A sustainable transport solution for a Slovenia town
Matjaž Knez, Ali Naci Celik, Tariq Muneer, 2014, izvirni znanstveni članek

Opis: Authorities in Slovenia and other EU member states are confronted with problems of city transportation. Fossil-fuel-based transport poses two chief problems—local and global pollution, and dwindling supplies and ever-increasing costs. An elegant solution is to gradually replace the present automobile fleet with electric vehicles (EVs). This article explores the economics and practical viability of the provision of solar electricity for the charging of EVs by installation of economical available Photovoltaic modules. A steep decline in the module, inverter and installation costs is reported herein. Present estimates indicate that for the prevailing solar climate of Celje—a medium-sized Slovenian town—the cost would be only 2 euros and 11 cents per kWh of generated solar electricity.

The role of modal verbs in research papers in the field of logistics
Polona Vičič, Klementina Jurančič, 2016, izvirni znanstveni članek

Opis: Research papers, an essential vehicle for disseminating new knowledge and findings, have long been valued for their linguistic objectivity and impersonality. However, more recent approaches to research paper writing suggest that authors should also take an "argumentative position" (White, 2003) by projecting their stance and encouraging the readers to actively engage in the process of reading and evaluating the text (Hyland, 2005; Scollon, 1994). An important linguistic feature, frequently employed for both objective and subjective presentation of claims, is modality and within it modal verbs, which through their modal meanings express different communicative functions. In recognition of genre- and discipline-specific norms, the present paper will focus on quantitative and qualitative analysis of modal verbs and their meanings and functions in logistics research papers, whereby the ultimate goal is to show what practical implications the study's results may have for the teaching of English to students of logistics.

Solar energised transport solution and customer preferences and opinions about alternative fuel vehicles
Matjaž Knez, Marjan Sternad, 2015, izvirni znanstveni članek

Opis: Authorities in Slovenia and other EU member states are confronted with problems of city transportation. Fossil-fuel based transport poses two chief problems - local and global pollution, and dwindling supplies and ever increasing costs. An elegant solution is to gradually replace the present automobile fleet with low emission vehicles. This article first explores the economics and practical viability of the provision of solar electricity for the charging of electric vehicles by installation of economical available PV modules and secondly the customer preferences and opinions about alternative low emission vehicles. Present estimates indicate that for the prevailing solar climate of Celje - a medium-sized Slovenian town - the cost would be only 2.11 EUR cents/kWh of generated solar electricity. Other results have also revealed that the most relevant factor for purchasing low emission vehicle is total vehicle price.

Road traffic safety in conjunction with in-vehicle ITS
Darja Topolšek, Suzana Hribar, Marjan Sternad, 2014, izvirni znanstveni članek

Opis: Interest in Intelligent Transportation Systems comes from the problems caused by traffic congestion, road accidents and air pollution. Traffic congestion continues to grow worldwide as a result of increased motorization, population growth, changes in population density and urbanization. Interest in ITS can also be attributed to reducing road accidents and increasing traffic safety. The most common causes for road accidents are excessive speed, inattentive driving and ignorance of the right-of-way rules. To eliminate these causes, experience, knowledge of traffic regulations and a new car are not enough % vehicle safety systems have to take part as well. Therefore, the European Union issued a directive on the installation of intelligent systems, whose functions are active support during driving, warning the driver in dangerous situations and alerting passengers of the car in case of irregularities in motor function or actions carried out by the driver that may cause danger, such as swerving while falling asleep. These systems help drivers to avoid accidents, and in the event of a collision, an emergency call is automatically made. Furthermore, they can be used to regulate traffic patterns or to reduce engine performance, which would reduce pollution. With these benefits in mind, the EU has indicated to the automotive industry that installation of these new Intelligent Transportation Systems should be mandatory in their new vehicles.

Railway noise reduction by the application of CHFC material on the rail
Brigita Altenbaher, Darja Goltnik, Bojan Rosi, 2015, izvirni znanstveni članek

Opis: Traffic is the most widespread source of environmental noise. Railway noise has become increasingly common in urban areas in the past few decades. Therefore environmental requirements for railway operations regarding noise are becoming very strict and will become even tighter in future. In the present paper we present actual track- based field test performed on Slovenian Railways. The significant noise reduction (up to 30dBA) was achieved by the application of CHFC material on the rail using CL-E1 top anti noise system.

Method for evaluating the throughput performance of shuttle based storage and retrieval systems
Tone Lerher, Banu Ekren, Zaki Sari, Bojan Rosi, 2016, izvirni znanstveni članek

Opis: In this paper a method for throughput performance calculation of shuttle based storage and retrieval systems (SBS/RS) is presented. SBS/RS represent a new technology in automated storage and retrieval systems. Since it is important to design SBS/RS right the first time due to the relative inflexibility of the physical layout, we provide a proposed method for the throughput performance calculation of these systems. The performance of the system is considered as a throughput capacity of the SBS/RS as a whole.

