Abstract. The Event Tree Analysis (ETA) is a tool for assessing system and process safety. It facilitates detecting potential risks, as well as relations existing between actions or events. This method explores the path from the initiating event to the outcome (most often representing the immobilization of the tested object), with particular emphasis on intermediate stages affecting the technical condition of the object. Unlike the FTA analyses, which have a deductive nature, the ETA analysis is inductive. The aim of the work was to estimate the probability of occurrence of unwanted events concerning the operation of a car turbocharger. Based on the performed studies, the impact of the standard safety systems on the operation of the component was checked. Afterwards, more effective safety solutions were proposed. Initiating event was distinguished in the system. The occurrence of such an event could result in a complete immobilization of the component. To accomplish the task, it was necessary to use safety barriers aimed at reducing negative effects of initiating events. The calculation of probabilities of occurrences of various effects in each of the cases helped quantify the selected damages to the turbocharger.

One of the greatest challenges of our time is global climate change. A key strategy for mitigating the emission of greenhouse gases is the improvement of energy efficiency. Manufacturing industry stands for a large share of global energy end-use but has yet to achieve its full energy efficiency potential. A barrier to untapping this potential is the lack of detailed data on industrial energy end-use at the process level, preventing the development of sound, bottom-up energy key performance indicators (KPIs). This hampers the ability to create a profound strategy for improving industrial energy efficiency because it is not known in which end-use processes the largest energy efficiency potential is to be found. Increasing knowledge about energy end-use at the process level also increases the possibility for energy comparisons, i.e. benchmarking, at the process level. This thesis aimed to investigate how to further enable industrial energy benchmarking at the process level, primarily for the pulp and paper and wood industries. Relevant benchmarking requires that data on energy end-use is collected using a common, harmonized categorization of processes and that joint energy KPIs are applied. Therefore, suggestions for standardized categorizations of end-use processes were investigated for the studied industries. Based on the calculations, and under the assumptions made in this thesis for estimating the energy efficiency potential of end-use processes, diversity was found between industries around which type of processes have the largest efficiency potential. It also emerged that, due to the lack of detailed data about energy end-use and lack of information about energy efficiency measures, processes accounting for a significant share of the energy efficiency potential in the wood industry risk being overlooked. It is not certain that current energy policies are sufficient to reach the full potential identified. The lack of information about energy end-use and energy efficiency measures implies that neither industrial actors nor policy-makers are able to develop thorough energy strategies or roadmaps for improved energy efficiency. While the outcomes of this thesis show that a large share of Swedish pulp and paper mills carry out energy benchmarking to some degree, energy managers emphasized that benchmarking in this particular industry is difficult because it requires a deep understanding of the industry's heterogenous and integrated processes. This thesis proposes a widened perspective on energy benchmarking and its role in industrial energy management; namely, also considering the process of how energy KPIs are implemented within in-house energy management. A process that enhances energy management includes the continuous monitoring, visualization, and revision of KPIs. In this thesis, a method is developed that encourages the bottom-up implementation of energy KPIs in the pulp and paper industry, which further enables industrial energy benchmarking.

Abstract-This paper aims to present a process of implementing a Single-Minute Exchange of Die (SMED) method and a manner of evaluating the effectiveness of such an undertaking. The subject of the study is a printing enterprise that conducts its business activity in Poland and the chosen research area is a flexographic machine Gidue Master Combat 430. The article presents specific stages of implementing the SMED method, describes activities aimed at determining the causes of the resulting waste and proposes ways of improving the changeover process. It should be emphasised that the article presents the effectiveness of implementing the SMED method in a measurable and quantitative manner.
