1. Geographical information system modeling for planning internal transportation in a manufacturing plant’s outdoor areaKlemen Prah, Brigita Gajšek, 2024, original scientific article Abstract: A geographical information system (GIS) is an advanced tool for collecting, managing, and analyzing spatially-referenced data. The contribution of GIS use to process performance indicators can be improved by combining it with multi-criteria decision analysis (MCDA). Combining a GIS and MCDA is, in the scientific literature, rarely discussed for planning an internal transportation system in a manufacturing plant’s outdoor area. The purpose of this article is to clarify what mangers can expect from using a combined approach when deciding on a transport fleet and the operational routing of vehicles. Beside the simulation of MCDA, the computer software ArcGIS Pro 3.0.2 with the Network Analyst extension was used for modelling the transportation system in the form of a case study. The article demonstrates the feasibility and effectiveness of GIS and MCDA use and reveals the extent of the challenge of how decision makers could make the most of ArcGIS functionality. The final solution for an internal transportation system in a manufacturing plant’s outdoor area includes such a vehicle fleet and the set time windows of orders for transport services, so that there are no violations of time windows and the work is completed within the work shift while minimizing costs, time, and distance. Decision makers can use the program without advanced knowledge of optimization approaches, following a procedure that does not differ much from that of learning to use other business software tools. On the contrary, the listed disadvantages can be summarized as the rigidity of setting detailed boundary conditions for a specific simulation scenario.

2. Road freight transport forecasting : a fuzzy Monte-Carlo simulation-based model selection approachDejan Dragan, Simona Šinko, Abolfazl Keshavarzsaleh, Maja Rosi, 2022, original scientific article Abstract: As important as the classical approaches such as Akaike's AIC information and Bayesian BIC criterion in model-selection mechanism are, they have limitations. As an alternative, a novel modeling design encompasses a two-stage approach that integrates Fuzzy logic and Monte Carlo simulations (MCSs). In the first stage, an entire family of ARIMA model candidates with the corresponding information-based, residual-based, and statistical criteria is identified. In the second stage, the Mamdani fuzzy model (MFM) is used to uncover interrelationships hidden among previously obtained models criteria. To access the best forecasting model, the MCSs are also used for different settings of weights loaded on the fuzzy rules. The obtained model is developed to predict the road freight transport in Slovenia in the context of choosing the most appropriate electronic toll system. Results show that the mechanism works well when searching for the best model that provides a well-fit to the real data.

6. New feeder line rail freight paradigm for the European railwaysStanislav Božičnik, 2006, other scientific articles Abstract: The article deals with the development of the new paradigm of the European rail freight system predominantly suitable for the feeder lines (market niches). Taking into consideration the so far adopted legal solutions of the EU Commission for internationalisation (liberalisation) of the European railway system, the concept of the new rail freight model was developed in order to contribute to the increase of the quality, as well as to the growth of the volume of the rail freight services in Europe. Based on the findings about the disadvantages of the existing rail freight paradigm, the new solution consisting of the three interrelated and interconnected subsystems: institutional, technical/technological and organisational, is proposed. New liberalised access to the entire European rail infrastructure network will increase the competition and most probably attract new railway freight service providers. The introduction of the suggested innovative solutions in form of small, self-propelled, bi-directional train formation that can be automatically coupled and decoupled and equipped with the innovative loading and unloading equipment (enabling loading/unloading operations wherever the truck can stay parallel to the train), is to be expected predominantly on the feeder lines (market niches) of the European railways.

7. Model of sustainable growth and development of the cableway transport system in SloveniaSergej Težak, Ratko Zelenika, Drago Sever, 2011, original scientific article Abstract: The cableway transport system is very important for the Slovenian tourist economy. Within the Slovene transport system, the cableway transport subsystem has a specific role because it allows and ensures access to regions which are difficult to access or completely inaccessible by other transport subsystems owing to the configuration of the area. The quality and development of transport services are directly linked to the introduction of new cableways. New technical achievements, which are nowadays used in cableways, all provide greater capacity and higher speed of cableways, which, however, results in their higher maintenance and exploitation costs.
The cableway transport system is being developed in Slovenia, but not on principles of sustainable development. This paper presents a model of sustainable growth and development of the cableway transport system in Slovenia based on which it is possible to determine assumptions for future growth so that the Slovene cableway transport system would approach standards of such highly developed systems. The new model includes ten essential elements of this system for which growth rates were calculated.

8. Selection of warehouse-transportation vehicles using discrete simulationsMatjaž Šraml, Tone Lerher, Grega Ljubej, 2008, published scientific conference contribution Abstract: In this paper four different types of warehousingtransportation vehicles (lifttrucks and stacker crane) are analyzed. The complexity of designing warehousing systems in an analytical way is high; therefore the discrete simulation models were performed in order to gain the basic data for different types of warehousing-transportation vehicles. First, the counter balance lift truck is analyzed, which is useful for a lower rack warehouse construction and a lower frequency of operation. Next, the reach truck is analyzed; it enables to achieve higher lifting places, with a relatively high frequency and lift capacity. The narrow aisle lift truck can reach heights up to twelve meters, and is suitable for high frequency demands and lift capacities. Finally, the automated storage and retrieval system is analyzed. The presented models prove to be a very useful and flexible tool for choosing a particular type of warehousing system on the first stage of designing the warehouse process.
