    APPROACH TO DEVELOPMENT OF THE LEAN CONCEPT PROJECT
    (University POLITEHNICA Timisoara, Faculty of Engineering Hunedoara, 2023) Marić, Bogdan; Medaković, Vlado; Kiss, Imre
    We are on the threshold of joining the European Union (EU) and our business environment is experiencing a severe economic and financial crisis, which is a part of the global crisis. Based on the fact that mental and technological creativity grows just in times of crisis, the Lean concept is gaining recognition and becoming a challenge to future scientists, researchers and entrepreneurs in our country. Inspired by the Japanese automotive industry, it is synonymous with a good way to get out of the crisis. The time of crisis in giving us the best time to develop the strategies of work process improvement and the application of Lean concept. The crisis facilitates the use of new paradigms with completely new mental models in the business of organizational systems. This concept provides a focus on people, their training in work processes, teamwork and continuous improvement. They are crucial for the efficiency level in the use of key resources: people, techniques, property or capital invested in human labour performance.

    CHARACTERISTICS AND POSSIBLE ENTREPRENEURIAL PROFILES
    (University Politehnica Timisoara, Faculty of Engineering Hunedoara, 2019) Medaković, Vlado; Marić, Bogdan; Imre, Kiss
    Entrepreneurship implies the directing of resources in the area of their optimal use, while entrepreneur implies the person who acts, who gives concrete forms to jobs, who anticipates risk, create new forms of jobs, expands employment, and enables better and more efficient organization of enterprises capable of meeting all the challenges put in front of it. The role of entrepreneurship is universal. It includes almost all aspects of human life. Every society uses entrepreneurs’ experience in management, support and success encouragement, resource activation, motivation and risk awarding, business efficiency, stability and growth, taking responsibility and business risk. Entrepreneurs see their chances where others see confusion and chaos. Key players enabling such changes are free entrepreneurs, young entrepreneurial managers, persistent innovators, and creators of a new business world.

    CHARACTERISTICS OF BUSINESS INCUBATORS
    (Faculty of Engineering Hunedoara, University Politehnica Timisoara, 2020) Medaković, Vlado; Marić, Bogdan
    The paper presents general characteristics of entrepreneurial infrastructure - business incubators. One of the modern ways of support to small newly established enterprises and entrepreneurs, which are in a development life phase, is the system of technological infrastructure: entrepreneurial incubators, technology centres, science parks and business zones. Those are different organizations which help entrepreneurs to develop their business ideas and to overcome more easily the initial problems in business, for which, in a wider context, the term business incubators is used, and also the clusters related to entrepreneurs who are in an advanced phase of entrepreneurship. An incubator is extremely suitable for newly founded small enterprises, which do not have their own business premises, sufficient funds and experience, on one hand, but, on the other hand, they have entrepreneurial ideas, goals and determination to do business. The opportunity to give local and regional support to newly founded and small enterprises by means of business incubators in Bosnia and Herzegovina is significant because it delivers the key elements for the development of incubators, such as unused spaces in all municipalities, that can be easily transformed into a workspace and adapt to the needs of new entrepreneurs.

    DESIGN OF WORKING UNITS IN THE MANUFACTURING SYSTEM OF TOOL MACHINES REPAIR
    (University Politehnica Timisoara, Faculty of Engineering Hunedoara, 2022) Marić, Bogdan; Medaković, Vlado; Imre, Kiss
    The paper investigates the possibility of applying the concept of production on the principle of the group technology. To make that possible, it is necessary to have a stable production program as one of the most influential factors in the choice of spatial structure. The following factors have been observed: the process of grouping parts of machine tools in the overhaul by applying the classification system and subject approach in the construction of production structures. Еmpirical research has been related to the classification and categorisation of parts - production programs. In the second phase, the analysis of classification and operational similarity of parts in the machine tools overhaul process has been performed. Тhe third phase has been related to the analysis of the representation of operational groups of individual machine tools in relation to the total number of formed operational groups in the machine tools overhaul production system. Research has shown that there are certain laws in the formation of operational groups, which can reliably assess the impact of analysed factors on the formation of permanent work units in terms of equipment allocation and workplaces (layout) regardless of the introduction of different types of machine tools in the overhaul process, and that has enabled the overhaul process efficiency increase in the overhaul system.

    ELIMINATION LEAN WASTE IN THE PRODUCTION PROCESS
    (Technical faculty "Mihajlo Pupin", University of Novi Sad, 2021) Gojković, Ranka; Moljević, Slaviša; Marić, Bogdan; Medaković, Vlado
    To survive in the market, it is necessary to develop a new approach to improve the production process. Waste elimination represents great potential in terms of improving the production process. To eliminate wastes, it is necessary to perform an analysis of the work process, to identify all the causes that lead to wastes and, based on that, to plan and implement improvement measures to reduce or eliminate these wastes. In this paper, it is proposed to eliminate Lean wastes by eliminating the failures that lead to them. Identifying and eliminating failures also leads to eliminating wastes. The Ishikawa diagram was used to identify failures. By applying the failures elimination method, Lean waste will also be eliminated.

    POSSIBILITIES OF IMPLEMENTATION OF THE BALANCED SCORECARD METHOD IN HIGHER EDUCATION
    (Faculty of Engineering, Center for Quality, 2015) Marković, Nenad; Petković, Darko; Moljević, Slaviša; Marić, Bogdan; Gojković, Ranka
    This paper describes the application of the BSC to the existing strategy of the university. With its application an unbalanced strategic state is translated to the balanced state on the way of equal engagement of all resources and segments of functioning of HEI. After the estimated needs for the establishment of a BSC, existing strategic goals of HEI are translated into KSF, and later in the KPI, on which basis is the proven original use of the BSC, and that is translating strategy into an understandable set of indicators. On that way the number of original KPI is reduced on the acceptable number for monitoring and decision making. Creating a strategy map is a simplified picture of the strategy and provided a contribution to the effective implementation of the strategy through the understanding of key parameters of all relevant perspectives of functioning.

    (Mašinski fakultet, Univerzitet u Zenici, 2018-05) Marić, Bogdan; Medaković, Vlado; Brdarević, Safet; Jašarević, Sabahudin
    U radu je izvršena analiza problema procesa održavanja mašina i postrojenja. Održavanje tehničkih sistema (mašina i uređaja), odnosno sredstava za rad, kao funkcija i dio procesa proizvodnje zauzima danas važno mjesto u proizvodnom sistemu svake organizacije, odnosno proizvodnog sistema. Na razvoj održavanja uticao je brz industrijski napredak, kao i stalni porast automatizacije i povezanosti sredstava za rad, zatim nagli porast fiksnih troškova u odnosu na promjenljive. Sredstva se tokom vremena troše i smanjuje im se radna sposobnost. Sredstva za rad su podložna kvarovima, lomovima i oštećenjima, pa se pojavljuju prekidi u radu. To uzrokuje pojavu troškova zbog zamjene i popravke dijelova, ali i troškove zbog zastoja u procesu proizvodnje. Postojeći modeli upravljanja održavanjem tehničkih sistema imaju za cilj obezbeđenje željene pouzdanosti i raspoloživosti sistema, po mogućnosti uz što manje troškova.
