Currently, a dynamic growth of interest in residential buildings located on the water can be observed in Poland. However, the lack of legal regulations, the increase in society's affluence and overpopulation in city centers lead to reflection on the development strategy that should be implemented for maritime construction. The publication presents a proposal of four development strategy concepts: aggressive, conservative, competitive and defensive, developed for floating homes (FHs) based on the authors' own research. The strategy concept that, in the authors' opinion, should be implemented was indicated using the TOWS-SWOT analysis. A detailed analysis revealed that the strategy that obtained the highest result in the study was the aggressive strategy.

W celu poprawy jakości powietrza w miastach oraz zmniejszania emisji CO2 przedsiębiorstwa zachęcane są do budowy układów kogeneracyjnych, czyli skojarzone wytwarzanie ciepła i energii elektrycznej. Budowa układów kogeneracyjnych jest zgodna z ideą zrównoważonego rozwoju, ponieważ skojarzona produkcja energii i ciepła cechuje się bardzo wysoką sprawnością procesu dochodzącą do 90%. Do produkcji tych samych ilości ciepła i energii elektrycznej zużywa się mniej paliwa niż w przypadku produkcji rozdzielonej. Wytwarzanie energii w skojarzeniu pozwala na bardziej efektywne wykorzystanie paliw i zmniejszenie globalnej emisji CO2. Polska, która jest największym producentem węgla w Unii Europejskiej dzięki wykorzystaniu układów kogeneracyjnych wykorzystujących gaz pochodzący ze złóż węgla kamiennego, może dzięki nim zmniejszyć emisję metanu do atmosfery, co ma szczególne znaczenie w przypadku wprowadzenia opłat emisyjnych od metanu. Opracowanie przedstawia wyniki analizy ukierunkowanej na identyfikację ryzyka występującego przy projektach budowy układów kogeneracyjnych małej mocy dla różnego rodzaju przedsiębiorstw. Autor rozdziela istniejące ryzyko ze względu na miejsce pochodzenia ryzyka (źródła zagrożeń) oraz przedstawia przesłanki do zainstalowania takiego układu. Na końcu autor przedstawia analizę SWOT oraz PEST budowy układów kogeneracyjnych małej mocy.

EN

In order to improve air quality in cities and reduce CO2 emissions, companies are encouraged to build cogeneration systems, i.e. the combined production of heat and power. The construction of cogeneration systems is in line with the idea of sustainable development, since the combined production of energy and heat is characterized by a very high process efficiency of up to 90%. Less fuel is used to produce the same amount of heat and electricity than in the case of separate production. Combined heat and power generation allows more efficient use of fuels and a reduction in global CO2 emissions. Poland, which is the largest coal producer in the European Union, thanks to the use of cogeneration systems using gas from coal deposits, can reduce methane emissions into the atmosphere, which is particularly important in the event of the introduction of emission fees on methane. The study presents the results of an analysis aimed at identifying the risks present in the construction projects of low-power cogeneration systems for various types of enterprises. The author separates the existing risks by the place of origin of the risk (sources of risks) and presents the rationale for installing such a system. Finally, the author presents a SWOT and PEST analysis of the construction of low-power cogeneration systems.

