PT Journal AU Horak, J Suler, P Vrbka, J TI Analysis of Transportation Companies in the Czech Republic by the Kohonen Networks - Identification of Industry Leaders SO Communications - Scientific Letters of the University of Zilina PY 2021 BP A32 EP A43 VL 23 IS 1 DI 10.26552/com.C.2021.1.A32-A43 WP https://komunikacie.uniza.sk/artkey/csl-202101-0008.php DE Kohonen networks; artificial intelligence; industry leaders; transportation; cluster analysis SN 13354205 AB Computational models of artificial neural networks are currently used in different areas. Accuracy of results exceeds the performance of traditional statistical techniques. Artificial neural networks as the Kohonen map may be used e.g. to identify industry leaders, thus replacing the traditional cluster analysis and other methods. The aim of this contribution is to analyse the transportation industry in the Czech Republic by the Kohonen networks and identify industry leaders. The data file contains results - division of companies into a total of 100 clusters. Each cluster is subjected to analysis of absolute indicators and several parameters, average, as well as absolute, are examined. In total, 88 firms may be considered as industry leaders. Consequently, a fairly small group of companies has a strong influence on development of the whole transportation industry in the Czech Republic. ER
