Abstract

Paper deals with the problematic about the information quality impact and the basic methods which can optimize the costs of low quality of using information. First of all, it is important to purify the input data from the inconsistencies and measure the quality of data. This process assures to minimize the reasons that are responsible of poor quality of processes. Targets area of this paper is to identify and minimize the main reasons of delaying the passenger train by comparing years 2012 and 2013. Target groups of passenger trains were divided in three parts responsibilities of delaying – type of train, code of delay, group responsible for the train delay.

Abstract

An effective functioning of logistic chains through the use of intermodal transport inevitably necessitates elimination of potential constraints, which have a negative impact on the logistic chains implementation. The objective of the contribution is the analysis, definition as well as classification of constraints related to the logistic chains in the intermodal transport, which should enable to compare levels of constraints in different alternatives of the logistic chain implementation. Based on the comparison of the restriction levels, it is possible to select a more convenient way of the logistic chain implementation. The defined relevant constraints are assessed using scientific methods. These identified constraints have formed the basis for establishing a methodology, which enables to determine weights of constraints as well as to compare their levels on the basis of specific needs of entities.
