    Approaches to support learning in today´s workplace

    Industry 4.0, Vol. 6 (2021), Issue 4, pg(s) 169-173

    Workplace learning supports acquiring knowledge and practical skills also to use up-to-date equipment by formal or informal methods and means and occurs mostly in the workplace. It contributes to learning of employees, employers and the organization as a whole.
    As a response to COVID-19 disease, workplace learning had to be changed. Companies need to consider Industry 4.0 to stay competitive in the market. Among the challenges regarding the transformation towards Industry 4.0 are requirements to re-skill the staff for the new work environment by using digital technologies. The staff has to adapt to the workplace transformation brought by digitalization, automation and robotic. So, learning at the workplace should be changed supporting cost-effective delivery modes, easy to access leaning resources, and flexible learning environments. This paper aims to present first some existing forms, benefits and requirements of workplace learning as well as factors that are impacting the workplace and can support to drive a new approach to workplace learning. Second, some learn ing methods
    like interdisciplinary experiential ones, reflection as well lifelong learning (LLL) supported by digital technologies are proposed which can be applied within workplace learning.
    Results about existing approaches in published papers, including the author ones, as well as of projects in this field have been used.
    Recherche has been done by the Study Group Lifelong Learning of the IAT, coordinated by the author. Finally, the methods described in this paper for workplace learning have been tested within an Erasmus+ project with participation of the author. The results should help managers, education responsible, employees to rethink their whole approach to workplace learning: the culture, tools, methods by adopting a new, modern understanding of what it means to learn at work by using digital technologies. The results should be tested also within other projects because due to changed situation during the Covid-19 and after it not all proposed approaches have been applied in optimal conditions. The factors driving workplace learning and the combination of described learning forms described in the paper have not been applied in this form until now.

    Industry 4.0, Vol. 6 (2021), Issue 3, pg(s) 106-109

    Industry 4.0 has brought about the interconnection of the physical, cyber and socio-economic worlds. Bringing these three worlds together creates a revolutionary approach that is a new trend not only in industry but also in other areas of the economy, thus pushing the economy and business forward. The concept of Industry 4.0 represents the interconnection of digitalisation and automatisation with the use of smart technologies. The main benefit of Industry 4.0 is to produce tailor-made products where lower costs and shorter production efforts are the main values that will attract new customers and thus the profitability of industrial manufacturers will be significan tly affected. Implementing Industry 4.0 in an enterprise will enable efficient use of human and natural resources and raw materials. It will also partially reduce the demands on the environment and create better living conditions for future generations. The intention of the paper was to explain how the Industry 4.0 concept is changing the direction of the Slovak chemical industry. The main objective of the paper was to explicate the Fourth Industrial Revolution in the form of the Industry 4.0 concept in 44 companies operating in the chemical industry in Slovakia on the basis of a knowledge base and a questionnaire survey

    Direct digital manufacturing – the role of cost accounting for online hubs to access industry 4.0

    Industry 4.0, Vol. 6 (2021), Issue 3, pg(s) 102-105

    Additive manufacturing is an established production method to realize Direct Digital Manufacturing in Industry 4.0. Especially for metal components, production requires high investment sums and high levels of know-how in the organisation. To make the advantages of the technology accessible even without high initial investment costs, co-called online hubs became an external and decentralised alternative to additive in-house production. After uploading the geometry to the online portals, material and post processing can be selected. The hub gives the customer a direct pricing response which is one of the main economic indicators for a purchase decision. The present paper focuses on the influence of the order quantity and the complexity of the components on the price algorithm. Therefore, sample parts of varying complexity and sizes are developed and uploaded to analyse data. Based on the in-depth findings of the study, the results are discussed.

    The intensity of technology development that we have witnessed in recent years has changed the expectations and attitudes of customers, as well as their understanding of value, and is becoming the new leading factor in the development of the industry. A retrospective of industrial production shows that all stages of change and development that it has gone through are stimulated precisely by the desire to meet the demand, expectations and needs of customers. In this sense, industrial enterprises around the world are clearly aware of the need for change. They should review their current production and sales strategies and focus their attention and efforts on building dynamic production models that will allow them to continue to operate successfully in a highly competitive market environment and changing customer requirements. Digitalization plays a key role in this new scenario in which industrial enterprises must fit in today. Digital technologies and the opportunities they create are the main driving force for the necessary radical change, which companies must rely on in order to increase their efficiency and, respectively, to maintain their competitiveness. This publication presents a conceptual model for assessing the digital maturity of the production system of the industrial enterprise.
