Even though the rules for the free circulation of machinery within the European Union (EU) market have existed for more than 30 years, accidents related to their activities have constantly been reaching significant value. When designing a machine, the design must stem from a risk assessment, where all stages of its life cycle and the ways to use it must be taken into consideration. In industrial operations with old machinery, despite fulfilling its function reliably, the safety level is below the developing requirements for safe operations. The proposed methodology to assess machinery safety conditions comes from the assumption of the proper application of risk assessment steps and their effectiveness in risk reduction mainly through implementing both effective and efficient preventive measures. The objective of the research applied in three operations was to verify the methods concerning machinery safety and its management. The created methodology, based on 19 requirements for safety, evaluates the level of current measures using a criterion of the current safety status and the total effectiveness of safety measures. Its output is the assessment of the efficiency level of the implemented safety measures of each machine as well as of the whole operation.

Even though the rules for free movement of machinery within the European Union market have existed for more than 30 years, accidents related to their activities have constantly been achieving significant value. When designing the machine, a designer must stem from risk assessment, whereas all stages of its life cycle and ways of its use must be taken into consideration. In industrial operations, there is old machinery, which, although fulfilling its function reliably, the safety level is not in accordance with the developing requirements for their safe operation. The proposed methodology of assessment of the machinery safety condition comes out from the presupposition of the right application of steps of risk assessment and their reduction mainly by means of implementation of both effective and efficient preventive measures. The aim of the research applied in 3 operations, was to verify the method of machinery safety management. The created methodology based on 19 requirements for safety evaluates the level of the actual measures by means of the so-called criterion of current status and total efficiency of measures. Its output is the assessment of the efficiency level of implemented safety of each machine as well as of the whole operation.

At present, the management of organizations is dominated by efforts to integrate management systems, based on risk management. The introduction of digitization and the application of appropriate methodological tools make it possible to optimize key processes and information flows, increase data reliability and thus support management decision-making. This article describes the development and current trends in the management of organizations, analyses the principles of management, and approaches to maintenance management (MM), with respect to the requirements of Industry 4.0 (MM4.0). Based on this analysis, and through two research questions asked, it qualitative evaluates the effects of the nine basic pillars of Industry 4.0 on the implementation of a comprehensive approach in management systems, draws attention to the gaps of misunderstanding or non-use of appropriate tools in process management as well as in maintenance management. Finally, it presents a consideration of the development of new comprehensive management concepts integrated into a comprehensive management system in the Industry 4.0 environment, and through positive responses to RQs it creates space for further research in the field of MSI4.0 and MM4.0.