Artykuł poświęcony jest problematyce zarządzania projektami pod kątem efektywnego wykorzystania technik analitycznych. W części wstępnej przybliżono problematykę projektowania i zarządzania procesami oraz nakreślono wymagania względem produktu końcowego (projektu, usługi). W badaniu zweryfikowano hipotezę, że analiza SWOT oraz metoda QFD istotnie przyczyniają się do obniżenia kosztów, skrócenia czasu projektowania oraz wsparcia procesu pogodzenia świata dostawców z oczekiwaniami potencjalnych klientów. W celu weryfikacji hipotezy posłużono się przykładem wdrożenia rozwiązań chmurowych w organizacji (przedsiębiorstwie), gdzie wykorzystano starannie wyselekcjonowane dane uwzględniające pożądane cechy produktu (usługi) zarówno przez projektantów, jak i docelowych odbiorców. W badaniu wykorzystano jako przykład analizę wdrożenia rozwiązań chmurowych w organizacji (przedsiębiorstwie) celem weryfikacji w jakim stopniu narzędzia analityczne są przydatne do wspomagania projektowania tego typu rozwiązań. Przeprowadzenie analizy SWOT wraz z interpretacją tablic krzyżowych jednocześnie z wykorzystaniem metody QFD pozwoliło na wyciągnięcie wniosków, które odpowiadają na pytanie: Czy prezentowane metody mają zastosowanie w procesie decyzyjnym wdrażania rozwiązań chmurowych oraz w jakim stopniu prezentowane techniki analityczne wspierają proces zarządzania, przekładając się na skrócenie czasu i kosztów projektu, eksponują ryzyko oraz wskazują newralgiczne dla organizacji (przedsiębiorstwa) zagrożenia związane z przedmiotowym projektem? Dane wykorzystane w artykule zostały dobrane deterministycznie z pominięciem procesu ankietowania, ponieważ celem artykułu jest zweryfikowanie możliwości wykorzystania prezentowanych technik analitycznych. Współczynniki wagowe cech w analizie SWOT zostały również dobrane obiektywnie metodą jakościową, przy czym myśląc o dalszym rozwoju badań należałoby przeprowadzić ankietę spodziewanych cech produktu (usługi) na odpowiedniej grupie respondentów co pozwoliłoby na zwiększenie wiarygodności wyniku badań. Zastosowana w przedmiotowy badaniach metodologia może zostać zaimplementowana w procesie projektowania podobnych rozwiązań teleinformatycznych.

The article is devoted to the issues of project management in terms of the effective use of analytical techniques. In the introductory part, the issues of designing were presented and process management, and the requirements for the final product (project, service) were outlined. The study verified the hypothesis that the SWOT analysis and the QFD method significantly contribute to reduce costs, shorten design time and support the process ofreconciling the world of suppliers with the expectations of potential customers. In order to verify the hypothesis, an example of the implementation of cloud solutions in an organization (enterprise) was used, where carefully selected data was used, taking into account the desired features of the product (service) by both designers and target recipients. The study used as an example an analysis of the implementation of cloud solutions in an organization (enterprise) in order to verify to what extent analytical tools are useful for supporting the design of such solutions. Conducting a SWOT analysis together with the interpretation of cross tables simultaneously with the use of the QFD method allowed to draw conclusions that answer the question: Whether the presented methods are applicable in the decision-making process of implementing cloud solutions and to what extent the presented analytical techniques support the management process, translating into a reduction in project time and costs, they expose the risk and indicate the critical threats for the organization (enterprise) related to the project in question? The data used in the article were selected deterministically, omitting the survey process, because the purpose of the article is to verify the possibility of using the presented analytical techniques. The weighting coefficients of the features in the SWOT analysis were also selected objectively using the qualitative method, while thinking about further development of the research, a survey of the expected features of the product (service) should be conducted on the appropriate group of respondents, which would allow to increase the credibility of the research results. The methodology used in this research can be implemented in the process of designing similar ICT solutions.

This paper uses a case study of an abandoned magnesite mine in the Limpopo Province of South Africa to ﬁnd ways of identifying post-mining land used from the current uses of the abandoned mine sites or features. The approach used involved carrying out a ﬁeld characterization of the mine site and documentation of the current uses of the features of the abandoned mine site. The technique used to identify the internal and external factors of the land uses involved analyzing their Strength, Weakness, Opportunities, and Threats. The Analytic Hierarchy Process (AHP) technique was used for further ranking of the land uses to identify the most post-mining or rehabilitation land uses for the different parts of the mine. Lastly, the earthwork requirement in reshaping the terrain of the mine to support the selected land uses was estimated from the 3D-terrain models generated from height data collected using a Real-Time Kinematic Geographical Positioning System. The results of the study identiﬁed land use that needs further surface development as the most appropriate for the abandoned Nyala Mine. These land uses demonstrated the potential of addressing the hazards of the mine with the clear promise of improving the socio-economic status of the host communities.

