Innovative energy system using renewable energy sources for high-temperature heating
No full textV zaključnem delu smo zasnovali novo procesno shemo sistema visokotemperaturnega daljinskega ogrevanja katerega cilj je učinkovito ter ogljično nevtralno delovanje.
Sistem je sestavljen iz gorivne celice vezane z dvostopenjsko kompresijsko toplotno črpalko. Gorivne celice so naprave za pretvorbo energije, ki proizvajajo elektriko (in toploto) neposredno iz plinastega goriva z elektrokemično kombinacijo goriva in oksidanta. V našem sistemu je gorivo zemeljski plin. Proizvedena elektrika iz gorivne celice samo zadostno oskrbuje toplotne črpalke ter hkrati proizvaja toploto, ki le te razbremenjuje.
Skonstruirali smo osnovno shemo in dve dodatni alternativi, z dodanim vmesnim prenosnikom in zaporedno vezanimi toplotnimi črpalkami in jih primerjali pri različnih pogojih. V primeru temperature povratka 60 °C in končni temperaturi ogrevanja 80 °C osnovna shema z vmesnim prenosnikom toplote obratujeta pri COP vrednostih 3,15 oz. 3,21. Najvišje vrednosti COP smo zasledili pri zadnji alternativi in sicer 3,86, vendar ta ni samo zadostna in tako nastanejo dodatni stroški nakupa elektrike. Konkurenčnost in inovativnost sistema ne moremo meriti le s COP vrednostjo. Najboljši rezultat dobimo z \u27izkoristkom\u27 zemeljskega plina. Omenimo, da ne gre za navaden izkoristek, ampak utilizacijo - razmerje med dobljenim toplotnim tokom, ki se neposredno prenese na ogrevano vodo in vloženim toplotnim tokom zemeljskega plina na podlagi HHV in LHV. V osnovni shemi in z vmesnim prenosnikom dosežemo 251,62 % oz. 261,37 % glede na HHV ter 225,21 % oz. 233,99 % glede na LHV. Alternativa z zaporedno vezanimi toplotnimi črpalkami dosega 277,41 % glede na HHV in 247,38 % glede na LHV, vendar ni samo zadostna.In the master thesis, we designed a new flowsheet for a high-temperature district heating system, the goal of which is efficient and carbon-neutral operation.
The system consists of a fuel cell connected to a two-stage compression heat pump. Fuel cells are energy recovery devices that produce electricity (and heat) directly from a gaseous fuel through an electrochemical combination of fuel and oxidant. In our system, the fuel is natural gas. The electricity produced from the fuel cell self sufficiently supplies the heat pumps and at the same time produces heat that relieves them.
We constructed a basic scheme and two additional alternatives, with an added intermediate heat exchanger and series-connected heat pumps then compared them under different conditions. In the case of a return temperature of 60 °C and a final heating temperature of 80 °C, the basic scheme and with an intermediate heat exchanger operate at COP values of 3.15 and 3.21 respectively. The highest COP values were found in the last alternative, namely 3.86, but it\u27s not self sufficient and thus additional costs of electricity purchase arise. The competitiveness and innovation of the system cannot be measured only by the COP value. The best result is obtained with the utilization of natural gas. It\u27s calculated as a ratio between the obtained heat flow, which is directly transferred to the heated water, and the input heat flow of natural gas based on HHV and LHV. In the basic scheme and with an intermediate exchanger, we reach 251.62% and 261.37% respecivetly with respect to HHV and 225.21% and 233.99% respectively according to LHV. The alternative with series-connected heat pumps achieves 222.31% with respect to HHV and 277.41% with respect to LHV, but it is not self sufficient
Hydrothermal gasification of lignocellulosic biomass
No full textPrekomerno izčrpavanje in zanašanje na energijo, pridobljeno iz fosilnih goriv, je privedlo do globalnih podnebnih sprememb in onesnaževanja ozračja. S tem namenom so največje industrije začele z uveljavljanjem okolju bolj prijaznih praks, ki bi hkrati zmanjšale odvisnost od neobnovljivih virov energije, ki so v pomanjkanju. Lignocelulozna biomasa je najobsežnejša in biološko obnovljiva biomasa na Zemlji, ki kaže velike potenciale za zamenjavo fosilnih goriv kot primarni vir energije. Sestavljena je pretežno iz celuloze (40–60 %), hemiceluloze (20–40 %) in lignina (10–24 %), ki predstavljajo bogat vir surovin za proizvodnjo biogoriv. Raziskave na področju lignocelulozne biomase se osredotočajo na iskanje alternativnih postopkov, s katerimi bi lahko lignocelulozno biomaso pretvorili v vredne kemikalije.
