Integrating social dimensions into future sustainable energy supply networks
Matevž Obrecht, Yigit Kazancoglu, Matjaž Denac, 2020, izvirni znanstveni članek

Opis: Environmental protection and sustainable development have become an inevitable trend in many areas, including the energy industry. The development of energy supply networks is strongly correlated with the economics of energy sources as well as ecological and socio-political issues. However, the energy supply network is often distant from the social perspective. This paper therefore combines examination of perceptions and awareness of general public (web-based questionnaire) and top energy experts (a Delphi survey) on the energy supply network and identifies their potential integration in energy supply decision making processes. The results showed that public should be better informed as well as integrated into designing energy supply network as the prosumers gain power and the energy suppliers will no longer dominate the market. Public actors are ready to shape sustainable energy supply and also willing to pay 5.8% more for a sustainable energy supply. The majority are prepared to invest in renewable energy supply network close to their place of residence. Another result is that the public is calling for a shift in priority towards more sustainable and socially friendlier energy supply rather than focusing mainly on the economic and technical perspectives.

Sustainability orientation and focus in logistics and supply chains
Sebastjan Lazar, Dorota Klimecka-Tatar, Matevž Obrecht, 2021, izvirni znanstveni članek

Opis: Sustainable development, logistics, and supply chain are being combined into three increasingly connected and topical global research areas. Therefore, this paper's novelty identifies and defines the priorities of the UN Sustainable Development Goals and sustainable development dimensions in supply-chain- and logistics-management-related studies in the last decade. Knowing logistics and supply chain sustainability focus and orientation is valuable information for researchers and managers to adapt and mitigate their business logistics according to the forecasted trends. The paper provides a systematic and comprehensive review of the literature and is based on 116 scientific papers published between 2010 and 2020 in 73 international journals in the Scopus and Web of Science databases. The study defines focus with integrating environmental, social, and economic sustainability for logistics- and supply-chain-related studies. It emphasizes primary and secondary links of investigated studies with 17 United Nations sustainable development goals. The bibliometric analysis also examined keyword relations. One of the main contributions is that economic sustainability was identified as the most represented one-dimensional sustainability focus. It was revealed that supply chain studies integrated all three sustainability dimensions more frequently (50.60%) than logistics studies, which were equally related to studying two- or three-dimensions of sustainability (39.39%). The most significant findings are also that studies were identified to be oriented primarily towards "responsible consumption and production", "industry, innovation, and infrastructure" and "affordable and clean energy" and secondary especially on "sustainable cities and communities".

Sustainable operations of last mile logistics based on machine learning processes
Jerko Oršič, Borut Jereb, Matevž Obrecht, 2022, izvirni znanstveni članek

Opis: The last-mile logistics is regarded as one of the least efficient, most expensive, and polluting part of the entire supply chain and has a significant impact and consequences on sustainable delivery operations. The leading business model in e-commerce called Attended Home Delivery is the most expensive and demanding when a short delivery window is mutually agreed upon with the customer, decreasing possible optimizing flexibility. On the other hand, last-mile logistics is changing as decisions should be made in real time. This paper is focused on the proposed solution of sustainability opportunities in Attended Home Delivery, where we use a new approach to achieve more sustainable deliveries with machine learning forecasts based on real-time data, different dynamic route planning algorithms, tracking logistics events, fleet capacities and other relevant data. The developed model proposes to influence customers to choose a more sustainable delivery time window with important sustainability benefits based on machine learning to predict accurate time windows with real-time data influence. At the same time, better utilization of vehicles, less congestion, and fewer failures at home delivery are achieved. More sustainable routes are selected in the preplanning process due to predicted traffic or other circumstances. Increasing time slots from 2 to 4 h makes it possible to improve travel distance by about 5.5% and decrease cost by 11% if we assume that only 20% of customers agree to larger time slots.

Supply chain management mitigation to climate change in three selected industrial sectors
Maja Bašić, Špela Kovše, Andraž Opačić, Marijana Pećarević, Matevž Obrecht, 2023, izvirni znanstveni članek

Opis: As the world economy is growing and globalisation is on the rise, climate change and its effects on the planet Earth are also increasing. But climate changes do not disturb only nature; they also affect businesses and their supply chains. Many companies have recently recognised the positive impacts of green and circular supply chain management practices. Supply chains that deliver products from around the world are increasingly exposed to the impacts of a changing climate and scarce resources. In this research, it was determined how climate change impacts supply chains in the food, automobile, and energy industry sectors. Furthermore, we wanted to find out if and how the management of supply chains is altered to adapt to the business environment which is more and more affected by environmental changes.

Sustainability topics integration in supply chain and logistics higher education : where is the Middle East?
Maja Rosi, Matevž Obrecht, 2023, izvirni znanstveni članek

Opis: The global logistics industry has grown significantly in the last decade and has become essential to global business activities. In addition, the logistics industry is vital in transportation, urbanization in the Middle East, and transshipment through the Middle East. Due to their increasing importance and size, there is an increasing demand for adequately qualified people capable of managing the logistics systems and supply chains holistically and sustainably to avoid problems caused by unsustainable practices in mobility, transport, and supply chains. However, it is unclear whether the logistic and supply chain education of future leaders, managers, and engineers will follow SDG goals, the rise of new trends, and green technologies or lag behind. This paper pioneered a systematic approach and analyzed Middle Eastern countries regarding their sustainability integration into higher education programs related to supply chain management and logistics studies. It revealed enormous differences among countries and a lack of sustainability topics in most studied countries. Some countries are also significantly more oriented toward partial logistics challenges such as transport efficiency instead of sustainable supply chains, which are becoming critical challenges for the near future and must be accompanied by formal and life-long learning on sustainability-related topics. The circular economy and corporate social responsibility are especially neglected. It was also revealed that sustainability integration in higher education does not correlate with sustainability scores and the ranking of countries within the sustainability index.

