EN

Experience-based research in architecture aimed at perfecting design praxis typically begins with an informed identification of the problem and goal. It therefore becomes necessary to postulate a verification of assessment criteria by introducing a verification and revision mechanism into their formulation. Correct – relevant – solutions are those which meet assessment criteria, which means that the assessments of the modification problem solutions comply with the pattern produced by the solution. In unique cases, as they are cases with the most severe consequences, criteria need to be formulated on a case-specific basis. The author wishes to describe this property, namely to define the sense of relevance as an attribute of research.

PL

Badania w architekturze nacelowane na doskonalenie praktyki projektowej te oparte na doświadczeniu, zwykle rozpoczynają się od świadomej identyfikacji problemu i celu. Z tego też względu niezbędne staje się sformułowanie postulatu weryfikacji kryteriów oceny przez wprowadzenie do procesu ich formułowania mechanizmu weryfikacyjno-korygującego. Za rozwiązania poprawne – relewantne uważa się te rozwiązania, które odpowiadają kryteriom oceny, co znaczy, że oceny rozwiązania problemu modyfikacyjnego są zgodne z wzorcem danym przez rozwiązanie. W przypadkach niepowtarzalnych, jako że one właśnie są przypadkami o najpoważniejszych konsekwencjach, kryteria muszą być formułowane indywidualnie. To, co autor chce zrobić, to opisać tę właściwość, tzn. zdefiniować sens relewancji, jako atrybutu badań.

Multi-criteria decision-making (MCDM) methods have been implemented in many fields. In the meantime, several methods have been proposed to obtain the weight of the criteria determined by various methods in different ways. In this paper, a new approach, called simultaneous interpretive structural modelling and weighting (SISMW), is proposed to solve a multi-criterion decision-making (MCDM) problem. Using SISMW, the weight of the criteria and the relationship between them could be determined simultaneously. In this approach, like the ISM method, pair comparison between criteria was made by the decision-maker to determine the relationships among the different criteria. With the help of this data, the weight of the criteria, as well as the causal (cause and effect) relationships between them, were determined in 12 steps. The main advantage of this method is that only one stage of data collection is required for obtaining weights and modelling, and so the research process may be faster. This may increase the reliability of the collected data because, in a one-step survey, the impact of time is minimized. This process can be useful for conceptualizing and developing theories to help decisionmakers understand the problem better.

This study employed viable methods for the selection of a preeminent mooring line amongst other alternatives for the mooring of a floating wave energy converter (WEC) in shallow waters. Conventional mooring lines for WEC mooring are identified for an optimal selection exercise. A combination of the Entropy Weight and Visekriterijumska Optimizacijia I Kompromisno Resenje (VIKOR) methods is utilized in the aforementioned exercise. The two methods are effectively used in an assessment of the attributes and performance of various mooring lines in practical application. The result obtained demonstrated that a steel wire rope is the best mooring line suitable for WEC system operations. It constitutes a good reference to marine and offshore engineering industries in decision making related to optimal mooring lines suitable for the mooring of a WEC system in shallow waters.

The feedback of international practice shown that the installation of photovoltaic (PV) parc on the dumps is one of the best environmental and economic solutions. However, the number of projects is still very limited comparing to the identified potential. This paper addresses site selection criteria for landfill PV installation, particularly in relation to mining hazards. For installing the PV, different environmental, technical and economic criteria should be respected. The slope of the dumps appears as the main constraint for the installation of photovoltaic panels. In addition, specific foundation systems should be considered to ensure long-terms safety and security. The paper presents several examples of installation of photovoltaic panels on coal-lignite dumps in France.

Praktyka międzynarodowa wykazała, że instalacja parku fotowoltaicznego (PV) na zwałowiskach jest jednym z najlepszych ekologicznych i ekonomicznych rozwiązań. Liczba projektów jest jednak nadal bardzo ograniczona w stosunku do zidentyfikowanego potencjału. W artykule omówiono kryteria wyboru lokalizacji dla instalacji fotowoltaicznej na zwałowisku, w szczególności w odniesieniu do zagrożeń górniczych. W przypadku instalacji fotowoltaicznej należy mieć na uwadze różne kryteria środowiskowe, techniczne i ekonomiczne. Nachylenie zboczy zwałowiska wydaje się być głównym ograniczeniem dla instalacji paneli fotowoltaicznych. Ponadto, aby zapewnić długoterminowe bezpieczeństwo i ochronę, należy rozważyć specjalne systemy fundamentów. W artykule przedstawiono kilka przykładów instalacji paneli fotowoltaicznych na zwałowiskach powstałych po eksploatacji węgla we Francji.

