The survey was extended to include an analysis of one of the companies subject to the survey. In the following, the case study regarding the production enterprise was also presented.

Abstract

The sales market requires both the highest quality of offered goods and satisfactory prices for the buyer. In addition to the reliability of the important aspects are also the time of order fulfillment, reliability, readiness to act around the clock, and service of sold goods after their sale. In the production and confection of conveyor belts, the priority is a customer who, having strictly defined product requirements, also has individually focused goals. To meet these aspects, you need to look after the product both during its production and after. The products of this industry are specific, so that they can be used, after sales service is often required to be installed at the customer and possible actions to maintain their good condition during operation. The article analyzes selected production processes of transmission belts to identify disturbances. The analysis uses the value stream mapping method. Then, improvement methods were proposed.

The application of the device for die temperature regulation ensures the safe operation.

Abstract

The aim of the article is to present the perspective of maintenance development in the context of the 4.0 industry concept. One of the factors that determine the safe and effective use of machines and devices is the properly maintained maintenance process. Correct performance of activities as part of this process requires the use of appropriate knowledge and experience from people implementing this process. Very important in this process is, above all, good organization of work and technical knowledge. The very rapid development of technology causes that teams dealing with the maintenance of traffic in enterprises must systematically acquire knowledge and optimize their activities. Effective exploitation of all types of devices is a set of rules, rules, procedures and actions, the main aspect of which is a human being. Knowledge resources should have appropriate substantive content adapted to the recipient. The article presents a modern solution supporting the maintenance process, taking into account the tools supporting the activities of human teams. The basic principles of maintenance in the enterprise covering machine monitoring systems, production management and management of information on the state of the machine park are discussed. There are also examples of the use of selected tools in the mining industry. Reference was also made to the prospects and directions of the development of maintenance in relation to the fourth industrial revolution.

Abstract

This paper aims to rank strategic objectives in a strategy map to improve the efficiency of strategy implementation. Objectives are ranked based on strategic destinations using the combination of Logarithmic Fuzzy Preference Programming (LFPP) and similarity method. In the first step, the weight of strategic destinations is obtained using LFPP technique; then objectives are ranked by similarity method. Similarity method uses the concept of alternative gradient and magnitude for effectively solving the general multi-criteria analysis problem. Finally, objectives are ranked in an actual strategy map. As a practical and efficient tool, the proposed approach can assist managers and decision-makers in drawing more efficient output from strategy maps.

Abstract

The Brown Coal Research Institute started the solving of the research project based on the optimisation of the shape and material of ground and mining machines in 2018. This research is necessary for increasing of efficiency of mining process in conditions of the Most Basin. The very important part of the research was the geological characteristic of the Most Basin main mining localities. Evaluation of the geological situation of the Bílina, Vršany and Libouš mines (mining of the overburden rocks in the ČSA mine finished) is the first stage of the solving of the project described in this article. The occurrence of sandy strata and the parameters of hard rocks are the most important parameters. The most important used laboratory analyses were the content of crystalline quartz, content of siderite, content of calcite and compressive strength. The location of the overburden cuts with similar mining conditions in different mining localities, very important for need of future research, is described in the end of this article.

Abstract

This article presents tools used in the Theory of Inventive Problem Solving (TRIZ) which are useful when assessing the evolution direction of technical systems. The following matters are discussed: the S-shaped curve, laws (trends and lines) of the evolution of technical systems, multi-screen diagrams, as well as analysis of evolutionary potential. Inventive laws formulated by Gienrich Altshuller as well as laws previously formulated by a Polish writer and promoter of knowledge, Aleksander Głowacki, writing under the pen name Bolesław Prus, have been presented. Finally the innovation roadmaps have been shown. The use of individual tools has been supported by practical examples taken from research performed by the authors, and the usefulness of individual methods was evaluated. All methods have been compared and evaluated.

Abstract

The purpose of the paper is to determine the degree of Polish companies’ maturity applying for Quality of the Year certification based on the EFQM excellence model. The study was conducted using a questionnaire (CAWI – computer assisted web interview). Company to get certified Quality of the Year had to get in the field of self-assessment carried out by the EFQM model at least 56%. Results and its analysis showed that among the 49 analyzed large companies seeking Quality of the Year certification only 3 achieved a value of 80% and above. Among the 10 companies selected for analysis only 3 has taken improvement actions. Based on the study carried out, the authors demonstrated that the analyzed companies that have been certified Quality of the Year are mature and conscious of quality, continuously improve, and apply modern techniques (traditional quality management tools, new quality management tools, quality management methods). The factors that determine the maturity and the awareness of the company in terms of quality are the elements included in the EFQM model (1. Leadership. 2. Vision, strategy, policy. 3. Human resources management. 4. Resource Management. 5. Process Management. 6. Customer satisfaction. 7. Employee satisfaction. 8. Cooperation with the environment. 9. Achievements companies in relation to the goals), as well as the awareness and the ability to use modern techniques.

Abstract

This study addresses the issues of water management safety management in the context of shaping the appropriate level of municipal services in Poland, related to quality standards and the availability of water resources for enterprises and the local community. The literature review presents examples of activities concerning the evaluation of the quality and availability of groundwater and their suitability for domestic and commercial use in the world. The key parameters of water intended for human consumption, which affect its quality, have been selected based on the literature and the Polish standards set out in the regulation. On this basis, appropriate parameters for case-study research were selected. In the following, the analytical methods and tools used to assess water quality were characterized. In the case study example, the analysis of water parameters from selected three different intakes in 2015-2017 (Tęczowa, Stodoły and GPW Rybnik-Północ) was performed and the functioning and role of the internal Water and Sewage Laboratory in the safety management of water economy in the water and sewerage company has been presented.

Abstract

The article presents the problems related to the application of alternative fuel like solid biomass in the shipbuilding. The decreasing resources of the crude oil, the requirements regarding environmental protection as well as the increase of the liquid fuel prices were the reason for the study. The solid biomass comparing to the liquid or gaseous forms has relatively low calorific value. In order to increase this value the solid biomass is subject to the densification or torrefaction process and most often occurs in the shape of pellets. In this form it could be useful on ships. A test stand has been characterised where it can be experimentally verified whether ship’s rolling does affect the changes in flow resistance values during the pneumatic transportation of solid fuel from the storage facility to the boiler. On the basis of the measurements the hydraulic characteristics have been provided for the piping located on the movable platform with and without granular material. The changes in the platform oscillation period have influence on the change in the pressure inside transport piping for each investigated material. The results also show that the platform constantly inclinations do exert an influence on the pressure drop in the transport pipeline during transporting the granular material. It is smaller when the position is inclined. Comparing the results obtained for the different transported materials of a similar nature of the pressure fluctuations could be observed.
