    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.

    Industry 4.0, Vol. 6 (2021), Issue 2, pg(s) 63-65

    Croatian entrepreneurs recognize the importance of Industry 4.0. for the overall development of the economy. There is an awareness that product digitization can ensure employment growth and modernization of the economy leading to higher financial results. Some Croatian solutions in terms of digital products are already present. Nevertheless, Industry 4.0 in Croatia is still in its infancy, which is an opportunity for Croatian companies, but they are facing strong competition on a global level. There are no consistent data on the level reached by Croatia in terms of smart production, but there is data that Croatia is somewhere in the European Union average in terms of technological renewal of its companies, but in terms of the share of new products it is at the bottom of the European Union. What Croatia is like in terms of total industrial production, employment and productivity in industry, and what is the strategy for achieving greater competitiveness is the topic of this paper.

  • THEORETICAL PROBLEMS IN INNOVATIONS

    Conceptual model for assessing the digital maturity of the production system

    Innovations, Vol. 9 (2021), Issue 1, pg(s) 11-14

    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.

    Modeling of аgent-based cyber-physical systems using goal-oriented approach

    Mathematical Modeling, Vol. 4 (2020), Issue 4, pg(s) 106-109

    Cyber-physical systems (CPS) integrate computing, networking and physical dynamics and are characterized by a high degree of heterogeneity and parallelism, with high dimensionality and complexity, including a variety of decision-making capabilities and control logic. Modeling and simulation of cyber-physical systems are considered important stages in the design, development and operation of CPS and their components. The main aim of the paper is to describe and analyze the evolution of agent based approach in the field of CPS and to define the basic requirements to the agent based systems regarding CPS. Based on O-MaSE methodology a software process model for agent based development of CPS is proposed. The approach includes the creation of 10 models reflecting various aspects and functionality of the CPS. The suggested approach is analyzed in terms of meeting the basic requirements for agent-based systems, imposed by the peculiarities of cyber-physical systems and fundamental requirements for their introducing, such as flexibility/changeability, reliability, reconfigurability, adaptability/agility and dependability.