The article aims to evaluate criteria that should be considered when deciding on the adaptive reuse of existing buildings. Reusing a building by means of renovation is in line with the concept of sustainability, as it makes it possible to extend the useful life of a building without incurring significant financial expenses. The concept is related to the theory of the circular economy, which maintains that by designing a system of closed-loop processes – in which waste from one process is used as raw material for another – the consumption of raw materials, the amount of waste and energy losses can be minimised. The article discusses criteria that local governments, municipalities, architects, and designers should consider when deciding whether to reuse a building. The criteria were classified as technical, economic, social, spatial and environmental. To achieve the main objective, we looked into the preferences of current and potential practitioners who might be involved in the adaptive reuse of buildings with regard to the criteria. The most significant criteria were validated using a survey method.

Celem artykułu jest ocena kryteriów, które są brane pod uwagę przy podejmowaniu decyzji o adaptacyjnym, ponownym wykorzystaniu istniejących budynków. Ponowne wykorzystanie istniejących obiektów budowlanych poprzez ich modernizację i przystosowanie do nowych warunków użytkowania jest zgodne z koncepcją zrównoważonego rozwoju, ponieważ umożliwia przedłużenie okresu ich użytkowania bez ponoszenia znacznych nakładów finansowych. Koncepcja adaptacyjnego wykorzystania istniejących budynków związana jest z teorią gospodarki o obiegu zamkniętym, według której obiekty budowlane należy projektować i budować uwzględniając procesy, w którym odpady z jednego procesu są wykorzystywane jako surowiec do innego. Ogranicza się wówczas zużycie surowców, zmniejsza ilość odpadów i minimalizuje zużycie energii. W artykule omówiono kryteria, którymi powinny kierować się samorządy, architekci i projektanci przy podejmowaniu decyzji o ponownym wykorzystaniu budynku. Kryteria zostały sklasyfikowane jako kryteria techniczne, ekonomiczne, społeczne i środowiskowe. W artykule przedstawiono, zweryfikowane metodą ankietową, preferencje obecnych i przyszłych decydentów, którzy są zaangażowani w adaptacyjne ponowne wykorzystanie obiektów budowalnych.

For decades, the positioning of the sites of the extraction of materials was based, on the economic profit, (existence and abundance of the deposit, proximity of the basins of consumption) and the social aspect (number of jobs created), the environmental dimension was little or not taken into account. However, because of the negative impacts of this industry, more and more felt by the population, and in addition to the awareness of the protection of the environment, decision-makers have been forced to rethink their decision-making policies. Thus, it has become necessary to adopt sustainable management of this sector, taking into account environmental, social and economic issues. In this context, the presented work proposed the mathematical method of decision-making MACBETH (Measuring Attractiveness by a Categorical Based Evaluation Technique). This approach is based on economic, social, and environmental criteria, which have been chosen concerning sustainable development issues. The selection of options reflects the geographical distribution as well as the typology of materials at the level of the study area. Then, the attractiveness of the options on each weighted criterion was evaluated following the preferences presented by the decision-makers and finally their aggregation by the MACBETH tool. The implementation of this tool made it possible to evaluate the exploitation of existing quarries at the study area level and to predict the optimization of future locations.

The article describes optimization of the process of acceleration of the tower crane trolley movement mechanism during the steady mode of the slewing mechanism. A mathematical model of the boom system of the tower crane was used for the optimization of the trolley movement. The model was reduced to a sixth-order linear differential equation with constant coefficients, which represents the relationships between the drive torque and the coordinate of the load and its time derivatives. Non-dimensional complex criterion (objective function), which takes into account the drive torque and its rate of change in time during the transient process, was developed to optimize the mode of the trolley movement mechanism. Based on that, a variational problem was formulated and solved in an analytical form in which root-mean-square (RMS) values of the quantiles were applied. A complex optimal mode of acceleration of the trolley movement mechanism was obtained and compared with the modes optimized based on different criteria. Advantages and disadvantages of the solutions were discussed based on the analysis of the obtained optimal modes of motion. The analysis revealed low- and high-frequency elements oscillations of the trolley movement mechanism during the transient processes. The conditions for their elimination were formulated.

