility recovering from and mitigating impacts. The paper proposes a new emergency planning disaster recovery management model (EPDRM) which links ISO 31000:2018 (Risk Management) requirements with process approach. was validated through its application ISO-certified ISO-non-certified hotels. analysis performed by using an online questionnaire based requirements, where given questions were grouped into 14...

In times of increasing awareness sustainability and the need for efficient business processes, this study explores integration process reengineering with circular economy principles within Serbian manufacturing organizations. Addressing sustainable development, research aims to propose validate a model that harmonizes improve environmental organizational performance. The conducted an extensive survey analysis across 135 organizations in Serbia, assessing their readiness current practices...

A polygeneration system is an energy capable of providing multiple utility outputs to meet local demands by application process integration. This paper addresses the problem pinpointing optimal supply for a livestock farm in terms configuration and capacity. The optimization presented solved case study pig paper. Energy farm, as well super-structure were modelled using TRNSYS software. Based on locally available resources, following modules chosen analysis: biogas fired internal combustion...

The paper aims at examining the possibilities of enhancing higher education process using quality tools, from perspective number passing exams, after introducing Bologna process. One goals is modernisation teaching by e-learning. Several tools are used, such as: Pareto analysis, Statistical Process Control and Ishikawa diagram. After defining defects (seven basic types waste) that have a negative influence on final evaluation how these can be eliminated, analysis done, which used for...