V okviru diplomske naloge smo izvajali reakcije hidrotermičnega uplinjanja slivovega lesa v pod- in nadkritični vodi, pri temperaturah 350 °C in 400 °C, brez ali v prisotnosti štirih različnih katalizatorjev (GeO2, Ni/SiO2-Al2O3, bentonit, zeolit). Dobili smo produkte v plinski, oljni, vodni in trdni fazi. Na podlagi izkoristkov posameznih faz in FTIR analiz trdnih ostankov smo ugotovili, da je do večje razgradnje slivovega lesa prišlo pri višjih temperaturah, kjer smo dobili višje izkoristke plinske in oljne faze ter nižje izkoristke trdne faze. Katalizator Ni/SiO2-Al2O3 je povzročil popolno razgradnjo slivovega lesa, z le 0,49 % izkoristka trdne faze. Ugotovili smo, da so vse plinske mešanice vsebovale H2, CO2 ter ogljikovodike C1-C6, od katerih je nastalo največ H2 in CH4. Najvišjo koncentracijo (glede na površino vrha %) vodika (80,7 %) smo določili s katalizatorjem Ni/SiO2-Al2O3 pri 400 °C. V oljnih fazah smo določili prisotnost alkanov, cikličnih spojin, aromatskih spojin, ketonov in kislin, med katerimi je nastalo največ ketonov in aromatskih spojin. HPLC analize vodnih faz so pokazale prisotnost furfuralov, med katerimi so bile koncentracije 5–MF najvišje. Najnižjo koncentracijo skupnega organskega ogljika (5,5 g/L) v vodni fazi pa smo določili pri reakciji z Ni/SiO2-Al2O3 pri 400 °C.Over-exploitation and over-reliance on fossil fuel energy has led to global climate change and atmospheric pollution. To this end, major industries have started to adopt more environmentally friendly practices that would at the same time reduce their dependence on non-renewable energy sources, which are in short supply. Lignocellulosic biomass is the most abundant and bio-renewable biomass on Earth, showing great potential to replace fossil fuels as a primary energy source. It consists mainly of cellulose (40-60%), hemicellulose (20-40%) and lignin (10-24%), which constitute a rich source of raw materials for biofuel production. Research on lignocellulosic biomass is focusing on finding alternative processes that can convert lignocellulosic biomass into valuable chemicals.
