Multicriteria evaluation of intermodal (rail/road) freight transport corridors
Milan Janić, 2020, izvirni znanstveni članek

Opis: This paper deals with the multi-criteria evaluation of the intermodal (rail/road) freight corridors as competing transport alternatives. For such a purpose, the methodology has been developed consisting of two main components; i) the analytical models for estimating the indicators and measures of the corridors’ physical/spatial or infrastructural, technical/technological, operational, economic, social, and environmental performance; and ii) the MCDM (Multi-Criteria Decision Making) method using the above-mentioned indicators and measures of performance as the evaluation attributes/criteria in ranking and identifying the preferred among the several mutually competing freight transport alternative corridors. The proposed methodology has been applied to two Trans-European intermodal rail/road freight transport corridors. As such, it has shown to be of use, in addition to the researchers, also to the other potential DMs (Decision Maker(s)). These could be, for example, the freight shippers/receivers as the users of the already existing intermodal (rail/road) transport services, the transport and intermodal terminal operators and infrastructure providers, and the business and policy makers facing with the problems of allocating the usually limited investments in the social-economic feasible way to the corresponding infrastructure at the local, regional, national, and international scale.

An innovative approach to organizational changes for sustainable processes : a case study on waste minimization
Eva Krhač Andrašec, Tomaž Kern, Benjamin Urh, 2023, izvirni znanstveni članek

Opis: It is necessary to adapt constantly to the business environment with its changing demands. Understanding the objectives, scope, and limitations of actual process changes is crucial, and can be achieved with numerous measures, methods, and techniques. This research demonstrates an innovative approach to organizational changes to enable sustainable processes. In the first part of this research, relevant measures, methods, and techniques are selected through an in-depth literature review. Then, an international online questionnaire is executed among 213 enterprises from four countries. In the last part of this research, the developed approach is tested for the example of waste minimization in the process of developing coatings. Based on the analysis of the survey questionnaire, the usability and benefits of various measures are demonstrated, namely from the point of view of their positive impact on structural and operational efficiency indicators. At the end of the article, a case study presents the success of the innovative approach in terms of 88% waste minimization and up to 48% time and cost reductions in the process of developing coatings. The proposed approach enables better choices to be made and the more efficient use of various measures, which can lead to more sustainable processes and improve the efficiency of enterprises.

Zorica Đurić, Jasna Potočnik Topler, 2021, izvirni znanstveni članek

Opis: Environmental protection and environmental sustainability are becoming increasingly important factors in the hotel business and their competitiveness, in a market that brings numerous benefits. Environmental sustainability is, increasingly, considered one of the most important functions of the hotel business, as well as communication and marketing, which attracts a larger number of guests. Some of the key aspects of hotel environmental sustainability are performance and environmental sustainability indicators, as well as hotel management of environmental performance in order to establish efficiency in that process. The principal question arising is how environmentally sustainable business affects hotel performance, and what are the most important indicators of the environmental hotel business. The aim of this article is to offer an insight into, and analysis of, performance and indicators of the environmental sustainability of hotels through the relevant literature. A case study from Serbia is used to point out the complexity and the significance of these indicators in the hotel business, as well as to emphasise the importance of environmental reports in the case of Serbia. The findings of our study are significant because they help hotel managers identify new opportunities for employing more sustainable processes for saving resources.

Analysis and improvements of the mechanisms for cross-border interchange and activation of the regulating reserves : doctoral dissertation
Marcel Topler, 2022, doktorska disertacija

Opis: This Doctoral Thesis deals with the mechanisms for cross-border interchange and activation of the regulating reserves (RRs), i.e., Imbalance Netting Process (INP) and Cross-Border Activation of the RRs (CBRR), between participating Control Areas (CAs), to reduce the costs of balancing energy. The main objective of INP is to interchange the RRs between participating CAs with opposite signs of interchange power variation. In comparison, the main objective of CBRR is to activate the RRs in participating CAs with the same signs of interchange power variation. Both the INP and CBRR aim to release the RRs and reduce balancing energy as part of the power system's safe operation. The Thesis's main objective is to analyze the impact of the mechanisms for cross-border interchange and activation of the RRs on mutual oscillations of participating CAs and stability for small disturbances. The Thesis's secondary objective is to analyze the impact of the INP and CBRR on frequency quality, on the provision of Load-Frequency Control (LFC), on balancing energy and unintended exchange of energies between participating CAs. Frequency quality in Continental Europe (CE) has been declining in recent years, so it is important that the mechanisms for cross-border interchange and activation of the RRs do not further impair its quality. Both the classic INP and CBRR include a frequency-dependent contribution and, therefore, inherently affect the frequency response of the participating CAs, which is not discussed in the literature. Thus, the impact of the classic INP and CBRR on frequency quality and the provision of LFC is thoroughly evaluated with dynamic simulations of a three-CA test system and eigenvalue analysis of a two-CA system. It is demonstrated that both the classic INP and CBRR reduce the damping of the entire power system. Therefore, a modified implementation of the classic INP and CBRR is presented, and improved INP and CBRR are proposed, which have no impact on the mutual oscillations of participating CAs and stability for small disturbances. Furthermore, the dynamic simulations results confirm that the frequency quality can be improved by the classic INP and CBRR, although there are also cases where it can deteriorate. However, the improved INP and CBRR generally improve the frequency quality in all cases. The improved INP and CBRR also enhance the provision of LFC compared to the classic INP and CBRR. Moreover, the improved INP and CBRR reduce the unintended exchange of energies, thus increasing the economic effects of the INP's and CBRR's activation. The improved INP increases energy exchange, therefore positive economic benefits can be expected in comparison to the system with the classic INP. However, the improved CBRR reduces energy exchange, therefore positive economic benefits can be expected in comparison to the system with the classic CBRR, since energy exchange is paid by CA via bidding process.

Edeltraud Günther, Daria Meyr, Natalia Mikhalenok, Pavel Pervov, Elena Gerasimova, Iurii Kholopov, Elena Lukenyuk, 2016, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Opis: Environmental reporting aims to measure, disclose and to be accountable to internal and external stakeholders about to what extent the company uses the functions of the environment and takes action to improve environmental performance. Thus, the communication of a company has two objectives: for internal stakeholders’ environmental performance is measured in order to prepare decisions of corporate management, for external stakeholders the reporting on the environmental management system, the environmental performance, the ecology orientation of the value-added steps, the dealing with stakeholders and process and product innovations as well as environmental objectives are in the foreground. Finally, it should be noted that environmental reporting is increasingly part of sustainability reporting.

Production control of a polymerization plant based on production performance indicators
Dejan Gradišar, Sebastjan Zorzut, Vladimir Jovan, 2008, izvirni znanstveni članek

Opis: The specifics of process manufacturing have a great influence on production management. The focus of process-production control is to maintain stable and cost-effective production within given constraints. The synthesis of production-control structures is thus recognized as one of the most important design problems in process-production management. This article proposes a closed-loop control structure with the utilization of production-performance indicators (pPIs) as a possible solution to this problem. Suggested concept takes into account also economic issues of production. pPIs represent the translation of operating objectives, such as the minimization of production costs, to a reduced set of control variables that can then be used in a feedback control. The idea of production-feedback control using production pPIs as controlled variables was implemented on a procedural model of a production process for a polymerization plant. Preliminary results demonstrate the usefulness of the proposed methodology. At the implementation stage we must be aware that appropriate IT system has to be available which ensures needed online production data.