Measuring sustainability in supply chains : comparative study of 15 top logistic companies operating in Slovenia
Petra Serdinšek, Lara Sladič, Matevž Obrecht, 2022, izvirni znanstveni članek

Opis: Our research work refers to measuring sustainability in supply chains. First of all we will touch the topic, what means measuring sustainability in supply chain and how it can be measured. We will focus on our research area of fifteen companies, where we will investigate how much Slovenian companies deal with sustainability in their companies, how much sustainability means to them and how they measure it, if their company contributes a lot to the sustainability of supply chain or to the sustainable operation of the whole company. In recent years, have the supply chains undergone significant changes as a result of the COVID-19 crisis, which has forced companies to change the way of their operating in order to make their supply chains more efficient. The COVID-19 crisis has therefore made companies realize that they need to move to a circular economy, as it has shown the disruption or vulnerability of current supply chains. About sustainability is more and more speech and also more and more companies are recognizing its importance, because sustainable supply chain affects to the entire production process, from the sourcing of raw materials to the recycling of products or raw materials, if this is possible. A sustainable supply chain increases a company’s competitiveness and also reduces costs for the company.

Considering IT trends for modelling investments in supply chains by prioritising digital twins
Milena Kajba, Borut Jereb, Matevž Obrecht, 2023, izvirni znanstveni članek

Opis: Supply chain disruptions and challenges have and will always exist, but preparing in advance and improving resilience for the upcoming consequences should be the utmost important goal. This paper explores trends that affect innovation in the technological sphere of supply chain systems. More precisely, the research is focused on Digital Twin technology applicability through other logistics IT trends and aims to research the pressing issue of ensuring the visibility and resilience of future supply chain systems. The paper’s objective is to produce a conceptual model enabling the investment assessment of the necessary IT resources. Initially, a theoretical confirmation of logistics IT trends’ relevance to supply chain systems was established. After, propositions of Digital Twin technology applications to other logistics IT trends were made, which were divided into corresponding constant multitudes of supply chain systems. Lastly, the conceptual model for the investment assessment of the necessary IT resources was derived in the form of a matrix. It considers 16 parameters for investment assessment and applicability to all companies, regardless of their specifics. It also supports the notion of digital IT competencies’ fundamental importance to the continuous operation of supply chain systems.

A framework for managing future supply chain trends: utilization of lean, agile and leagile strategies
Waleed Rashad, 2020, doktorska disertacija

Opis: The supply chain has become very essential to run any business nowadays. Throughout the history of business, the professionals have been trying always to find out the best practice, and as long as the business concept is evolved over time, the practice, methodologies and techniques of doing the business also have been evolved. This evolvement led to the concept of supply chain initially and then later it became essential to have strategy for supply chain. The evolvement of the markets, globalization, and new technologies became very decisive subjects for building any supply chain and developing its strategy, but there are many other events that may take place which could enforce the supply chain decision makers to change the current approach of running their business. The dynamic business environment and the possible future trends of the global markets represent a real challenge for development of appropriate supply chain strategies, like lean, agility, and leagility. Therefore, it is very important to assess how different possible strategies are suitable for the future changes of the markets? This is to enable the supply chain to be prepared with adequate strategies for different future scenarios. To achieve this aim of preparing the supply chains for the future with adequate strategies, a deep study is done to research lean, agility and leagility, explaining the similarities and differences of these concepts. These strategies are dealing with the most important factors in supply chains; the time and the cost, what is the key reason for selecting these particular strategies lies in the fact, that they are concerned with improving the effectiveness and responsiveness in the supply chain and this is extremely important for the future. We continued study of these strategies by development of three possible future scenarios for energy scarcity, new international monetary system, and wars. The reason of developing these particular scenarios is because they are concerned with the most important political and economic events which could happen and affect the supply chains in the future (EY, 2013; Cook, 2006; Sokov, 2015). These scenarios are established to anticipate the possible challenges which could face the supply chain strategies in the future and to evaluate the suitability of supply chain strategies for such future scenarios. A survey of 150 supply chain professionals, who are working currently in the field of supply chain management, is done in two phases. The first phase is focusing on recognition of the opinions of surveyed supply chain professionals towards the supply chain strategies and their utilization. Based on the theoretical knowledge of the academic literature reviewed in this research, proposed scenarios, and the feedback of professionals in the survey, it was evident that supply chains’ managers need adequate framework, which will support improvement of current and future supply chain management. Therefore, the grounded theory methodology is used to create a new conceptual framework. The core idea of the proposed framework is to improve the global sourcing practice, which consequently will enable improving the management of supply chains according to the predicted scenarios. A second phase of survey is conducted to present the proposed framework to the supply chain professionals for evaluation. The proposed framework adds value to the global sourcing process, which enhancing the supply chain collaboration and helps to support the selected supply chain strategies for consideration – i.e., lean, agility, and leagility, to work better in the future. The proposed framework represents scientific contribution to the supply chain strategies utilization in practice. The results of this contribution are obviously to fill the gap highlighted by the supply chain professionals in the survey, who highlighted the essential need for improvement to the supply chain collaboration globally, and this will be the basic c

Bullwhip effect in the information flow of a supply chain : a role of culture
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.