In the framework of the thesis, hydrothermal gasification reactions of plum wood were carried out in sub- and supercritical water, at temperatures of 350 °C and 400 °C, without or in the presence of four different catalysts (GeO2, Ni/SiO2-Al2O3, bentonite, zeolite). The products obtained were in gas, oil, aqueous and solid phases. Based on the yields of the individual phases and FTIR analyses of the solid residues, it was found that the higher decomposition of plum wood occurred at higher temperatures, where higher yields of the gas and oil phases and lower yields of the solid phase were obtained. The Ni/SiO2-Al2O3 catalyst resulted in a complete decomposition of the plum wood, with only 0,49 % solid phase yield. All gas mixtures were found to contain H2, CO2 and C1-C6 hydrocarbons, of which H2 and CH4 were the most abundant. The highest concentration (in % of peak area) of hydrogen (80,7 %) was determined with the Ni/SiO2-Al2O3 catalyst at 400 °C. The presence of alkanes, cyclic compounds, aromatic compounds, ketones and acids was determined in the oil phases, with ketones and aromatic compounds being the most abundant. HPLC analyses of the aqueous phases showed the presence of furfurals, among which 5–MF was the most abundant. However, the lowest concentration of total organic carbon (5,5 g/L) in the aqueous phase was determined in the reaction with Ni/SiO2-Al2O3 at 400 °C
Strength analysis of heat exchanger
No full textV magistrskem delu je predstavljen postopek trdnostne analize ploščnega tipa toplotnega izmenjevalca. Da lahko izvedemo numerični preračun po metodi končnih elementov (MKE), je potrebno pridobiti 3D model toplotnega izmenjevalca. Model ploščnega tipa toplotnega izmenjevalca je bil pridobljen s pomočjo skeniranja oz. 3D računalniške tomografije. Na podlagi pridobljene geometrije s skeniranjem je bilo potrebno le-to ustrezno popraviti, da smo jo lahko nato uporabili za numerični preračun (numerični 3D model). Geometrija je bila parameterizirana, kar nam je omogočilo izvedbo parametričnih simulacij (spremljanje različnih odzivov glede na vhodno geometrijo). V numeričnem preračunu smo se ukvarjali z obremenitvenimi primeri prelotanih in neprelotanih mest v toplotnem izmenjevalcu ter posledično z različnimi napetostno deformacijskimi stanji in njihovim vplivom na pričakovano življenjsko dobo toplotnega izmenjevalca. Numerični preračuni (MKE) so bili izvedeni v programskem paketu Ansys Workbench, pri čemer smo pridobljene rezultate analizirali ter ustrezno karakterizirali odzive glede na predhodno določene obremenitvene primere.The master\u27s work presents the process of strength analysis of a plate-type heat exchanger. In order to carry out a numerical calculation using the finite element method (FEM), it is necessary to obtain a 3D model of the heat exchanger. The model of the plate-type heat exchanger was obtained by scanning or 3D computed tomography. Based on the obtained geometry by scanning, it was necessary to correct it accordingly, so that it could then be used for numerical calculation (numerical 3D model). The geometry was parameterized, which allowed us to perform parametric simulations (monitoring different responses depending on the input geometry). In the numerical calculation, we dealt with load cases of vented and non-vented places in the heat exchanger and, consequently, with different stress-deformation states and their influence on the expected lifetime of the heat exchanger. Numerical calculations (FEM) were carried out in the Ansys Workbench software package, whereby the obtained results

Indemnity according to the rules of the agency contract in comparative law
No full textOdpravnina trgovskega zastopnika se v slovenski zakonodaji razlikuje od njene ureditve v Agentski direktivi in primerjalnopravnih ureditvah, poleg tega pa ne v teoriji ne v sodni praksi ni najti zadovoljivih odgovorov in usmeritev, kako jo pravilno razumeti in uveljaviti v praksi. Disertacija najprej obravnava zgodovino in cilje slovenske ureditve ter Agentske direktive, na kateri naj bi slovenska ureditev temeljila, nato pa tudi pravne ureditve, ki so bile izhodišče za ureditev odpravnine v Agentski direktivi. Leta 1986 je Agentska direktiva ponudila državam članicam t. i. nemško ureditev nadomestila kot eno od dveh možnosti implementacije, pri čemer se je večina držav članic odločila prav za omenjeni t. i. nemški model, Komisija pa je članicam v pomoč predlagala zgledovanje po bogati nemški teoriji in sodni praksi. Disertacija s pomočjo razumevanja Agentske direktive in zlasti primerjalnopravnih ureditev Nemčije, Avstrije, Italije in Belgije postavlja in obravnava temelje za pravilno razumevanje instituta odpravnine v slovenskem pravnem redu z osredotočanjem zlasti na njene posebnosti in razlike v primerjavi z Agentsko direktivo.
