Intellectual capital - developmental resource of logistic companies for the 21st century
Ratko Zelenika, Drago Pupovac, 2003, pregledni znanstveni članek

Opis: On the basis of relevant scientific research this paper systematically and concisely elaborates the interaction between intellectual capital and logistic services production. Full attention is given to intellectual capital as a factor in effective creation of the logistic processes or in other words, to prove the statement that the first place for achieving competitive advantages in the global and/or regional market of logistic services belongs to knowledge used to produce or improve the existent logistic systems and to create new ones.Further, the paper deals with the tasks of creative logistic managers as open, dynamic and stochastic systems based on knowledge or the creation of universal logistic model determined by the fact that intellectual capital and technological paradigm create the way to new logistic paradigm.Special attention is paid to building and presenting a mathematical model for measuring the intellectual capital as well as the success of its use in different logistic companies.

Influence of modern cableways on the development of mountain tourist centres
Sergej Težak, Ivan Mavrin, Ivo Jurić, 2005, kratki znanstveni prispevek

Opis: The paper studies the problem of constructing cableways with advanced technology and their influence on the operation and development of cableway companies from several aspects. Modern cableways with detachable grips enable faster carriage of passengers. They have the possibility of transporting more passengers over the same distances. Recently, this trend of introducing modern cableways has been particularly present in chairlifts which carry skiers. Such chairlifts with detachable grips allow transport of skiers over greater distances and therefore must have respective ski slopes covering wider areas which in turn affects the expansion of the mountain tourist centres. The chairlifts with detachable grips require more knowledge and personnel to manage and maintain them, as well as more investment capital.

Incorporation of duffing oscillator and Wigner-Ville distribution in traffic flow prediction
Anamarija L. Mrgole, Drago Sever, 2017, izvirni znanstveni članek

Opis: The main purpose of this study was to investigate the use of various chaotic pattern recognition methods for traffic flow prediction. Traffic flow is a variable, dynamic and complex system, which is non-linear and unpredictable. The emergence of traffic flow congestion in road traffic is estimated when the traffic load on a specific section of the road in a specific time period is close to exceeding the capacity of the road infrastructure. Under certain conditions, it can be seen in concentrating chaotic traffic flow patterns. The literature review of traffic flow theory and its connection with chaotic features implies that this kind of method has great theoretical and practical value. Researched methods of identifying chaos in traffic flow have shown certain restrictions in their techniques but have suggested guidelines for improving the identification of chaotic parameters in traffic flow. The proposed new method of forecasting congestion in traffic flow uses Wigner-Ville frequency distribution. This method enables the display of a chaotic attractor without the use of reconstruction phase space.

Development harmonisation of mountain resorts ropeway and tourist infrastructures in the Republic of Slovenia
Drago Sever, 200, kratki znanstveni prispevek

Opis: Operation efficiency of mountain resort systems depends largely on harmonious operation of the most important and therefore most influential elements of ropeway transportation and tourist subsystems. Within the framework of a tourist subsystem, the extent and quality of tourist offer for long-staying guests plays an essential role. Harmonised development of the above-mentioned elements ensures major utilisation and better economic management of the entire system so that it may offer quality services. First of all, the system enables permanent and environmentally friendly development of the systems that are as a rule in an absolutely sensitive alpine region. The article deals with some results of in-depth research on the ropeway transportation system and the results of know-how transfer into the actual environment of the Slovenian mountain resorts.

Freight transport innovations of European railways - new market chances and technological perspectives
Stanislav Božičnik, Konrad Schliephake, 2005, pregledni znanstveni članek

Opis: The paper analyses the main technical and economic elements of the current European rail freight market and presents the basic concepts of possible new technologies in the rail freight system. They would enable the railways to enter the more rewarding niches of the freight transport market. In an attempt to understand better the problems of introducing innovations into the transport sector this paper also considers the theoretical framework and analyses the implementation paths of the proposed technological innovations. New technologies are confronted with various barriers and difficulties created by the existing and dominant technological paradigms. These are often powerful enough to prevent the introduction of alternatives and promising innovations. The empirical part of the paper focuses on the possibilities of combining the existing innovative rail freight technologies which could, with the appropriate organizational solutions (time-tables) and political support, increase the competitiveness of the rail freight transport in new and promising market segments.

Dynamic optimization in supply chains
Drago Pupavac, Jasmina Pašagić Škrinjar, Ratko Zelenika, 2007, izvirni znanstveni članek

Opis: Production and stock optimization in supply chains is a complex problem because it determines the optimum quantity production in time. Due to their multileveld nature, those problems are mostly solved by different methods and models of dynamic programming. The problem discussed in this paper refers to the determination of optimum quantity of production and stocks within the supply chain in a certain period of time, as well as in each sub-interval of a period, but with the condition that the production and stock expenditure remains minimal and that the predetermined demand in every sub-interval and throughout the entire observation period remains satisfied.

Dimensioning of signalized intersections in realistic urban environment
Matej Dobovšek, Drago Sever, 2005, pregledni znanstveni članek

Opis: It is very complex to assure the dynamics of traffic networkin urban environment because of the intensity of traffic flowsand the limited space in the urban area. Signalized intersectionsare undoubtedly very important and frequent element inroad traffic network in urban regions, which greatly influencesthe traffic flow dynamics on each section as in the whole trafficnetwork. The time (delay) a vehicle needs to drive through anintersection directly influences the travel comfort, fuel consumption,traffic pollution and so on. There are many methodsfor dimensioning signalized intersections in the world literature.One of the most applied methods is the HIGHWAY CAPACI1YMANUAL (HCM) 2000 which is based on competentinput traffic flows and other characteristics of traffic signalregulations. The intention of this paper is to establish whetherwe can use the HCM 2000 method directly in the Slovenian realenvironment. Based on the established methodology of researchand limited number of delay measurement in real environmentintersections, there have been some deviations. Thecompletion of the level of service criterion for signalized intersectionshas been proposed, with the intention for more suitabilityestimation in the realistic environment.
