- ItemThe importance of Industry 4.0 technologies when selecting an ERP system – An empirical study(Technická Univerzita v Liberci, ) Polívka, Martin; Dvořáková, Lilia; Ekonomická fakultaThe paper deals with the issue of the impact of the “Industry 4.0” concept on the process of selection of the enterprise resource planning (ERP) system. Firstly, review of the literature regarding the ERP system selection is presented, with the emphasis on the role of the new technologies in such selection. Secondly, the content of the term “Industry 4.0” is discussed, and put into context with the nature of ERP systems. The main part of the article then presents the results of the survey conducted among the medium and large industrial companies in the Czech Republic. Employees in the position of decision makers in the matter of selecting an ERP system were asked to participate. The survey used the form of questionnaire with close-ended questions with five-point scales, and investigated the attitude of the Czech manufacturing companies to the selected technologies of “Industry 4.0” and the importance of particular criteria for the selection of new ERP system. Investigated criteria were divided into 9 groups, where 5 of them were derived from previous research on the topic of ERP systems selections, and dealt with system price, portability, modularity, user experience and security. The remaining 4 groups were aimed at the selected technologies of “Industry 4.0” – big data, system integration, cloud computing and automatic identification and data capture. Kruskal-Wallis test and Neményi method of post-hoc analysis were used to compare the importance of particular criteria expressed by the respondents. The results show that although the companies are aware of the future challenges raised by the “Fourth Industrial Revolution,” in the selection of ERP systems they still emphasise mostly the previously used criteria such as price or modularity. As for the criteria connected to “Industry 4.0,” the ability of a system to deal with big data was assessed as the most important one.
- ItemPerformance of the socially responsible investment during the global crisis(Technická Univerzita v Liberci, 2013-08) Polívka, Martin; Pešík, Jiří; Ekonomická fakultaThere has been lately a big discussion about the causes of the current financial crisis. Many authors claim that financial markets and investments desperately need innovations. Socially responsible investment is one of such innovations, which has recently attracted great interest. The basic idea of socially responsible investment – investing only into the companies which fulfill some normative criteria – is actually nothing new, but is has been rapidly growing during the last decade. This paper is concentrated on the performance of such investments. According to the traditional portfolio theory, the SRI should perform worse or at best the same as the conventional indices. Nevertheless, there are also opinions proclaiming the superiority of the SRI. These opinions are based on the idea that the socially responsible behavior is a sign of the well-managed company, which is therefore supposed to keep its performance in the future more likely than the “irresponsible” enterprises. Many researches have been conducted to solve this controversy. First part of this paper therefore contains brief overview of the methodology and results of these studies. These researches are not up to date enough, though. Because of the huge change of economic situation caused by the global crisis, in our opinion it is necessary to make new analysis of the performance of the SRI under the current conditions. In this paper we analyzed the risk-adjusted return of the SRI stock market indices in comparison with the standard ones. Obtained results are consistent with most of the previous studies, i. e. no statistically significant difference between the SRI and conventional investments was found.