Obravnava slovenske ureditve in s tem povezane problematike se začne že pri zakonski definiciji trgovskega zastopnika, za katerega zakon zahteva opravljanje zastopanja kot registrirane dejavnosti. Nadalje je pomembno načelo pravičnosti, ki v slovenskem zakonskem določilu, ki ureja pravico do odpravnine, ni izrecno zapisano, kar pa ne pomeni, da se to načelo v zvezi z odpravnino ne uporablja. Do odstopanj od Agentske direktive prihaja tudi pri določilu, ki v izračunu najvišjega zneska odpravnine vključuje samo provizije, in ne vseh plačil, kot na primer to določajo Agentska direktiva ter primerljivi nemška in avstrijska ureditev, ter tudi pri nekaterih drugih zakonskih določilih, ki jih disertacija podrobneje obravnava. Vsekakor pa je najpomembnejša razlika med slovensko ureditvijo in Agentsko direktivo, da poleg pravice do odpravnine, ki naj bi jo trgovskemu zastopniku OZ nudil skladno z določili Agentske direktive, OZ trgovskemu zastopniku omogoča še dve dodatni pravici do odpravnine. Prva dodatna pravica do odpravnine izhaja iz drugega dela prvega odstavka 833. člena OZ, ki temelji na posebnih okoliščinah, ki naj bi terjale plačilo odpravnine, druga pa iz njegovega četrtega odstavka, ki naj bi trgovskemu zastopniku omogočil povrnitev stroškov, ki jih je imel v zvezi z uvajanjem proizvoda na tržišče, in vseh drugih stroškov, ki jih je imel zastopnik v zvezi z izvajanjem pogodbe, v primeru prenehanja pogodbe za določen čas pred potekom tega časa ali v primeru prenehanja pogodbe za nedoločen čas pred potekom petih let od sklenitve. Pri nobeni od dodatnih pravic do odpravnine pa ni treba, da bi naročitelj po prenehanju pogodbenega razmerja imel znatne koristi – še več, ne zahteva se niti, da bi trgovski zastopnik naročitelju pridobil nove stranke ali mu občutno povečal posle z dotedanjimi strankami. Gre torej za dodatni pravici trgovskega zastopnika, ki presegata minimalne zahteve iz Agentske direktive in do katerih naj bi bil trgovski zastopnik upravičen ob izpolnjevanju zakonskih pogojev, ki odstopajo od pogojev iz Agentske direktive.
Na podlagi tako zastavljenih temeljev se v nadaljevanju disertacija osredotoča na odpravnine, ki se po pravilih pogodbe o trgovskem zastopanju obravnavajo v primerjalnem pravu pri nekaterih drugih, inominatnih pogodbenih tipih, nadalje pa tudi na razmerja do odškodnine, ki jo v zvezi s pogodbo o trgovskem zastopanju opredeljujeta tako Agentska direktiva kakor tudi naše zakonsko določilo. Nič od predstavljenega v disertaciji pa ne bi imelo pravega pomena v praksi, če zaradi pogostih mednarodnih elementov v tovrstnih razmerjih ne bi bilo jasno, pred katerim organom in v kateri državi lahko trgovski zastopnik uveljavlja pravice in katero pravo se pri tem uporabi, zato predmetna naloga obravnava tudi to problematiko.The regulation of indemnity for commercial agents in Slovenian law differs from its regulation in the Agency Directive and comparative legal regimes, and there are no satisfactory answers or guidance on how to properly interpret and implement it in practice, neither in jurisprudence nor in case law. This thesis firstly discusses the history and aims of the Slovenian legislation and the Agency Directive, on which the Slovenian legislation is supposedly based, and goes on to consider the legal regimes that served as the starting point for the regulation of indemnity in the Agency Directive. In 1986, the Agency Directive offered member states the so-called German indemnity regime as one of two implementation options, with the majority of member states opting for the German model. Based on an understanding of the Agency Directive and in particular the comparative legal regimes of Germany, Austria, Italy and Belgium, this thesis sets out and discusses the foundations for a proper understanding of the institution of indemnity in the Slovenian legal system, focusing in particular on its specific features and differences as compared to the Agency Directive.
