So that the production process in manufacturing requires adjustments, one of which is by forming social manufacturing. This study aims to create an integrated production system model based on social manufacturing, which involves several Socialized Manufacturing Resources (SMR) as manufacturing resources that are socialized to produce a product. The methods used are field observation, literature study, design of a social manufacturing-based production system model, model simulation using ProModel software, and analysis of model simulation results. In this study, the simulation involves four SMRs, each of which makes a part that has been given specifications by the manufacturer based on customer requests. The product produced is the Sanitation Chamber, which is equipped with a control system to monitor reading data via the internet. The model simulation uses the Pro Model software and analyzes resource use, location utilization, and resource costs.","PeriodicalId":44097,"journal":{"name":"Management Systems in Production Engineering","volume":"30 1","pages":"230 - 237"},"PeriodicalIF":1.5,"publicationDate":"2022-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43254817","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}

Cognitive technologies are highly acclaimed and are being introduced into almost all aspects of life, especially in business. The article asks the question of whether the use of these technologies leads to a gradual humanization of machines while dehumanizing humans. The article is purely theoretical and based on a literature study of selected bibliographic items. On the basis of the analyzed texts an attempt was made to introduce the concept of artificial intelligence, cognitive technologies and algorithms. It also attempts to diagnose the state of work on the regulation of the legal situation related to the development of artificial intelligence and cognitive technologies, as well as the status of robots. The philosophical concept of dehumanization and its selected examples are also outlined. The discussion leads to the conclusion that the pace of development of cognitive technologies, overtaking the human ability to comprehend them, poses a threat of machines getting out of human control.","PeriodicalId":44097,"journal":{"name":"Management Systems in Production Engineering","volume":"30 1","pages":"269 - 275"},"PeriodicalIF":1.5,"publicationDate":"2022-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43067501","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}

With the development of the automotive industry, tires have become an integral part of society and the everyday life of the individual. As a result of the company’s development as a connection of transport, the demand for tires is increasing and the production of waste tires is also related to this. The use of end-of-life tires is almost endless and that is why tires are good to use in the circular economy. The circular economy is an economic system that aims to keep products and materials in use for longer, thus increasing their productivity and reducing waste. The paper presents a methodical concept of the plan for the extension of production capacities of rubber-based pressed products with the intention to produce noise reduction panels. The investment consists of the acquisition of the pressing machine and respective mould in the amount of € 180,000.

Residents noticed negative aspects of direct service, such as queues of people waiting for the case to be completed (26%), excessive bureaucracy (24%) or lack of parking spaces (18%). However, they counted on help in completing the necessary formalities by officials who should be: professional (20%), communicative (18%) and kind (17%). The use of the digital platform (ePUAP) dedicated to customer service was reported by 32% of respondents. At the same time, as much as 40% of the respondents, in order to save time and to simplify procedures, declared their will to use innovative methods of remote contact with public administration (e.g. via social media). The COVID-19 pandemic showed that it was possible to increase (even by 250%) the number of cases handled remotely, which with over 90% of households in Poland with access to a computer network creates opportunities for integrated development as part of the Smart City idea. The aim of the paper was to identify the residents’ expectations related to the provision of public services by local administration. Precise determination of the ways of perception of both direct and remote customer service has not only an application value. It also allows for further research study on the management of local government, including the organization of management control, as well as social communication of local governments.","PeriodicalId":44097,"journal":{"name":"Management Systems in Production Engineering","volume":"30 1","pages":"192 - 199"},"PeriodicalIF":1.5,"publicationDate":"2022-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43206571","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}

Trading CO2 emission rights has become a strategic area from the point of view of managing entities that emit CO2. The aim of the paper is to investigate and identify discrepancies in the presentation and valuation of CO2 emission allowances, CO2 emission provision liabilities in reporting, and to assess the impact of these discrepancies on compliance with the true and fair view principle on top of the informative value of the financial statements. An in-depth qualitative analysis was used to examine disclosures of CO2 emission rights in the 2020 consolidated financial statements coming from the largest energy sector groups listed in the WIG Energy Index of the Warsaw Stock Exchange in light of the relevant legal acts and literature. As a result of the research conducted, it was confirmed that groups of companies carry out a range of CO2 emission rights balance classification and valuation. There were also significant discrepancies in the disclosure of information about the creation and valuation of provisions for liabilities due to CO2 emissions. The discrepancies observed in the audited entities’ balance-sheet presentations and valuation of the acquired CO2 emission allowances and reserves resulting from IAS/IFRS in practice distorts the comparability of data presented in the financial statements. The research also revealed differences in scope of disclosed information, as well as its fragmentary nature. As a result, the comparison of data between groups in the energy sector in terms of their assets is impossible. Our study fills a research gap on the effects of using IFRS for the presentation and valuation of CO2 emission rights in the Polish energy sector and the impact of a differentiated approach to disclosures on the true and fair view conception in financial reporting.","PeriodicalId":44097,"journal":{"name":"Management Systems in Production Engineering","volume":"30 1","pages":"116 - 129"},"PeriodicalIF":1.5,"publicationDate":"2022-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46996306","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}
