Abstract. The paper presents problems of designing databases for various branches of industry. The development of information technologies and in particular of object-oriented programming has caused a change from data modelling to the modelling of applications. The increase of unstructured Big Data in Industry 4.0 era and requirements of sharing data model between many applications needs a reversion to data analysis and design and it is presented in the article.
The formation of precise products out of difficult to machine materials requires the usage of unconventional techniques and manufacturing technologies; and, above all, it requires adequate knowledge. The worldwide-accepted guidelines in this area are the national and international standards, and corporate experience known as expertise. The aim of this paper is to present the solution to the problem of collecting and sharing data on a variety of materials, within the extended application DBSMP (Database Special Materials Processing). While undertaking the works on the application to support the descriptions of the machining of special materials, it soon became apparent that the fundamental urgency, next to the machining process, is to provide function to the most detailed descriptions of the materials. A draft of the application was prepared with a number of assumptions for the database of standard descriptions and material descriptions, which is presented in this article with an example of high-speed steel.
The article presents the essence and significance of risk management processes in the project, as the key field for successful completion of the project, in the field of project management. Based on literature review, the methods and standards of risk management in the project as well as standards related to process safety were defined. The risk management process according to the PMBoK methodology was discussed as an example of an international project entitled 3DCentral – Catalyzing Smart Engineering and Rapid Prototyping.
The paper presents selected problems of design of machinery retrofit in Industry 4.0 era. In order to show the diversity of applications of new technological achievements, the case of radar revitalization as a museum exhibit has been shown. Ensuring functional safety and staff work safety has been changed into the safety of visitors to the museum and bystanders. Different approaches to the implementation of the safe stop function in both the internal adjustable frequency drive and the safety terrain zone are presented in the article.
The paper presents selected security problems in ICT systems and OT used in industry. In the Industry 4.0 era, the knowledge and competence of the IT staff and the maintenance staff must be linked. Selected problems and their analysis and solutions form the semi-secure network and use of NoSQL databases as a database bridges are presented in the article for various branches of industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