The discussion of the Slovenian regime and related issues starts with the legal definition of a commercial agent, which requires agency to be carried on as a registered activity. Also of importance is the principle of equity, which is not expressly laid down in the Slovenian legal provision governing the right to indemnity, which cannot mean in any way that the principle does not apply with regard to indemnity. There are also deviations from the Agency Directive in the provision that includes only commissions in the calculation of the maximum amount of indemnity, instead of all payments, as well as in certain other statutory provisions, which are discussed in detail in this thesis. Undoubtedly the most important difference between the Slovenian regime and the Agency Directive is that, in addition to the right to indemnity afforded to commercial agents by the Obligations Code in accordance with the provisions of the Agency Directive, the Obligations Code also affords commercial agents two additional rights to indemnity. The first additional right to indemnity is laid down in the second part of the first paragraph of Article 833 of the Obligations Code, which is based on special circumstances requiring the payment of indemnity, and the second in its fourth paragraph, which allows commercial agents to recover the costs they incurred in bringing the product to the market and any other costs they incurred in connection with the performance of the contract in the event of the termination of a fixed-term contract before the expiry of its term or in the event of the termination of an indefinite-term contract before the expiry of a period of five years from the date on which the contract was concluded. Neither of the additional rights to indemnity requires that the principal derives significant benefit from the termination of the contractual relationship – moreover, it does not even require that the agent acquires new customers for the principal or significantly increases the principal’s business with existing customers.
On the basis of the foundations thus laid, this thesis focuses in the following on indemnities that are dealt with in comparative law under the rules of the agency contract for some other, innominate contract types, and further on the relationships to compensation, which is defined in relation to the agency contract both by the Agency Directive and by our statutory provision. However, none of the information presented in the thesis would be of any actual practical relevance if, due to the frequent international elements in this type of relationship, it was not clear before which authority and in which country the commercial agent could enforce their rights and which law would apply, and the thesis therefore addresses this issue as well
Calculation of the transport line for indonesian coal in premogovnik velenje
No full textV magistrskem delu smo prikazali in preračunali verižni ter tračni transporter navpične in vodoravne izvedbe, ki sestavljajo novo transportno linijo za transport indonezijskega premoga. V izhodiščnem delu magistrskega dela je opisan posamezen transporter nove transportne linije. Preračuni odporov pri gibanju transporterjev in potrebne pogonske moči so izdelani analitično s pomočjo izrazov za preračun verižnega in tračnega transporterja. Določili smo potrebne moči posameznih transporterjev. Pri izračunu smo upoštevali podano zmogljivost, hitrost, nasipno gostoto premoga ter dolžino transporterja. Pri izdelavi numerične simulacije smo uporabili programski paket ANSYS Rocky in simulirali presipno mesto. Prikazali smo numerične rezultate masnega pretoka, obnašanje materiala, sile in napetosti nastale na tračnem transporterju.In the master thesis, we have demonstrated and calculated a chain and belt conveyors of vertical and horizontal design, which make up a new conveyor line for the transport of Indonesian coal. The initial part of the thesis describes the individual conveyors of the new transport line. The calculations of the conveyor motion resistance and the required drive power are made analytically using the expressions for the calculation of chain and belt conveyors. We have determined the required power of the individual conveyor. The calculation took into account the given capacity, speed, coal bulk density and conveyor length. We used the ANSYS Rocky software package to simulate the transfer chute. Numerical results of mass flow, material behaviour, forces and stresses on the conveyor belt are shown

Renovation of transport processes at the Megales company
