Abstract

The article concerns the analysis of the efficiency of the process of retooling the production line. The analyzes of preparation and implementation of production changes (serial production) are presented. The main issues of technical preparation were included in the analyzes. In addition, the investment indicators and the return of the funds involved were estimated. The work presents justification for undertaking a topic for the analyzed production system. Analyzes of the prosecutions were carried out earlier and a plan for implementing new procedures was created. The analysis of the improvement project takes into account investment opportunities as well as the time of engagement of the working group.

Abstract

The quality of the construction services provided has always played an important role not only in maintaining the safety and proper functioning of the construction objects in question, but also in other related features, which will also be the subject of a research study with the target group of the construction objects in question in the Mazowieckie Voivodeship in Poland.

This article explains the concept of quality and quality in terms of construction services. It indicates their essence and the process of implementation in the long-term perspective during the operation and exploitation of a building object. The process of quality assessment is based on the selection of contractors for construction works using fuzzy logic. The procedure of prequalification with the use of fuzzy sets was also used for such an assumed purpose.

Abstract

The small-sized enterprises, i.e. micro, small and medium enterprises (SMEs), constitute the basis of the Polish economy. They are considered as a key element among all economic entities, primarily driving economic growth by strengthening GDP, but also employment growth and social integration. Most of the Polish workers are employed in enterprises of “small size”. Therefore, effective management of work safety in micro, small and medium-sized enterprises is essential. It is very important to ensure appropriate and safe working conditions for employees of “small size” economic entities, but also for their long-term functioning on the market. Unfortunately, the results of publicly available reports indicate a relatively low level of occupational health and safety in “small size” enterprises. Occupational safety is considered primarily through the analysis of the basic triad of factors, which are - “technical safety at work” (T), “organizational safety at work” (O) and “human factor” (L). The paper presents the results of research conducted in “small-sized” enterprises (micro and small enterprises), including the analysis of technical, organizational and human factors. The tools that were used to implement the research assumptions include a questionnaire for the identification of threats in “small-sized” enterprises and the assessment of factors that affect work safety - with statistical analysis

Abstract

The paper-forming sieve is the most important part of the paper production machine. Reliability of the machine as a whole depends on the sieve’s quality. An analysis of the two constructions of the paper forming sieves, which were obtained by the plasma welding of the sieve’s wires, is presented in this paper. The mechanical characteristics of the two sieves, made of wires of diameters 0.15 mm and 0.20 mm, were tested, namely the tensile strength and elongation. The tests have shown that the sieve made of the wire of the smaller diameter has the better mechanical properties. This sieve is also better from the aspect of the water removal in the press section of the paper machine.

Abstract

Technological development is changing the skills model for employees in industry 4.0. Technical and IT competencies remain crucial for an engineer, however employers are increasingly appreciating soft skills, especially those that facilitate teamwork and communication or co-creation of innovations with customers and external stakeholders.

The article presents good practices for developing soft skills in engineers in industry 4.0 within the project “Curriculum Development of Master’s Degree Program in Industrial Engineering for Thailand Sustainable Smart Industry - MSIE4”.

Abstract

In times of innovation, rapid economic development and high competition, each producer tries to improve the condition of his company. Then the quality of services or products is improved, losses are minimized, production processes are optimized and costs associated with running a business are reduced. The Kaizen philosophy can be used to solve any problem and issue related to work in the organization. Its main value is to strive for the continuous company’s development through small ideas, which incrementally cause continuous improvement of the company. The paper presents how the functioning of the Kaizen philosophy in a company affects the initiatives of employees, which directly affect the optimization of processes. The presented research results show how innovative solutions consisting in limiting the use of masking tapes influence the improvement of product assembly process.

Abstract

Globalization and scarcity of resources have contributed to the need to meet and exceed customers’ higher expectations while reducing the number of employees, workload and consumption of available resources. This situation was initiated by the fourth industrial revolution, hereinafter referred to as “Industry 4.0”, which is based on the implementation of modern information technologies, associated with automation, artificial intelligence and a theory called the Internet of Things. All of this is aimed at improving efficiency, faster decision-making, which results in increasing the competitiveness of the company. Changes in the field of robotics, artificial intelligence and automation technologies indicate that with their increasing importance and implementation in organizations, there is a need to introduce new from teaching in the context of preparing engineers to work with new technologies based on cyberspace. The aim of the article is to review the literature on the importance of problematic teaching in the implementation of engineers for faster and more efficient implementation of Industry 4.0 in current production organizations.

Abstract

Modern industry confronts engineers completely new challenges. Technical skills in the light of the ongoing changes are no longer the only criterion for the effective work of engineers. On the other hand, engineers clearly show the need for development and taking new challenges. The need for a comprehensive acquisition of competences in both technical and psychosocial areas is increasingly expressed. Paper presents a model of employee competences essential for the future of enterprises operating in the Industry 4.0, which was created with using the Value Engineering methodology.

Abstract

The article presents methods of mapping data, information and knowledge value stream in order to identify the flow of key processes and to return knowledge exchange in the examined company. One large production company was audited. The amount of incoming to the company and processing information is so large that it must implement methods to improve their flow. Problems with knowledge exchange associated with high rotation contributed to analyzing the problem.

Abstract

One of the important factors on which road safety depends is adequate visibility. This article analyses horizontal visibility within road intersections. The visibility condition depends on many factors, primarily on the geometric parameters of road elements and the location of buildings, fences, vegetation etc., neighboring the road. The aim of the research presented in the study was to determine the current condition of horizontal visibility, on the example of twenty two intersections located mostly in built-up rural area along a provincial road near Czestochowa. The research was carried out by two methods (the analysis of satellite photographs and the visual method) and the obtained results were compared. The assessment of the security level was based on applicable regulations and technical guidelines. It was found that the results of the visibility assessment based only on the analysis of maps and satellite photographs are in many cases overestimated, due to the fact that many small elements not visible in the photographs are not taken into account and the occurrence of convex vertical road arches within the field of visibility. However, the main reason for the insufficient visibility at the many intersections is the fact that the geometrical parameters of roads and their surroundings were shaped in the past when the traffic conditions were completely different. It was also noted that road managers perceive this problem and take measures to increase safety within road intersections.
