The aim of the paper is to present the concept of a digital twin (DT) as part of the Industry 4.0 strategy. In the form of a case study, a digital twin of a production line for the processing of engine blocks is presented, which will serve as a starting point for further research in the field of digitization of production processes. The research part describes the simulation model of the production line with the representation of the material flow as a basis for the creation of a digital twin. The simulation model was used to optimize the production processes of the engine block and to verify the increase in its productivity. A case study implemented through a digital twin enables testing and analysis of changes before they are introduced into real production.

Application of Soft-Skills Competence in Practice (Practice vs. Students

The paper deals with application of soft-skills competence in practice comparing of education and employers requirements. In addition to what a graduate is to know in terms of the knowledge theoretically acquired, the labour market today defines quite clearly the specific requirements in terms of what a graduate should be able to do, provide for, organize, including the demands related to their competences. The purpose of the paper is to assess the ethical credibility of selected subjects in the field of soft skills based on the analysis and conclusions of research conducted in 2018-2019 at the Technical University in Zvolen. The method of questionnaire survey was chosen for the execution of the research. The paper presents the results of the selected area research of soft-skills, which showed the most significant differences – stress resistance. To evaluate the results was used the Mann-Whitney test of significance which is an especially appropriate test for two independent and randomly selected sets of sample observations. At the end of paper are proposed recommendations for improving teaching in accordance with the requirements of practice.