In most settlements of Ukraine there are no existing programs for municipal solid waste management (MSW) and schemes for sanitary cleaning of settlements, there are no registers of waste generation, treatment and disposal and disposal sites, which leads to the formation of landfills, deteriorating sanitation settlements and increase the level of environmental danger in the region. The article presents the results of research that indicate that the existing structure of the MSW management system in Ukraine at the regional level (on the example of Zhytomyr region) is imperfect. It is characterized by fragmentation, disunity and heterogeneity. The peculiarity of the system is the lack of interaction between government agencies, environmental services and the local community, which does not provide a sufficient level of control over the sanitary condition of territories, as well as collection, transportation, disposal and disposal of solid waste. The aim of the study is to strategically analyze the preconditions for the implementation of municipal solid waste management systems to increase the level of environmental safety in the united territorial communities through the introduction of environmental logistics and crowdsourcing mechanisms. The methodological basis for assessing and selecting methods and ways to improve the environmental safety of the study region by improving the waste management system (hereinafter - waste management) is a systematic approach that allows analysis of the problem and ensures search efficiency for management decisions. The SWOT and PEST analysis identified the strengths and weaknesses of the existing waste management system and the prerequisites for the implementation of a modern system of solid waste management. The increase in the number of business structures that are ready and able to implement modern methods of waste disposal and identified the availability of modern innovative management methods in public authorities and local governments. However, the low efficiency of the existing waste management system, the lack of communication and coordination of actions between stakeholders in solving the problem pose a threat to maintaining the environmental security of the region.

The research aims to recognize the potential of adopting the model-based design methodology to the development process of an LPG (liquefied petroleum gas) fuelling system. Changing regulations often force the modern development of internal combustion engines (Euro 7, CO2 reduction measures, etc.). With the definitive ban on new registrations of vehicles powered by internal combustion engines in Europe (planned for 2035), there is still ongoing development of the adaptation of the fuelling system to LPG. There is still market potential in adapting new internal combustion engines, usually equipped with direct injection systems, to reduce customers’ cost of ownership of a vehicle. As the engineering process should be accelerated in the face of the variety of direct injection systems offered by OEMs (original equipment manufacturers), the model-based design methodology is proposed to make the development more effective. The article presents the SWOT analysis of this approach in the engineering process and the potential of the method in an LPG system development is concluded.

Purpose: The study aimed to locate and identify weak areas in the technological process of the aluminium piston, where the occurrence of events with significant risk could interfere with its proper course and meet the customer's requirements. Design/methodology/approach: One of the production lines on which the aluminium pistons are produced was chosen for the test. Risk identification within the process was carried out through the implementation of a simplified SWOT analysis, development of the process risk structure taking into account the identified opportunities and threats and development of a matrix for responding to key risks identified in the risk structure. Findings: The three most significant risks were identified: failure to meet customer requirements, delays in delivery of castings, forgings, components and errors in monthly production plans, as well as increased process costs. The most effective actions concerning the risks under consideration turned out to be: drawing up detailed records in the description of the subject of the contract, as well as additional supervision and inter-operational controls and performing detailed analysis of the documentation before the beginning of the contract. Research limitations/implications: In order to reduce the risks as part of the technological process, remedial actions and a response plan are proposed. Practical implications: Future research will be carried out within the remaining technological processes within the company. The methodology presented should be applied to companies that are committed to responsible risk management. Originality/value: The study is a useful material for manufacturing companies indicating a comprehensive methodology for identifying key risks within technological processes.