No full textPodjetje Megales se ukvarja s sečnjo, prevozi, nakupom in prodajo hlodovine in lesnih sekancev. Raznovrstnost voznega parka in drugih delovnih strojev jim omogoča kar se da optimalno izvajanje dejavnosti. Področje transportne logistike zajema dnevno usklajevanje potreb po tovornih vozilih z odkupovalci lesa na terenu in razporejanje priklopnikov v skladu s pogodbami o nakupu in prodaji lesa. Pri načrtovanju transportnih logističnih procesov smo zaznali preveč praznih kilometrov, ki nastanejo, ko se tovorna vozila prazna vračajo nazaj na mesto natovarjanja, zato bomo podali ideje za povečanje števila polnih povratnih voženj. Ker so gozdarske prikolice specifične, je zagotavljanje povratnih voženj marsikdaj oteženo. Opisali bomo tudi rešitve, kako s poenotenjem voznega parka zmanjšati stroške vzdrževanja. Predlagali bomo sistem menjave prikolic in posledično zmanjšanje nepotrebnega prelaganja hlodovine. Na ta način bi privarčevali pri porabi goriva in številu ur, ki jih opravijo vozniki tovornih vozil v podjetju. Preučili bomo prednosti zaposlitve mehanika in izračunali prihranek pri stroških za vzdrževanje voznega parka.The Megales company is engaged in logging, transportation, purchasing, and selling of timber and wood biomass. The diversity of their fleet and other machinery enables them to carry out their activities as efficiently as possible. The area of transportation logistics involves daily coordination of the need for freight vehicles with wood buyers in the field and scheduling trailers in accordance with the contracts for the purchase and sale of wood. During the planning of transportation logistics processes, we have identified an issue with excessive empty kilometres that occur when freight vehicles return empty to the loading point. Therefore, we will propose to increase the number of return trips. However, providing return trips for logging trailers can be challenging due to their specific nature. We will also describe solutions for reducing maintenance costs through fleet harmonisation. We will suggest a system of trailer rotation, thus reducing unnecessary log handling. This way, we could save on fuel consumption and the number of hours worked by the company\u27s heavy goods vehicle drivers. We will look at the benefits of employing a mechanic and calculate the cost savings on fleet maintenance
Reconstruction and extension design of departments of division of internal medicine, University Medical Centre Maribor d
No full textTema magistrskega dela izhaja iz potrebe po dograditvi novih prostorov Klinike za interno medicino UKC Maribor zaradi trenutnih prostorskih pogojev, pri čemer kapacitete ne zadostujejo pogojem delovanja in nadaljnjega razvoja klinike v dejavnost poliklinike. Slednji sistem potrebuje za svoje delovanje razširjen ambulantni center in dnevno bolnišnično obravnavo s prostori za posege in diagnostiko. Sedaj deluje v okrnjeni obliki. Poleg tega trenutni prostorski pogoji in vedno pogostejše oblike bolezni prebivalstva ne zagotavljajo primernih procesov v načinu pristopa k bolniku na intenzivnem internem oddelku, kjer se bolniki z različnimi infekcijskimi in neinfekcijskimi stanji zdravijo v skupnih bolniških sobah. Poleg tega sedanja zasnova oddelka ne zagotavlja optimalnih pogojev dela osebja, njihova varnost pa je minimalno zagotovljena. To lahko pripisujemo primanjkovanju določenih osnovnih prostorov za delo in počitek, med katerimi še najbolj izstopajo primanjkovanje potrebnih filtrov za osebje pred posamezno bolniško sobo, posteljnih filtrov in primerne nadzorne postaje z zagotavljanjem konstantnega pogleda na bolniške sobe. Na podlagi izpostavljenih največjih problematik na kliniki se v magistrskem delu poglobimo v raziskovalni del, kjer preučimo demografske spremembe s področja zdravstva, razločimo osnovno terminologijo s tega področja in se poglobimo v študije vplivov bolniškega okolja na počutje in okrevanje pacienta ter delovanje in regeneracijo osebja. Poleg tega preučimo primere sodobnih bolnišnic na evropski in svetovni ravni in naredimo zgodovinsko analizo razvoja bolnišnic in analizo zgodovinskega razvoja mariborske bolnišnice oziroma UKC Maribor. Nadaljujemo z arhitekturno analizo ožjega območja UKC Maribor in analizo ter študijo Klinike za interno medicino, kar nam poleg raziskovalnega dela predstavlja kot osnovo za nastavitev koncepta nadaljnjega razvoja klinike, širitve in rekonstrukcije. S številnimi prikazi in načrti predstavimo rešitev sedanje problematike, s katero se sooča Klinika za interno medicino.The topic of the master thesis arises from the need to upgrade the new premises of the Division of Internal Medicine of University Medical Centre Maribor due