Abstract The paper is devoted to the construction and design solutions of the power supply and drive systems of a prototype, lightweight LHD (Load-Haul-Dump) loader with an innovative “in-wheel drive” transmission system. The loader is a Battery Electric Vehicle (BEV) with replaceable energy storage. It is intended for use in underground mines with no explosion hazard, especially in metal ore mines. The developed model contains four independent, electric drive systems installed in the road wheels. The paper presents the results of simulation tests, which enabled estimating the required driving power and electricity demand in various regimes and working conditions of the loader. The results of the calculations were used to determine the parameters of the drive system components and the battery capacity. Challenges and problems faced by constructors of BEV LHD loaders with an in-wheel drive have been pointed out.

Abstract The smart city concept, influenced by societal changes, technology, and geopolitics, is transitioning towards a human-centered model—Smart City 3.0. Emphasizing community engagement, this model ensures that new technologies are tailored to each city’s unique needs. The creation of a participatory society is essential for this approach, fostering public involvement in decision-making. Core mechanisms include public consultations and participatory budgeting, as legislated, enhancing co-management between authorities and residents. To successfully implement Smart City 3.0, it is vital to build a partnership based on mutual trust between local authorities and communities. Opinions must not only be expressed, but factored into city planning and development. Advisory bodies like city youth councils illustrate this approach, engaging youth in meaningful roles and ensuring their interests are represented. This paper investigates the vital role of community members in the creating of smart city. Additionally, the paper conducts a comprehensive review of various models of participation, evaluating their respective strengths and weaknesses within the context of smart city development.

Abstract Zinc and lead metal ores are minerals intended for strategically producing raw materials for the Polish economy, as indicated in the key Polish document: State Raw Materials Policy (PSP2050). It was specified among others that an important factor that will influence the development of Polish economy will be the access to key mineral raw materials from domestic resources. Currently Polish Zn-Pb ores mining no longer exists as the last operating mine Olkusz-Pomorzany that belonged to the Mining and Metallurgic Plant “Bolesław” Joint Stock Company due to the depletion of resources finished extraction in 2020. Despite this fact there still are areas of great potential in the scope of these minerals in Poland. It is the Zawiercie region, where there has been no extraction of these ores so far and is believed to have the best perspectives for future development. One should connect with this region the nearest future of functioning of the domestic Zn-Pb ores’ mining. It is in this region that the “Zawiercie 3” ore is situated. The ore was documented in 2014 by a private investor within the framework of the permit to search for and identify Zn-Pb ore deposits and it is currently the largest as to resources Zn-Pb ores’ deposit in Poland. Its resources are currently over 35 million tonnes, which constitutes app. 39% of all the documented balance sheet resources of Zn-Pb ores in Poland. The presented geological works performed by the private investor on the area of the “Zawiercie 3” ore and the results that were achieved thanks to them clearly indicate that well-designed and thoroughly performed exploratory and evaluative works that combine international standards and Polish guidelines can significantly influence the degree of documentation and the increase of resources in undeveloped Zn-Pb ores’ deposits.

Abstract The aim of the article is to analyze the impact of effective time management on the performance of workstations in the context of the conflict between maximizing workstation utilization and minimizing the number of items waiting in the queue. The article utilized the FlexSim program to build a simulation model of the workstation and conducted optimization using the built-in optimizer. The research demonstrated that effective time management has a positive impact on workstation performance by reducing the number of items waiting in the queue, leading to increased throughput and reduced delays in production processes. An important aspect of the analysis was the application of a multi-criteria optimization approach, which allowed for achieving a balance between maximizing workstation utilization and minimizing the number of items waiting. Multi-criteria optimization considers diverse goals and decision criteria, leading to a more comprehensive approach to optimizing production processes. As a result, effective time management on workstations, based on analysis and multi-criteria optimization, can significantly improve the efficiency and performance of production processes. This analysis can be a valuable tool for organizations seeking to optimize their processes and achieve a competitive advantage in the market. The analysis conducted in the article confirms that effective time management has a beneficial impact on workstation performance. The use of a multi-criteria approach in optimization enables achieving a balance between various decision factors. The presented simulation model and research results can be useful for decision-makers in the manufacturing field who aim to make more informed decisions regarding planning and optimizing production processes to enhance efficiency, effectiveness, and customer satisfaction.

