No full textGenerativna umjetna inteligencija (GAN) ključni je alat u logistici, koristeći algoritme strojnog učenja za generiranje novih podataka sličnih onima korištenim za treniranje. GAN omogućava stvaranje realističnih podataka koji nisu prisutni u izvornom skupu podataka, što je korisno u logistici. Primjena GAN-a donosi brojne prednosti, poput optimizacije skladištenja i distribucije, što omogućuje učinkovitije upravljanje zalihama i smanjenje troškova. Također, GAN se koristi za optimizaciju logističkih ruta, smanjujući vrijeme i troškove transporta. U predviđanju potražnje, GAN omogućuje preciznija predviđanja temeljena na analizi trendova i povijesnih podataka, što pomaže u prilagodbi strategija upravljanja zalihama. GAN poboljšava učinkovitost identificiranjem obrazaca u potražnji i dinamičkim prilagođavanjem zaliha, smanjujući rizik od viška ili manjka zaliha. Korištenjem GAN-a poduzeća bolje komuniciraju s dobavljačima i prilagođavaju svoje ponude. Unatoč izazovima implementacije, GAN ima velik potencijal za transformaciju logističkih operacija, čineći ga ključnom tehnologijom budućnosti.Generative Artificial Intelligence (GAN) is a powerful tool in logistics, using machine learning to generate new data similar to the original set. This ability makes GAN valuable for optimizing storage, reducing costs, and improving goods flow. It also aids in route optimization, decreasing transport time and costs. Accurate demand forecasting is vital for logistics. GAN enables better predictions based on trends and historical data, allowing companies to adjust production and inventory strategies. It supports effective inventory management by identifying demand patterns and dynamically adjusting stock levels, reducing the risk of shortages or excess. Additionally, GAN improves supplier communication by offering insights into market needs, enabling suppliers to adjust their offerings accordingly. Despite implementation challenges, GAN’s potential to optimize processes, forecast demand, manage inventory, and enhance supplier relationships positions it as a key technology for the future of logistics

No full textOvom završnom radu cilj je opisati tehnologije autonomne vožnje uključujući njezin način rada, komponente, ulogu vozača, kao i pregled prilika i izazova povezanih s autonomnim vozilima. U početku se opisuje povijest, razvoj i porijeklo autonomnog vozila, kao i početni koncepti iza takvog vozila. Slijedi definicija pojma autonomnog vozila uz objašnjenje trenutnih razina automatizacije. Posebna pažnja posvećena je ugrađenim pametnim sustavima i uređajima, koji omogućuju vozilu da se samostalno kreće predviđenom rutom, poštujući sva pravila vožnje. Raspravlja se o zakonskoj regulativi i zakonima koji se odnose na autonomnu vožnju jer je ova industrija relativno nova i podložna stalnim izmjenama zakona. Komunikacijski sustavi su bitan dio ove teme jer s pomoću njih vozilo komunicira s okolinom (pješaci, infrastruktura, vozila) te su stoga sastavni dio sigurnosti na cesti. Zaključak je da će se cijela automobilska industrija, s godinama, sve više okretati prema razvoju autonomnih vozila, a kompanije poput Googlea i Amazona već ulažu u razvoj potpuno autonomne robotaksije taksije Waymo i Zoox.This final paper aims to describe the technologies of autonomous driving including its functioning, components, the role of the driver, as well as an overview of the opportunities and challenges associated with the autonomous vehicles. Initially, the history, development, and origin of the autonomous vehicle are outlined, so are the initial concepts behind such a vehicle. Definition of the term autonomous vehicle follows along with the explanation of the present levels of automation. Special attention is given to the embedded smart systems and devices, that enable the vehicle to move independently along the forecasted route, respecting all driving rules. Legal regulations and laws related to autonomous driving are discussed, as this industry is relatively new and subject to constant changes in the law. Communication systems are an essential part of this topic because the vehicle communicates with the environment (pedestrians, infrastructure, vehicles), therefore they are an integral part of the road safety. The conclusion is that the entire automotive industry will, over the years, turn more and more towards developing autonomous vehicles, and companies such as Google and Amazon are already investing in fully autonomous robotaxis Waymo and Zoox

Rail transport in practise : (case study: rail cargo logistics)
No full textŽeljeznički promet je usko povezan sa otpremništvom. Može se okarakterizirati kao složeni dio prometne grane, a otpremnička djelatnost kao kompleksna. Stoga, jedno ne bi moglo funkcionirati samostalno bez drugog. Povećana uporaba željeznice pridonijela bi boljoj kvaliteti života, tj. bilo bi znatno manje zagađenja nego drugim oblicima prometa. Također, željeznica stvara manja zagađenja po količini prevezenog tereta. Primjerice, prilikom otpreme jednog kontejnera iz Kine do Rijeke uštedi se otprilike 1.040 kg CO2. U ovom radu je obrađena uloga otpremništva, odnosno logistike u organizaciji željezničkog prijevoza dobara (kontejnera) kao i uska povezanost sa samim prijevozom. Detaljno je objašnjen djelokrug poslovanja logistike – svi potrebni koraci u organizaciji prijevoza na primjeru poslovanja firme Rail Cargo Logistics – Croatia d.o.o.Railway traffic is closely related to fright forwarding. It can be characterized as a complex part of the transport branch as well as freight forwarding. Therefore, one could not function independently without the other. Increased use of the railway would contribute to a better quality life, i.e. there would be singificantly less pollution. Also, railway creates less pollution per amout of transported cargo. For example, when shipping one container from China to Rijeka, approximately 1,040 kg of CO2 is saved. This paper shows the part of freight forwarding, i.e. logistics in the organization of rail transport of goods (containers) as well as the close connection with the transport itself. The scope of logistics is explained in detail – all necessary steps in organization of transport are explained in detail using the example of the buisness of the company Rail Cargo Logistics – Croatia d.o.o

Financing of new cruise ship constructions with a focus on the ship “Scenic Eclipse II”
No full textDa bi brodarske kompanije ostale konkurentne na tržištu, neprestano moraju unaprjeđivati svoje usluge, osoblje i tehničku infrastrukturu, uključujući flotu brodova. U tome im pomažu stručni kadrovi, analize, vlastiti kapital i financijska sredstva, kao i mogućnost zaduživanja radi ostvarenja ciljeva, primjerice nabavke novih brodova. Različiti oblici zaduživanja uključuju kredite, leasing, bilančno financiranje i financiranje iz javnih izvora. Svaki od tih načina ima svoje prednosti i mane kako za primatelja tako i za davatelja pozajmice. Da bi se to pobliže dočaralo uzet je primjer Firme „MKM YACHTS d.o.o.“ koja je uz pomoć Riječkog brodogradilišta „3.MAJ“ napravila najluksuzniji polarni ekspedicijski kruzer na svijetu „Scenic Eclipse II“.To remain competitive in the market, shipping companies must continuously improve their services, staff, and technical infrastructure, including their fleet of ships. They are aided in this endeavor by skilled personnel, analyses, their own capital, and financial resources, as well as the option to borrow funds to achieve their goals, such as acquiring new vessels. Various forms of borrowing include loans, leasing, balance sheet financing, and financing from public sources. Each of these methods has its own advantages and disadvantages for both the borrower and the lender. To illustrate this more closely, consider the example of the company "MKM YACHTS d.o.o." which, with the assistance of the Rijeka Shipyard "3.MAJ", built the world's most luxurious polar expedition cruise ship, the "Scenic Eclipse II"