to the current space conditions, where the capacities are insufficient for the operation and further development of the Clinic into a Polyclinic. The latter system needs an expanded outpatient centre and a day hospital with facilities for interventions and diagnostics. It now works in sip form. In addition, the current spatial conditions, and the increasing prevalence of diseases in the population do not ensure adequate processes in the way patients are approached in the ICU, where patients with various infectious and non-infectious conditions are treated in shared patient rooms. In addition, the current design of the department does not ensure optimal working conditions for staff and their safety is minimally guaranteed. This can be attributed to the lack of certain basic facilities for work and rest, the most notable of which are the lack of the necessary filters for staff in front of each patient room, bed filters and a suitable monitoring station with a constant view of the patient rooms. Based on the major issues highlighted in the clinic, the master\u27s thesis delves into the research part of the project, where we examine demographic changes in the health care field, distinguish basic terminology in the field, and delve into studies of the impact of the hospital environment on patient well-being and recovery, as well as on staff performance and regeneration. In addition, we look at examples of modern hospitals at European and global level and make a historical analysis of the development of hospitals and an analysis of the historical development of Maribor Hospital or now named University Medical Centre Maribor. We are following up with an architectural analysis of the immediate area of the University Medical Centre Maribor and an analysis and study of the Division of Internal Medicine, which, in addition to our research work, provides us with a basis for setting the concept of further development, expansion and reconstruction of the clinic. We present a solution to the current problems facing the Division of Internal Medicine, with several diagrams and plans

Glavni cilj dela je bil izdelati 3D-animacijo, ki je ponazarjala realističen proizvodni proces in služila kot učni pripomoček pri uvajanju zaposlenih. S tem smo prikazali, kako lahko digitalne 3D-simulacije prispevajo k učinkovitejšemu, varnejšemu in bolj stroškovno ugodnemu izobraževanju zaposlenih. V teoretičnem delu smo predstavili ključne tehnologije, koncepte in razvoj digitalnih orodij za industrijsko usposabljanje, v praktičnem delu pa smo v programu Blender zasnovali in izdelali 3D-model proizvodne linije z animacijo ključnih korakov sestave. Animacija omogoča jasno vizualizacijo posameznih postopkov in varno učenje brez fizične izpostavljenosti strojem ali nevarnim okoljem. Dodatno smo izvedli raziskavo, s katero smo preverili uporabnost ustvarjene animacije v primerjavi s klasično dokumentacijo. Rezultati so pokazali, da 3D-simulacije pozitivno vplivajo na razumevanje delovnih nalog, povečujejo ohranjeno znanje in zmanjšujejo število napak. Na podlagi ugotovitev smo pripravili priporočila za uvajanje tovrstnih rešitev v industrijsko izobraževanje in smernice za izboljšanje digitalnih vsebin s pomočjo odprtokodnih orodij.In this thesis, we explored how the open-source software Blender was used to simulate manufacturing processes for the purpose of training industrial workers. The main objective of the thesis was to create a 3D animation that represented a realistic production process and served as an educational tool for employee onboarding. Through this, we demonstrated how digital 3D simulations could contribute to more efficient, safer, and more cost-effective employee training. In the theoretical part, we presented key technologies, concepts, and the development of digital tools for industrial training, while in the practical part, we designed and created a 3D model of a production line in Blender, including animations of the key assembly steps. The animation provided a clear visualization of individual procedures and enabled safe learning without physical exposure to machinery or hazardous environments. Additionally, we conducted a study to evaluate the usefulness of the created animation in comparison with traditional documentation. The results showed that 3D simulations had a positive effect on understanding work tasks, increased knowledge retention, and reduced the number of errors. Based on these findings, we prepared recommendations for the implementation of such solutions in industrial education and guidelines for improving digital learning materials using open-source tools
