The risk rate by ADR road transport of dangerous matters
Brožová, Pavlína
2010 - anglický
The paper will be focused on the questions of ADR road transport of dangerous matters, especially on the risks estimation of transport of dangerous goods in the Czech Republic. The risks estimation is the basic presumption for safety increment by this type of risk transport. The aim of the paper is to refer to the risks, which may occur not only in the case of traffic accidents, but also by influence of the various logistics activities. There is also an endeavour to minimization of these risks in the paper.

The technological model of operating area by the combined transport
Cempírek, Václav; Široký, Jaromír; Císařová, Hana
2010 - anglický
The contribution deals with design technology service model using the combined transport.
It assesses the performance indicators in relation to price and quality of services provided and on this basis decides on the type of the transport. This is the decision-making processes, which should answer the question, whether used directly in road freight transport, direct rail freight transport or combined transport. In this contribution is the combined transport meant as a system between the conventional modes, which are transhipped goods from road vehicles to the rail cars or river boats.

Electric automobil - wishes and reality
Duchoň, Bedřich; Opava, Jaroslav
2010 - anglický
The demands on cars energy resources are given by the following items: power, speed, acceleration, operation range. All these factors are under balance: future wishes and contemporary reality.
The proposal is dedicated to the analysis of demands related to the electric automobiles.
As a hopefulness solution of these transport means can be seen for city transport (forwarding, shopping, postal services etc). The technical and economic approaches are discussed, too.

Economic aspects of purchasing logistics
Hruška, Roman
2010 - anglický
The article deals with economic aspects of purchasing logistics. Purchasing department
in the company must manage and reduce costs if it is possible. The purchaser can use a number
of methods to reduce administrative costs, purchase prices and inventory carrying costs. From a point of view of economics is the main aim of purchase to reduce costs related to purchasing activities. Purchasing focused on getting the right product or service to the right place at the right time, in the right quantity, in the required condition or quality, and from the right supplier at the right price. The management of purchasing activities can lead to increased profitability.

Evaluating and ranking infrastructure manager strategies using the combined AHP/DEA method
Kecman, Pavle; Jovanović, Predrag; Bugarinovic, Mirjana
2010 - anglický
Restructuring of European Railway companies has resulted in creating new subjects within railway
systems - infrastructure managers (IM) on the one hand and railway operators on the other. Each of these subjects strives for efficient operation within the boundaries dictated by regulatory bodies or government directly. In this paper we examine the efficiency and rank different business strategies of railway infrastructure managers using combined AHP/DEA method. Different strategies include different number of paths allocated (diferent capacity utilization index), different ratio of paths allocated to passenger
and freight trains in case of demand for paths being higher than the capacity of the line and infrastructure access charges based on different principles. Each strategy examined is subjected to constrains such as the maximum capacity of the line and public service obligation considering the obligatory number of passenger trains in the timetable defined by the public authorities. The method applied for evaluating and ranking different strategies is a combined AHP/DEA method. Each strategy of the IM is regarded as a decision making unit (DMU) and as such, in the first stage of the model, paired with each of the remaining DMU’s. The Data Envelopment Analysis (DEA) is run for each pair of units separately. In the second stage, the pair wise evaluation matrix generated in the first stage is utilized to rank scale
the units via the Analytical Hierarchical Process (AHP). The results can be used for evaluation of efficient use of infrastructure capacity and financial efficiency of IM simultaneously.

Application of tribodiagnostics in the maintenance of vehicles
Machalíková, Jaroslava; Sejkorová, Marie; Chýlková, Jaromíra; Schmidová, Eva
2010 - anglický
Tribotechnical diagnostics use lubricants as media that help obtain information about processes and changes in the systems that they lubricate. If tribodiagnostics are applied properly and thoroughly, they result in significant savings in many areas; for example, they contribute to an increase of the lifetime of vehicles as well as other machines and devices, to a decrease of consumption of energy, to limiting the idle time due to failures and subsequent repairs, to a decrease of investment as well as operational costs (especially the machine maintenance and repair costs), to an increase of the safety of operation and to a reduction of negative influences of transport on the environment. They are based on monitoring the course of progressive wear of lubricants as well as mechanical parts.
The paper deals with possibilities of using modern instrumental methods in particular: infrared
spectrometry with Fourier transformation, analytical ferrography with consequential image analysis, scanning electron microscopy, local electron microanalysis and voltametry in the area of vehicle lubricant analysis. The first part of the paper presents the results of a study of the course of wear of engine, gear and hydraulic oils and plastic lubricants used for lubricating the vehicle parts. The second part of the paper deals with the abrasion particles isolated from oil filters in different types of vehicles. The evaluation of their number, size, shape, colour, surface characteristics and other morphological attributes helps obtain information about the part they come from and about the mechanism of their creation. This knowledge can thereafter contribute (especially in connection to the knowledge of the chemical structure of the particles) to an elimination of the hazard of a damage or a
breakdown of the machine. The combination of the methods presented above helps monitor the evaluation of the course of processes related to the wear of particles of vehicles as well as steady mechanisms and obtain its complex evaluation.

Vehicle scheduling with heterogeneous bus fleet
Palúch, Stanislav; Peško, Štefan
2010 - anglický
The paper studies vehicle scheduling problem formulated as to minimize the number of vehicles with several types of buses. A general mathematical model is presented using graph coloring and bivalent linear programming formulation. A suboptimal algorithm is designed and the way is proposed how to exploit its result to reduce the corresponding bivalent linear programming model.