The purpose of this paper was to assess the possibility of using modern technologies, virtual reality (VR) and augmented reality (AR), to study the evacuation of passengers from ships. The evacuation of passengers from ships is usually studied from post-accident reports, laboratory or field experiments, and/or numerical modelling. Nowadays, with the rapid development of computer resources and wearable technology, evacuation can also be studied using VR or AR. The methods used in this paper for such assessments included a literature review (tools like Web of Science, Scopus, and Google Scholar indexing platforms) and comparative strengths, weaknesses, opportunities, threats (SWOT) analysis. The results demonstrated the great potential for the implementation of VR and AR technologies within the shipping industry, similar to how they have already found applications in the research of pedestrian evacuation from buildings or open spaces. Finally, recommendations for their use in ship passenger evacuation are presented.

Small and medium-sized enterprises (SMEs) are facing barriers to grow due to the lack of structured procedures for upgrading and allocating the limited resources. To overcome these drawbacks and to improve business capabilities, a structured framework to conduct a comprehensive diagnostic and upgrading study is presented in this paper. The proposed framework involves four phases. First, the external and internal strategic factors, which can affect the enterprises’ performance are evaluated using strategic planning and assessment tools. Second, key upgrade performance indicators are developed and evaluated using multi-attribute rating techniques to guide, evaluate, and track progress of upgrading process. Third, a set of upgrade strategies are generated and evaluated using resource allocation model. Finally, a periodic re-evaluation plan is introduced to monitor the implementation progress. The developed framework for performance evaluation and upgrading is suitable to be used as a structured know-how procedure in manufacturing enterprises and can support entrepreneurs in their strategic decisions. To validate the proposed framework, a data set was collected from a local housecore company. As a result, one package of the efficient frontier strategies that represents the best use of resources was proposed for implementation.

The paper concerns evaluation of the exploitation of the world’s water resources for irrigating field crops. It was determined that the volume of water used in 2020 in all sectors of the economy in relation to the world’s freshwater resources will amount to 31 to 38% of the available resources. It has been found that globally, in the period 1900–2100, the agricultural sector has the highest consumption of fresh water. Therefore, there is a need for rational use of water, especially when irrigating field crops. Hence, the paper describes the methods of evaluating the effectiveness of irrigation. The indicators from the Water use efficiency group, which consider the yield obtained from a given area and the sum of irrigation doses, were considered the most reliable form of evaluation. Determining the indicator should also be accompanied by a presentation of the scope of work related to irrigation, water quality, cultivation techniques, fertilization and environmental conditions of the growing season. The work characterizes the selected pressure irrigation systems, considering their advantages and disadvantages. On this basis, the paper presents the adaptation of the SWOT analysis for two irrigation systems: a reel sprinkler with a water cannon and a drip tape.

With the development of information technology, the improvement of production processes and lifestyles, and the transformation of commercial economic models, the traditional agricultural industry cannot meet the increasing material and cultural needs of villagers. Therefore, the development of traditional tourist villages has transformed into being based on ecological engineering and sustainable development. The starting point of the existence of such tourist villages will be the protection and development of traditional villages. At the same time, the village space is the material carrier for the development of rural tourism, and the construction of a spatial form that is compatible with the tourism resource utilization model can effectively promote the development of rural tourism. Based on SWOT analysis, this article carefully analyses and summarises the domestic research on the sustainable development of tourist villages. The results show that such sustainable development effectively avoids the excessive development of resource elements during rural construction, which can lead to waste, and promotes the optimal use of resources. Since rural tourism has taken a sustainable development path, the average annual compound growth rate has reached as high as 31.2 %, which is considered very rapid growth. Tourist operating income has reached more than 30 %. It is expected that the national rural tourism income in 2021 will exceed 10,000 trillion yuan. Tourism villages will continue to consider ecological engineering and sustainable development as the starting point for promoting the development of rural tourism in China, popularising consumption, standardising services, diversifying benefits, and making products unique.
