STUDY TOWARDS THE TIME-BASED MCDA RANKING ANALYSIS – A SUPPLIER SELECTION CASE STUDY

Decision-making processes increasingly use models based on various methods to ensure professional analysis and evaluation of the considered alternatives. However, the abundance of these methods makes it difficult to choose the proper method to solve a given problem. Also, it is worth noting whether different results can be obtained using different methods within a single decision problem. In this paper, we used three selected Multi-Criteria Decision Analysis (MCDA) methods called COMET, TOPSIS, and SPOTIS in order to examine how the obtained rankings vary. The selection of material suppliers was taken into consideration. The equal weights, entropy and standard deviation methods were used to determine the weights for criteria. Final preferences values were then compared with the WS similarity coefficient and weighted Spearman correlation coefficient to check the similarity of the received rankings. It was noticed that in the given problem, all of the methods provide highly correlated results, and the obtained positional rankings are not significantly different. However, practical conclusions indicate the need to look for improved solutions in the correct and accurate assessment of suppliers in a given period

Less is enough. Culture of moderation in conceptual plein-air convention of the 1970s in Poland

The aim of this text is to analyse the conceptual plein-air convention of the 1970s as an example of practising moderation in the history of Polish culture. Conceptual plein-air meetings are shown as a great example of moderate artistic activity as well as an inspiration for creating and developing the idea of a moderate and good life in the present times. The first section of the article places the latter in the context of a broader debate on the climate crisis while calling for degrowth and moderation. The second part presents the artistic and social context of conceptual plein-air convention, highlighting the links between the limits to growth, criticism of development and technical advancement, and conceptual art. The third section analyses conceptual plein-air convention as a scenario for reflection on moderation and its practising in artistic creation. It also discusses the relevant – moderate – aspects of the 1971 Plein-Air Convention in the Zgorzelec Land and the 1972 Plein-Air Convention in Osieki, Poland. The authors conclude by emphasising the usability of the conceptual plein-air model as a tool for learning and practising the culture of moderation in modern times

Sztuka umiaru. Wizje dewzrostowych instytucji sztuki

The aim of this article is to indicate and consider the propositions of reforming art institutions formulated by artists, which are close to the spirit and values of degrowth theories and practices. We claim that art and culture can play an important role in the posited degrowth transformation of the society, serving as tools providing the language, narratives, images, and imagination that support abandoning the dominating growth paradigm. As we show in the text, artists from Western Europe and the USA have been proposing to transform art institutions in the spirit of degrowth at least since the 1960s and 1970s. Many of them postulate that the institutions should abandon the voracious art consumption and production as well as rivalry in favor of developing sensitivity and social relations, escaping commodification and museification as well as ecologizing the imagination. In this article, we consider three models of such an institutional transformation: giving up the production of art, care work and reclaiming play and disposable time. We refer to a number of historical and contemporary art practices to show how each of the models implements the postulates of degrowth theories and practices, becomes a carrier of the values related to the culture of re-straint. We also discuss the different visions regarding degrowth galleries and museums of the future implied by each model. In the face of the contemporary tangle of crises, and especially the climate crisis, reforming art institutions in the spirit of degrowth seems necessary and the models we have considered should not be treated as metaphors but rather exercises in adapting to the changing con-ditions of living on Earth.Celem niniejszego artykułu jest wskazanie i omówienie formułowanych przez artystki i artystów propozycji reformy instytucji sztuki w duchu wartości bliskich teoriom i praktykom dewzrostowym. Twierdzimy, że sztuka i kulturą mogą pełnić istotną rolę w dewzrostowej transformacji społecznej jako narzędzia dostarczające języka, narracji, obrazów i wyobraźni wspierających dążenia do odejścia od dominującego paradygmatu wzrostu. Jak pokazujemy, artystki i artyści z Europy Zachodniej i USA co najmniej od przełomu lat sześćdziesiątych i siedemdziesiątych proponują reformy instytucji sztuki w duchu dewzrostowym: postulują odejście od zachłannej produkcji i konsumpcji sztuki oraz rywalizacji na rzecz rozwijania wrażliwości i relacji społecznych, ucieczki od utowarowienia i muzeifikacji oraz ekologizowania wyobraźni. W artykule omawiamy trzy modele tego rodzaju transformacji instytucji: zaniechanie produkcji sztuki, pracę opieki oraz odzyskiwanie zabawy i czasu wolnego. Powołując się na przykłady historycznych i współczesnych działań artystycznych, wskazujemy w jaki sposób każdy z modeli realizuje postulaty dewzrostu, jak staje się nośnikiem wartości kultury umiaru oraz jaką wizję dewzrostowych muzeów i galerii przyszłości wyraża. W obliczu splotu kryzysów współczesności, w tym szczególnie kryzysu klimatycznego, reforma instytucji sztuki w duchu dewzrostu wydaje się konieczna, a omówione przez nas artystyczne propozycje należy traktować nie jako metafory, lecz ćwiczenia z przystosowywania się do zmieniających się warunków życia na Ziemi
