Fire alarm systems are an important part of the safety concept in complex buildings. For this reason, there are high availability requirements for the systems, which must be sustained by a maintenance concept. A shortage of skilled workers and rising costs in the construction and operation of buildings are pushing these concepts ever further. This study deals with proposed changes to the maintenance strategies to achieve cost and time savings in addition to an improvement in quality. As a first part of the work, the current state of research on developments in fire alarm systems and their maintenance and inspection concepts is analyzed within a literature review. The results serve as a basis for further research, which is based on a qualitative content analysis of expert interviews and standardized surveys to identify the weaknesses in current inspection strategies and future factors influencing the methods and technology of inspections through technical innovations. As a data basis for this study, expert interviews were conducted with experts from manufacturers, industry associations, and standards bodies in order to determine the possible influencing factors. To determine their relevance for the inspection, more than 40 experts were surveyed about testing the systems. The presented results show that new technical risks, such as cyber threats and networked plant structures, are insufficiently covered by current inspection strategies. Furthermore, inspection steps can be substituted by new technologies. The most important influencing factors that can be identified here are automatic self-test functions of components and remote inspection techniques of the systems. Finally, the results are discussed within the framework of a PESTEL analysis. In conclusion, it can be stated that the integration of identified impacts in future inspection strategies brings time and efficiency benefits in the operation of systems. [ABSTRACT FROM AUTHOR]

The paper reports research on the implementation of green aspects into the latest industrial revolution called Industry 4.0 and proposes the design of a business readiness level model for Industry 4.0. The analysis is based on the available maturity models for Industry 4.0, which are investigated to determine whether and to what extent they fulfil the 'green' trends by their name, content or specialized dimensions. This analysis was initiated over recent years, by a strong interest in integrating the elements and principles of Industry 4.0 into enterprises, together with an increased interest in achieving carbon neutral production and society in the coming decades, including recent EU Green Deal documents. The first part of the paper describes the basic requirements of the Industry 4.0, new digital strategies and green agreements. The major parts of the paper provide an analysis of current maturity and readiness models for Industry 4.0 together with specification, design and development of a readiness model for companies to implement Industry 4.0 with respect to green aspects. The final part of the paper provides an evaluation based on questionnaire survey with discussion, conclusions and avenues for future research. [ABSTRACT FROM AUTHOR]

This article introduces the possibility of using optimization methods Failure Mode and Effect Analysis (FMEA) and Design of Experiments (DOE) to improve experimental research processes. The FMEA methodology was implemented in the pre - experimental phase of the experiment. Potential risks has been established by FMEA methodology. Risks that should affected the overall result of the experiment have been determined in brainstorming process. These risks were tested during the experiment and data were evaluated by DOE and Student's t-test method. The results of this research confirmed that proposed methodology helped to verify the major risks which have significant impact to results of an experiment. [ABSTRACT FROM AUTHOR]

The contribution describes the scope and main subject designed within DIGI-Q project. The paper contains results from subprojects of information security management system (ISMS) implementation, managed by students of DIGI-Q course. Very interesting simple risk assessment method and risk management and their application within in small healthcare organization were developed. Criteria and procedures accepted are described.
