Communications - Scientific Letters of the University of Zilina 2016, 18(2):26-29 | DOI: 10.26552/com.C.2016.2.26-29
An important factor in choosing the transport mode in the automotive industry is not only the current price but also the shipping time. In some cases the latter one is even crucial and significantly affects the choice of the transport mode. Geographical location of the port of Bratislava allows its direct connection to the North and Black Sea. The study provides a comparison of transportation time from the selected Slovak car producers and shows advantages of water transport. Time of delivery is a criterion that can be easily quantified and mutually compared. The fastest transportation mode - the road transport saves the time of delivery eight times...

We searched for the impact of transport and logistics on exports using transaction dynamics as described by Coase and Williamson. We deal with the costs of exchange using international sales contracts where the traditional calculation structure, based primarily on costs of delivery is extended with transaction costs. Furthermore, we measure the impact of such adjusted costs of exchange on the added value using Porter's methods and determine which costs have the nature of investment. Finally, the effect of resource implementation into information and communication technologies...

This paper deals with operational effectiveness of large container carriers transporting standardized transportation units. The calculation is related to costs per one TEU transported. What is a very important factor in maritime transport is the vessel's speed. Speed has a considerable influence on total costs, and that's why this factor is also taken into consideration in the calculation. Besides speed, there is another important factor, i.e. the utilization of the capacity of container ships, and that's why new container ship types (Suezmax and Triple-E) were considered in the calculation. In the conclusion, other factors are stated that are of importance...

Climatologists constantly point to the change of the climate on Earth. They consider CO2 emissions to be one of the main causes of these changes. Transport is significant producer of the greenhouse gases. If one litre of gasoline is burnt, 2.5 kg of CO2 is released into environment. Incineration of one litre of oil means that the air gets 2.7 kg of CO2 [1]. Moreover, the air gets other pollutants, particularly nitrogen oxides NOx, unburned hydrocarbons, particulates. If we want to stop or delay the climate change, we should minimize production of the greenhouse gases. This objective could be implemented through legislation, designing of more efficient...

Critical Infrastructure Designation in European Union Countries: Implementation of Systems Approach
Petr Novotny, Jiri Markuci, David Rehak, Ibrahim Almarzouqi, Lucia Janusova
Communications - Scientific Letters of the University of Zilina 2016, 18(2):163-169 | DOI: 10.26552/com.C.2016.2.163-169
The contribution deals with the issue of designating critical infrastructure elements in European Union Countries. Based on approach analysis in selected countries, where sufficient attention is paid to the area of critical infrastructure, the aim of the article is to propose a systems approach to critical infrastructure designation. The aim is determined by the fact that a significant number of EU countries do not currently apply the systems approach and designating of elements is realized via sectors approach, i.e. without taking possible bonds with other sectors into consideration. Therefore, using the systems approach may be a solution to realizing...
