This paper studies a novel autonomous vehicle-based storage and retrieval system (AVS/RS) design with movable lifts (AVS/RS/ML). In the proposed system, there are aisle-captive lifts that are able to travel along the warehouse aisle to position themselves at the target column location. Those lifts can lift up/down the autonomous vehicles to/from the target storage compartment when they are in standstill. This novel design is proposed as an alternative to existing AVS/RSs to balance the resource utilizations as well as to provide an inexpensive solution with highly utilized autonomous vehicles (i.e., AGVs). As an initial work, for this novel system, two alternative operating designs under different racking configurations are experimented. We compare those two designs by their throughput rate performance metrics under the arrival rate scenarios with highly utilized AGVs (i.e., 95%). Besides, we experiment with two warehouse capacity scenarios: 900 and 1800 storage compartments. The results show that designs with two separate I/O point locations provide a better throughput rate than designs with single I/O point location. Besides, a decreased number of columns in the system improves the system’s performance.

Traffic growth is strongly fuelled by economic growth, because without an efficient transport system the internal market and the globalization of trade cannot fully be exploited. The growth of traffic is affected primarily by two factors, namely in the passenger traffic by the increased use of cars, whereas in freight transport the traffic growth was affected by changes in the economy. The economic growth will lead to increased need for mobility it is estimated that demand will increase by 38% for freight transport services and by 24% for passenger transport (European Commission, 2001).

V diplomskem delu predstavljamo pomen transportnih storitev za gospodarstvo, ki v svetu naraščajo. Globalizacija je poleg večjega trga prinesla tudi večjo konkurenco. Podjetje je lahko uspešno samo s celovitim nadzorom stroškov. V prvem delu predstavljamo vrste transporta s poudarkom na cestnem transportu ter posebnimi oblikami transportnih sistemov. Sledi opredelitev transportnih stroškov. Drugi del je namenjen predstavitvi transportne dejavnosti v podjetju Transport Pušnik, d.o.o., kjer so z uvedbo programa za sledenje izboljšali svoje poslovanje. This thesis presents the importance of transport services in the economy and its increasing role in the world. Globalization brings with bigger market also more competition . The company can only be successful with the full cost control . In the first part we present modes of transport with a focus on a road transport and the specific forms of transport systems .Next is the definition of transport costs . The second part is dedicated to the transport activities of the company Tranport Pušnik, d.o.o., where they have improved their business with the use of program for tracking.

V uvodnih delih diplomskega dela so podrobneje opisane zahteve za izdelavo, oziroma zasnova linije za pakiranje dimljenih rib glede na pregled stanja konkurence obravnavanega področja. V osrednjem delu diplomskega dela je prikazan tok materiala in postavitev delovnih mest s konstrukcijskimi rešitvami, vključno s preračunom trakov. V zaključku naloge je predstavljena možnost modularne zgradbe in izdelave tehnične dokumentacije. Diploma work with a title Construction of a smoked fish packing line includes the whole process from analysing technological and flow demands to manufacturing the production line for smoked fish packing. In the preface of this diploma work there are in detail described demands for manufacturing, respectively design of a smoked fish packing line due to competition state overview. The material flow and workplace settings with construction solutions including the belt calculations are represented in the central part. The possibility of modular construction and the making of technical documentation is presented in the conclusion.