Abstract The Banbury mixing process (BMP) is to supplies the specific characteristic compounds for the tire manufacturing process. Idle time in the BMP was a problem caused by the aging process between mixing steps and the limited space for processing, measured in pallets. In this study, the resource-constrained project scheduling model (RCPS) is modified in case of the objective function and the input value of resource constraint to minimize idle time (SST). The complete minimization (Cmax) is changed from minimizing the starting time of the last job to the starting time of all jobs. In addition, the non-limited resource is defined as the input for the space capacity to reduce the idle time. As the results, the SST can provide the schedule that make less 5 time periods of idle time. Moreover, when considering the relationship between mixing and aging, aging process that is scheduled from SST starts immediately comparison to Cmax that some of aging process are not. Furthermore, the effect of the quantity of pallets was also examined. Although the non-limited resource does not make any delay to the schedule but the limited quantity is not. When pallets are limited, aging jobs were significantly impacted, with the last aging pallet being delayed. To reduce delays, it prepares an adequate supply of pallets that is close to or equal to its requirement that is defined by the non-limited resource. Further research combining the scheduling of the BMP with the tire manufacturing process and more techniques to modify RCPS are applied.

Abstract The objective of this paper is to propose effective methods to implement sustainable development principles among young people, both in schools and universities. The authors of this article recognize the significant potential among young individuals whose actions and choices have a substantial impact on the environment. By analyzing the knowledge and behaviors of young people towards sustainable development and environmental protection, based on surveys conducted among pupils and students from the south-eastern region of Poland, this paper identifies gaps that require improvement and proposes actions aimed at raising pro-ecological awareness among the youth. The analysis revealed that only 25% of the respondents have heard about the “Agenda for Sustainable Development – 2030”, 20% were familiar with the goals of sustainable development, and few have participated in initiatives for sustainable development. However, 58% of respondents claimed to engage in activities for environmental protection in their daily lives. The article also presents the degree of compliance with the assumptions of the 2030 Agenda for Sustainable Development on both global and local scales. Furthermore, the paper analyzes two aspects of students’ awareness of sustainable development: their knowledge of goals and documents, and their pro-ecological behavior in daily life. Based on the findings, this paper proposes ways to introduce sustainable development principles in selected areas of school and university functioning to enhance ecological awareness and shape pro-ecological attitudes among young people. Concrete actions to facilitate implementation are also suggested.

Abstract The foundation of the social communication system of the Polish police is the press officers of district and city departments, who maintain regular contact with journalists of local and regional media, and incidentally also with national or international mass media. The aim of the 2022 survey was to determine the media relations activities, techniques and tools used by officers. All press officers in the police garrison in the Silesian Voivodeship participated in the research project. 100% of press officers took part in the survey. Responding to the expectations of journalists police officers prefer direct contact with journalists, including 52% by phone. Although press officers consider social media to be a good method of contacting the public (30%), they do not use it themselves in contacts with journalists. They prefer to use the official police website (28%). Police spokesmen, due to the information they have, gain the attention of the mass media and do not have to use modern communication techniques to attract journalists. Maintaining constant contact with journalists, press officers also assessed the level of their professionalism. According to the respondents, TV journalists are characterized by the highest professionalism (41%). In second place are press and radio journalists with a similar number of indications (27% and 24%). The professionalism of Internet editorial staff was rated the worst (8%).

Abstract One of the basic stages of mining operations is development work. During them there can occur the events that affect the process of development work as well as the safety of workers. This article conducts a process risk assessment using the Failure Modes and Effects Analysis (FMEA) method to identify events that disrupt the development work process, along with the causes of the occurrence of these events. The study covered the process of development work i.e. the execution of the M-2 roadway in seam 502/1 realized at a depth of about 550 m with an assumed length of about 500 m. As a result of the study, those risks for which countermeasures should be applied were identified, and measures were proposed to minimize the risks involved. As part of the research, an FMEA evaluation form was created to assess process risks in the execution of similar work. The highest process risk was identified for the drivage of the excavation with a road header, and is related to the possibility of frequent failure of hydraulic systems. Similar process risk results were obtained for the risk associated with improper execution of mining with explosives and the need to perform additional blasting work in the excavated roadway. The results can contribute to reducing the time of coal face stoppage during development work, and thus improve the process of them and reduce the costs incurred during this process.

As part of the research, an FMEA evaluation form was created to assess process risks in the execution of similar work. The highest process risk was identified for the drivage of the excavation with a road header, and is related to the possibility of frequent failure of hydraulic systems. Similar process risk results were obtained for the risk associated with improper execution of mining with explosives and the need to perform additional blasting work in the excavated roadway. The results can contribute to reducing the time of coal face stoppage during development work, and thus improve the process of them and reduce the costs incurred during this process.","PeriodicalId":44097,"journal":{"name":"Management Systems in Production Engineering","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48911175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