Analiza wielokryterialna jest często stosowaną metodą wyboru optymalnego rozwiązania przedsięwzięcia. W prezentowanej analizie zastosowano cztery kryteria: funkcjonalno-ruchowe, kosztowe, środowiskowe i społeczne oraz możliwości etapowania. Analiza wrażliwości jest prostą techniką analityczną pozwalającą na badanie wpływu zmiany kryteriów analizy wielokryterialnej na ostateczny wynik wyboru koncepcji. Analiza odpowiada na pytanie czy wybrany wariant przedsięwzięcia jest „stabilny”, tzn. odporny na zmianę wcześniej założonych kryteriów. Analiza przepustowości pozwala ustalić poziom swobody ruchu i wyznaczyć liczbę pasów ruchu.

EN

Multi-criteria analysis is a common method of choosing the optimal solution for specific project. Four criteria were used here: functional-utility, cost, environmental and social, and staged capabilities. Sensitivity analysis is a simple analytical technique that allows to study the impact of changing the criteria of multi-criteria analysis on the final outcome of the concept selection. It answers the question whether the chosen option of the project is “stable”, that is resistant to the change of previously established criteria. Capacity analysis allows to determine the level of service and the number of lanes.

Taking as an example the very interesting and moti vating paper by Sousa Ribeiro et al. (2021) an attempt is made of providing a couple of insights into the decision making process from the point of view of the potentially helpful aspects of data analysis and OR-related modelling. These are just hints and suggestions, meant primarily to emphasise the multifaceted character of the decision making situations and processes, especially when concerning more complex issues. While the course of the procedure proposed and exemplified in Sousa Ribeiro et al. (2021) is treated as fully correctly and successfully carried out to the end, we wish to show the potential use of information, constituting in a sense a “by-product” of such a procedure, or, actually, of any similar procedure, aimed at supporting decision making.

The suitability of a land plot in a real estate market could be identified as a good investment because the land plot is deemed as popular. This activity is important for economic growth, who is one of the sustainable development goals. Mostly, all research in this field is focused on sustainability as well as the opinions of professionals. However, this field should be explored from another side which is based on real geodata. Criteria and its weight are very important in decision support systems. The correct criteria can help in selection of the best real estate object for an investment, but it is not only useful but also and a challenging task that has not yet been solved. The methods of research are data graphical analysis, correlation, decision supporting systems, etc. The research aims at determining the significance of the connections and using them as the criteria in the selected decision supporting method. In addition, it will be determined which decision supporting method defines the most suitable object for investment. These new criteria are proposed for operation in the land use models. Furthermore, it has been identified as one criterion, which is significant in the urban and agrarian territories. Also it turned out, that the land plot is the most active when it is as far from a densely built-up residential territory as possible and as close to a school, and when the land plot is as large as possible.

Hałas jako stresor może przyczyniać się do rozwoju różnego typu chorób, powodować rozproszenie uwagi, utrudniać pracę i zmniejszać wydajność pracowników. Elementy wyposażenia technicznego budynku, jak również urządzenia biurowe mogą emitować wyraźne dźwięki o charakterze tonalnym. Powszechne występowanie tych urządzeń w środowisku pracy przekłada się potencjalnie nawet na kilkaset tysięcy stanowisk pracy w Polsce. Liczne doniesienia literaturowe wskazują, że uciążliwość hałasu tonalnego oceniana subiektywnie jest większa niż hałasu szerokopasmowego. W ocenie środowiska pracy brak jest kryteriów dotyczących hałasu tonalnego zarówno w pomieszczeniach (normy budowlane), jak i w zakresie hałasu na stanowiskach pracy (ocena pod względem uciążliwości). W artykule dokonano przeglądu istniejących przepisów, przeanalizowano dane literaturowe oraz podano wyniki badań prowadzonych w CIOP-PIB w zakresie uciążliwości hałasu tonalnego.

The paper deals with the optimization of production processes and the setting of criteria for reducing production costs. Any company is not just a leap in production, but a lean has to be gradually transferred to all its activities. This created the concept of a lean company first. The skill of an enterprise is to perform only the activities that are needed, to do them right for the first time, to make them faster than others and to spend less resources at the same time. The company's business is that the company does exactly what the customer wants, with a minimum number of activities that do not add value to the product or service. The Lean Production System focuses mainly on eliminating waste in every activity of the manufacturing enterprise.
