The mining industry in Serbia has an important place in the country's economic development. Bearing in mind that the number of injuries that occur in the mining industry is unacceptably high, occupational safety and health is a challenge that existing and future mines will have to deal with. Studying injuries in mining, it was noticed that injuries requiring an absence from work for more than three...
Building a strong economy depends on numerous factors: technological, political, geographical but also and above all social ones. Currently, the ongoing fourth industrial revolution is primarily based on digitization of all processes in the conducted activities. The acquisition and processing of vast amount of data generates information which is very complex and not always unambiguous. Industry 4...
Ordoliberalism in contemporary legal orders is frequently associated with democracy or the so-called principle of a democratic state of law. However, in source assumptions of a doctrine of ordoliberalism one can perceive quite different preferred political systems. This paper aims at analysing the assumptions of a doctrine of ordoliberalism, as well as its place and role in a democratic system of...
The purpose of this article was to identify occupational hazards at the laser cutter operator's workplace and to assess occupational risk. The article also indicates the basic requirements for the analyzed workplace. Research methods included: observation of the workplace (using a checklist), interviews with the employer, selected employees and a health and safety specialist, as well as analysis of...
Physical activity is an inseparable sphere of human life, and is not rarely associated with work. Evolution has adapted man to perform various activities that meet their life needs. Man is created for walking, sitting, lying and standing. All these activities should take place in turns. Physical work should be varied in terms of dynamics and not limit people to stay in one position while performing...
Progressive, high-strength materials have an important position in the transport industry. In this industry, components are subject to high safety and reliability requirements because they often operate under long-term cyclic stress regimes. The paper presents results of fatigue resistance of high-strength materials such DOMEX 700MC, HARDOX 400, HARDOX 450, and INCONEL 718 (UTS from 850 to 1560 MPa)...
The article presents a case study of the practical use of BOST surveys to identify the most important factors in chosen enterprise. This article presents an analysis of the answers given to the question contained in the BOST questionnaire, refer-ring to the roof of Toyota’s house. Toyota’s management principles by Jeffrey Liker were pointed out, which refers to elements of Toyota’s house roof. Results...
The paper deals with problematic of machining lines of machine components for the automotive industry. There is a current issue of increasing labor productivity and economic efficiency of production with full safety of production and environ-mental protection. Therefore, for a specific practical assignment, the replacement of existing machinery using manual workpiece handling is performed by a fully...
The analysis of product quality is an indispensable action in developing enterprises. In case of mechanical products, the non-destructive tests (NDT) are effective way to make control. Non-destructive tests allow making assessing product quality with-out destroying it. Due to the dynamically growing requirements of customers and necessary, the improvement actions for demanding organizations important...
The paper presents several approaches to gauge repeatability and reproducibility (GRR) analysis regarding non-replicable measurements. Measurement systems have to deal with processes in which, by the nature of the measured object or by the type of measurement itself, measurements are not repeatable. In these cases, each sample unit can be measured only once. Such situations are referred as non-replicable...
The paper presents the importance of process security as one of the parts of Total Production Maintenance. Knowledge about the standards and factors used in monitoring production processes has been systematized. The good manufacturing practices in production continuity management are presented in the article.
The right use of creativity and innovation in business leads to increased competitiveness and development in your company. The progressive use of modern technologies and their presence in the economy causes problems in managing these assets and defining intangible property and their protection, which is directly related to the basic processes of making important decisions in the development of the...
The paper describes the method of producing a zinc coating on steel by electro-spark deposition technology. The technology of applying electro-spark zinc to the surface was presented. Microscopic observations and corrosion resistance tests were made. The possibilities of practical application of this type of coatings in the process of repairing zinc coatings, either damaged or with manufacturing defects,...
Currently, the industry is called as Industry 4.0, Internet of Things, Industrial Internet of Things, where devices, machines, information, organizations and people are connected to the network. Every day meet new solutions for Industry 4.o can be met, but in parallel with these solutions there are also threats in the field of security of industrial networks. Such threats have been called cyber-attacks...
Faced with ever-increasing customer demands and global competition, companies are forced to look for production reserves, increase efficiency and productivity. Hence, the need to monitor the use of the machine park has arisen, making it possible to identify waste and production reserves in the implemented technological processes. The aim of the article is to evaluate the effectiveness of the production...
In enterprises, accidents happen mainly due to improper and dangerous behavior of employees. The approach called Behavioral Safety (BBS) assumes that the most effective attempts to modify dangerous employee behavior are based on influencing people abuse. As a consequence, change in behavior leads to a change in the way of thinking and attitude. In the other words, as a result of using behavioral methods...
