Abstract

Bankruptcy models are used to assess credit risk and predict financial situation to indicate the probable bankruptcy of the company. Contribution deals with the application of chosen bankruptcy models in analysing and predicting the financial health of selected companies. Most of the models have been developed abroad. In case of Slovak Republic, its application and correctness of the results can be problematic; therefore, we have focused primarily on those that have emerged in countries with a similar economy. We have calculated the selected prediction models in a sample of 500 Slovak enterprises. Predictive ability lower than 64% is considered as unfavourable. As part of the contribution, based on expert literature and relevant legislation, we have defined the criteria that allow to divide businesses into two groups: prosperous and non-prosperous. In the end, we compared the results of the selected models with the inclusion of enterprises in a prosperous and non- prosperous group based on the criteria set by us. We also dealt with examining of error types I (when an enterprise in bad financial condition is included in a non-bankruptcy group) and II (when an enterprise in good financial condition is included in a bankruptcy group). The aim is to analyse the predictive ability of the selected bankruptcy models.

Abstract

The main purpose of the paper was the structural analysis of the connections network used by a railway carrier Koleje Dolnośląskie S.A. operating in southern Poland. The analysis used simulation methods. The analysis and simulation were based on graph theory, which is successfully used in analysing a wide variety of networks (social, biological, computer, virtual and transportation networks). The paper presents indicators which allow judging the analysed connections network according to an appropriate level of transport services. Simulation results allowed proposing some modifications for the improvement of the analysed connections network. The paper also demonstrates that graph theory and network simulations should be used as tools by transportation companies during the stage of planning a connections network.
