Nowadays, transport companies operate in a constantly changing environment and are exposed to various risks. One of the main problems of the carriers is the difficulty in obtaining payment for the provided services. The purpose of this article is to assess the scale of debt recovery problem in the Polish transport companies. The publication characterizes main reasons of the occurrence of delays in payments and describes the most effective methods of debt recovery. The article provides us with th(..)

ANALYSIS OF THE TRAFFIC INTENSITY OF CARGO VEHICLES IN
THE BORDER POINTS

Velizara PENCHEVA/ Asen ASENOV/ Dimitar GROZEV/ Rositsa A rhangelova@uni-NGELOVA/ Ivan GEORGIEV

The present work reviews the border checkpoints in Bulgaria and their work for one year. On the basis of collected information, the seasonal inconsistency of work at the border checkpoints is assessed and their work is modeled as a mass service system (queuing system or theory) to assess capacities to a specific point in the existing infrastructure and organization of work. Capacity of border crossing point is defined as the time for stay of heavy goods vehicles at different incoming flows as we(..)

THE DISTRIBUTION OF MARSHALLING WORK OF INDUSTRIAL AND MAINLINE RAIL TRANSPORT

Andrey BORODIN/ Vitaly PANIN

The article discusses the issue of effective distribution of work on formation of train network between the stations of industrial and mainline rail transport. The analysis is worked out of difficulties in the interaction of technological systems of railway transport of common and uncommon use and risks of the transport stream delays. The strategy for sorting of wagons and a complex of interconnected mathematical models is developed. The proposed solution method is based on step-by-step distribu(..)

SIMULATION MODEL FOR MARITIME CONTAINER TERMINAL

Florin RUSCĂ/ Mihaela POPA/ Eugen ROȘCA/ Mircea ROȘCA/ Aura RUSCĂ

For logistic chains that have a maritime component, the ports transition involves a set of specific operations inside maritime container terminals. This can be cargo handling operations from the terrestrial vehicle in the storage area of ports, from port storage area in the maritime ships, as well as storage operations in the port area and other container terminal activities. Taking into consideration the multi-flow interactions and the non-uniform arrival of vessels and in-land vehicles, discre(..)

SPECIFICATION OF A LOCATION FOR OPTED PORT LOGISTICS CENTER IN A GIVEN AREA USING THE METHOD OF OPERATIONAL RESEARCH

Jiří KOLÁŘ/ Ondrej STOPKA/ Srećko KRILE

This paper is focused on area identification to find a proper location for the specific port logistic center in a certain territory by applying the particular method of operational research. Graph theory offers a useful tool for solving such problems in transportation infrastructure development. The type of the network optimization technique depends on problem definition. In the first chapter, we have explained some of the algorithms often applied for similar purposes. In this case, the focus is(..)

WELDING WITH MICRO-JET COOLING AS A WAY TO IMPROVE THE MECHANICAL PROPERTIES OF MODE OF TRANSPORTATION SHAFT SURFACE

Damian HADRYŚ

The use of surface welding with micro-jet cooling allows to control the structure of the surface layer. It is a way to significantly increase the mechanical properties (for example hardness) of the surface layer. The effect of this is to extend the life of the kinematic pair. The main aim of this paper was to determine the influence of using micro-jet cooling for surface welding on tribological properties (e.g., friction coefficient and weight loss). Results of traditional surface welding (witho(..)

INFLUENCE OF SOCIAL CAMPAIGNS PROMOTING USE OF SAFETY BELTS AND CHILD RESTRAINT SYSTEMS: RESULTS OF SURVEY ON ROAD USERS BEHAVIOUR REGARDING RESTRAINTS

Katarzyna SICINSKA/ Maria DABROWSKA-LORANC

This article focuses on road traffic safety in Poland, where the risk of serious injury and death in accident has remained high. We present examples of campaigns on the use of seat belts and child restraints system between 2005 and 2015 promoting positive behaviour in road traffic. Results of self-reported data from survey in real traffic on vehicles’ road user’s behaviour due to the usage of protective equipment between 2014-2016 were collected and analysed. The scientific achievement of the ar(..)

IMPROVEMENT OF REGULARITY OF URBAN PUBLIC TRANSPORT LINES BY MEANS OF INTERVALS SYNCHRONIZATION

Jakub OZIOMEK/ Andrzej ROGOWSKI

This article describes a way of synchronization of communication lines in urban public transport. In the literature, no comprehensive methods have been presented to ensure the regularity of running public transport vehicles, except specific cases of this problem, which have little practical application. It demonstrates how this problem is difficult. In the article, the problem was presented more broadly – running of vehicles in different intervals, in lots of common fragments of routes, and runn(..)

APPLICATION OF ARTIFICIAL NEURAL NETWORKS FOR SHORTTERM PREDICTION OF CONTAINER TRAIN FLOWS IN DIRECTION OF CHINA – EUROPE VIA KAZAKHSTAN

Zhomart ABDIRASSILOV/ Aleksander SŁADKOWSKI

International container transport plays an important role in the exchange of goods between China and Europe, and accordingly, the efficiency of the transportation increases with the organization of special container lines (land and sea). Owing to its geographical location, the territory of Kazakhstan has become one of the main international landlines for passage of container cargo in recent years. Priority is given to solution of such problems as reduction of cargo delivery time, simplification (..)

Viktor DANCHUK/ Olena BAKULICH/ Vitaliy SVATKO

The paper suggests a method for determining the optimal location of service points (warehouses) based on the method for optimal planning of radiation therapy of malignant tumors. This method enabled us to identify the location of the most optimal number of warehouses taking into account their capacity for the required volume of freight transportation and distance from warehouses to consumers. The results of the study coincide with the results obtained by using the method of ant algorithm. The pr(..)
