    • PREDICTIVE ANALYTICS FOR INDUSTRY 4.0

      pg(s) 273-276

      The Industrial Predictive Analytics for Industry 4.0 is a system that predict and prevent machine failures and breakdown by analyzing time-series data (temperature, pressure, vibration etc.) received from sensors embedded in machines and equipment. The system can analyze machine parameters to identify patterns and predict breakdowns before they happen. The core of the proposed system is based on Artificial Neural Network approach (both Deep and Shallow Neural Networks). Artificial Intelligence and Artificial Neural Networks allow analyses the huge amounts of data collected from the manufacturing process and predict what will go wrong, and when. The proposed system works in the paradigm of Industry 4.0 and provides the abilities in the area of predictive maintenance. The Industrial Predictive Analytics for Industry 4.0 also contains a decision-making system and support system that significantly increases the level of maintenance.

    • VEHICLE CLASSIFICATION BASED ON THEIR GPS SIGNAL SHADOWS

      pg(s) 286-289

      The goal of this paper is to study algorithm for detection and classification of moving objects based on parameter estimates from their GPS signal shadow. The suggested algorithm uses satellite GPS signals to create radio barriers and to detect moving terrestrial targets. It can be examined as an algorithm for secondary application of the wireless technologies (SAWT). This technology is extremely modern and up-to-date and can find application in Industry 4.0 with regard to the reduction of the electromagnetic radiations. The GPS signals included shadow from several moving vehicles, processed in MATLAB environment in order to obtain the estimations of their parameters. In IBM SPSS Statistics, Scheffe test is used for classifying the moving objects. The results reveal that proposed signal processing of the GPS signal shadow combined with this statistical approach can be successfully applied in practice for object classification.

    • NEW APPROACHES FOR OBTAINING SELENIUM (Se) FROM NATURAL RESOURCES

      pg(s) 302-305

      In the last few years, application of selenium has increased significantly due to its unique possibilities to acts as an antioxidant and as an anticancer reagent in human body. Due to this, selenium is one of the most important chemical elements for human health. Recently, selenium usage in microelectronics was significantly increased as semiconductors with characteristic electronic properties. The selenium is the least abundant element in earth crust, but as the application fields of selenium are widely opened, the needs of this element are larger. This opens new views in the field of improving existing and developing new technologies for extraction of selenium.
      In this work, a new technology for extraction of selenium from natural resources was developed, by combining the advantages and removing the disadvantages and weaknesses of the existing technologies. The sediments near mineral water springs and used water filters with content from 0.0656 to 0.9291 % wt. of Se were used as mineral selenium resources. Also, the plants such as Astralagus bisulcatus and Stanleya pinnata with content of Se around 100 mg·kg–1 biomass were used as a plant resources. The technology presented in this work is a combination of pyrometallurgical and chemical methods in order to obtain intermediates reach with selenium, and further chemical and electrochemical extraction of selenium from these intermediates was done. The analyzes were performed using Inductively Coupled Plasma – Atomic Emission Spectrometry (ICP-AES). The results have shown that from mineral resources can be extracted pure red technical selenium with analytical grade up to 48.3 % of Se. From the plant resources can be obtained enriched selenium intermediates with analytical grade from 1.367 to 1.604 % wt. of Se which are potential material for medicine applications.

      pg(s) 306-308

      Tools, which are used while carrying out of the individual managerial functions are constantly evolving and responding to the changes of outer environment. In current conditions the most significant factor, which effects business environment, is Industry 4.0. It is a phenomenon associated mainly with automatization, digitalization and the Internet of Things. The main aim is to identify changes in the application of methods and techniques in carrying out of the individual managerial functions in the context of the impact of the Fourth industrial revolution on the theoretical level, based on a research of available scientific literature. The results of the theoretical research point to the fact that the topic of industry 4.0 is new in the context of management, and the research does not have any influence on the individual managerial functions, which are planning, organizing, controlling, human resources management and leadership. Most of the scientific work focuses on the field planning, organizing and controlling. On the other hand, not mentioned are the functions like human resources management and leadership, within the effects of the Fourth Industrial Revolution on the tools and methods, which are used for the implementation.

    • ERP SYSTEMS IN CROATIAN ENTERPRISES AND INDUSTRY 4.0

      pg(s) 313-316

      Resource planning in manufacturing companies is crucial in the context of Industry 4.0. Enterprise Resource Planning (ERP) systems that enable vertical and horizontal integration between different operational and management levels are essential for monitoring process execution through real-time data access and for making decisions according to these data.
      The implementation of the ERP system is one of the key indicators highlighted by the European Commission (more than 100 indicators) in the Digital Agenda for Europe (A Europe 2020 Initiative), which sets the goals for the growth of the European Union by 2020. It is important to make an analysis of the state of implementation of the ERP systems in the Republic of Croatia. We researched within the metalworking industry in Croatia. Purpose of the research conducted is to determine the state of implementation of ERP systems in metalworking companies and on the compliance of ERP systems with Industry 4.0 and to investigate the opinions of ERP system users on the extent to which the ERP system they use meets the requirements of Industry 4.0.
      The main objective of our paper is twofold: to present the features of modern ERP systems in the Industry 4.0 framework and to present the results of our research.
