    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.

    This paper discusses a case of implementing Industry 4.0 solutions with existing legacy informational system in cement-producing factory. One of the main reasons the company wants to keep its existing ERP solution is because is too complex and cannot be ported to a contemporary computer architecture. The plant also needs to automate and modernize the process of loading their products, but the company management does not want to invest in modern computer servers and a new ERP system. That’s why they decided to implement a hybrid solution – a modern Industry 4.0 IoT devices with .NET client application using the existing legacy DEC Alpha as a server. Here, the required technologies used for developing that software solution are overviewed and all parts of the software solution are described. Finally, the benefits and effectiveness of such a hybrid software solution are shown.

    Industry 4.0, Vol. 5 (2020), Issue 2, pg(s) 90-93

    One of the most expected and the most desired implementation of modern technologies is the concept of a Smart City. Meanwhile there are many buzz-words known to describe the ability of implementation of many approaches to provide control for Smart City. Many of such technologies had become known for Industry 4.0 concept, including 5G mobile Internet and autonomous aerial vehicles (so called drones). Nevertheless, there is an open question of how to provide and support limits where and when UAV (unmanned aerial vehicle) should be able or not to fly over the city. Naturally, the self-driven drones equipped with a batch of sensors and able to avoid some  obstacles would not be enough for everyday use within Smart City. Current paper is focused on discussion of possible solution to provide UAV with up-to-date data on restrictions, that may be required in a modern city.