Evaluating costs of vehicle use in military logistics
Leon Grašič, Tone Lerher, Bojan Rosi, 2016, izvirni znanstveni članek

Opis: The article presents an analytical model of evaluating costs of vehicle use in military logistics adapted to specific construction demands and characteristics of military vehicles, profile (conditions and manner) of use and technological procedures of preventive and remedial maintenance of military vehicles. The proposed model of evaluation enables an equivalent comparison of total costs in advance of use of similar vehicles made by different manufacturers throughout the entire operating period (their service life). Initial (entry) and boundary conditions are clearly defined within the proposed model. The implementation of the analytical model ensures the evaluation and planning of maintenance costs and costs of direct vehicle use in military logistics already at the point of purchasing new vehicles, as well as evaluation of optimal operating period (service life) of vehicles, which leads to increased reliability and availability, and, consequently, to more effective use of military vehicles.

Synergies between an observed port and a logistic company
Dejan Dragan, Bojan Rosi, Toni Avžner, 2017, izvirni znanstveni članek

Opis: The paper addresses an analysis of potential synergies in collaboration between an observed Port in the Mediterranean Sea and Central-European logistic railway-services based company. Both companies have established a strategic partnership. The main motive was cooperation in rail transport, with a particular emphasis on potential synergies that would a rail traffic have brought to a port's business. For the purpose of synergies valuation under uncertain conditions, a Monte Carlo simulation-based framework with integrated discounted cash flow (DCF) model is applied. The possible values of future synergies are calculated via the DCF model by simultaneously changing values of different uncertain financial parameters at each repetition of a Monte Carlo scenario-playing mechanism. In this process, predicted forecasts of future synergetic throughputs are also used for various types of observed cargo. As it turned out, the generated synergies' values follow the approximate normal distribution. Based on statistical inference and analysis of probability intervals it was discovered that there might indeed exist certain important synergies in the collaboration between both companies. This fact has convinced us into a belief in the correctness of companies' decision to enter into such kind of strategic cooperation.

Risk management in the pharmaceutical industry in Slovenian companies
Nina Bucalo, Borut Jereb, 2017, kratki znanstveni prispevek

Opis: The pharmaceutical industry is one of the most competitive businesses in the world. Supply chain in this industry has been directed towards the production of large batches to avoid lack of supplies, and the achievement of regulatory requirements, at the cost of high level of inventory, higher costs and inventory write-off due to expiration or other reasons. In recent years this industry is facing major changes and challenges such as intense globalization processes, increased competition and innovations in technologies, which has broadened and deepened risks in supply chain. The paper reports the results of the study of the risk in distribution processes of Slovenian pharmaceutical companies, which was conducted among five companies and aims to draw attention to risks that arise in supply chain, to emphasize the importance of their management and to present a model for an effective assessment of risk in companies, developed at the Faculty of Logistics.

Bullwhip effect in the information flow of a supply chain
Tadeja Lampret, Vojko Potočan, 2014, izvirni znanstveni članek

Opis: The main goal of our research is to analyze and display causes of a bullwhip effect formation within a supply chain, as well as to provide the appropriate solutions to limit the occurrence of the bullwhip effect by using the proper information flow and partners´ cooperation within the supply chain. The bullwhip effect is one of the most important issues in the supply chain management and it is present in many companies. It preserves a character of invisibility because there are lots of causes for its formation and they are usually difficult to discern. The bullwhip effect is a phenomenon of an increase in the order variability within a supply chain. The higher we are within the supply chain, the higher is the order variability. The company encountered with the whip effect can successfully reduce its impact by improving the information flow, as well as improving partners´ cooperation within the supply chain. In this way the company can limit its negative repercussions and increase the profit. The article focuses on the overview of the bullwhip effect within a distribution chain, from its causes to suggestions and measures how to ease its negative repercussions on the organisation. Part of the causes could be found in the market demand variability and in the lack of communication about the actual marked demand within the supply chain. The rest of the causes are related to obstacles that emerge among different partners within the supply chain (role of culture). A qualitative analysis is applied on the basis of the selected cognitions from the supply chain management. The quantitative analysis is based on the theoretical research of the effective flow of information among the participants and its contribution to the reduction of the bullwhip impact. The article discusses two research questions: 1) The correct information flow within the supply chain and the improvement of the communication among partners can lead to the bullwhip effect reduction, and 2) A reduction of the bullwhip influence can lead to the increase of cooperation among partners. The results of the analysis can be used for further research.
