    Opis:
    Research background: Immigrant entrepreneurship remains a key issue for researchers, politicians, and policymakers. It has been widely discussed from different angles among various researchers in recent studies ? particularly in Europe. However, there is a lack of studies to present the motivation of the causal relationship between immigrant entrepreneurs. Purpose of the article: This study aims to fill the gap and analyze the causal relationship between the motivations of Asian immigrant entrepreneurs in Germany. Methods: The study was conducted through a face-to-face interview using a predesigned questionnaire from Asian business owners in Germany and the Decision-Making Trial and Evaluation Laboratory (DEMATEL) approach was applied to analyze the data. Findings & value added: The results show that capital acquisition, employment, financial problems in the family, and existence opportunities in the market are the factors that have higher priority, and may highly impact the Asian immigrant entrepreneurial decision. On the other hand, relatives or social networks remain the lowest priority factor that encourages Asian immigrants towards self-employment. The study has also found that entrepreneurship in the family, the state support policy for immigrants, low level of education, unfamiliarity with the local language, and dissatisfaction with the previous job belong to the cause group. However, some of the motivating factors relate to the effect group, such as capital acquisition, opportunity in the market, immigrant community ties or social networks, unemployment, and financial problems in the family. The most affected factor among the effect group is unemployment, while immigrant community ties or social network is the least affected factor. This study includes a novel interpretation of the DEMATEL approach that researchers have not yet addressed; therefore, it is highly relevant for policymakers, especially those interested in migration studies. Finding out the main driving forces behind Asian immigrant entrepreneurs in a developed European nation like Germany and how these drivers affect cause-and-effect interactions between them are the contributions that add value to the field.

    Opis:
    Ships have an important role in among the factors causing marine pollution. Marine pollution by ships damages sea life, which effects human health indirectly, in addition it restricts usage of sea for different purposes. Increasing comprehensive and compelling liabilities related with environmental components and subjects day by day are expected results for environmental science and engineering applications according to 60% of our responsibilities of European Union Integration development. In today’s’ world, where global warming is an issue of high priority and makes us feel its impacts in our lives, leaving a livable world to the next generations is now a primary goal for all. Determination of marine pollution caused by ship operations issue is a multiple criteria decision-making (MCDM) problem, and requires MCDM methods to solve it. Therefore, the role of ship factor in maritime pollution and the possible reasons of this argument can be quantitatively evaluated based on expert knowledge and MCDM methodology. To investigate what makes to reduce the first “caused by ship operations " in marine pollution, the decision-making trial and evaluation laboratory (DEMATEL) method approach was applied in this study.

    Opis:
    Modelling of a decision-maker’s preferences in multi-criteria decision analysis is performed using weights that reflect the relative importance of the given decision criteria. The determination of accurate values of the weights is therefore of considerable importance. Numerous means and methods are used for this purpose, such as: the entropy method (i.e., the method of objective weights), the Simos method, the SWARA method, the ANP or AHP methods, and many others. This paper analyses the DEMATEL method, frequently used to identify cause-and-effect relationships. Nowadays, it is often used in multi-criteria decision analyses. In the opinion of some authors, DEMATEL may be useful also to determine the weights of criteria. However, the approach presented by these authors has certain drawbacks. The present paper proposes a different approach to the weighting procedure using DEMATEL. Using numerical examples, it also presents weights determined by this method and compared to those obtained using the AHP method.

    Expert cause and effect analysis of the failure of historical structures taking into account factors that are difficult to measure

    Opis:
    The protection of Polish architectural heritage in the former eastern borderlands, accomplished through the conservation and technical securing of historical structures, constitutes one of the main programmes that are implemented by the Ministry of Culture and National Heritage. Currently, many Polish historical buildings in the former eastern borderlands are in a very bad technical condition. The load-bearing systems of these elements, as well as elements of their finish, require immediate emergency securing work. The basic steps that precede conservation work are emergency structural works, which guarantee the durability and stability of the entire historical substance. The specifics and complexity of the problem of the failure of historical buildings often demands an in-depth analysis of a series of factors that are difficult to measure and which are responsible for the cause and effect relationship during the early stage of the technical evaluation of a structure. The analyses of failures of numerous historical structures, for instance that were carried out by the authors, have become the inspiration for the search for effective methods of analysis that would allow for an in-depth analysis of the causes and effects of the failures in question. The DEMATEL method (Decision Making Trial and Evaluation Laboratory) that has been presented in this work, and its fuzzy extension, has lately become one of the more popular methods used in the cause-and-effect analysis of various phenomena. The authors demonstrated how this method works on the example of the evaluation and securing of the load-bearing system of the XVII Collegiate church of the Holy Trinity in the town of Olykha in the Volhynskiy Oblast, Ukraine.
    W artykule przedstawione zostało zagadnienie związane z analizą przyczynowo-skutkową awarii obiektów zabytkowych z uwzględnieniem czynników trudnomierzalnych. Przeprowadzone przez autorów artykułu analizy uszkodzeń wielu obiektów zabytkowych stały się przyczynkiem do poszukiwania efektywnych metod analizy, które pozwolą na wstępną, wnikliwą identyfikację przyczyn i skutków związanych z awarią tego typu obiektów. Zaproponowana w pracy metoda DEMATEL (Fuzzy Decision Making Trial and Evaluation Laboratory) jest ostatnio jedną z bardziej popularnych metod używanych do analizy przyczynowo-skutkowej różnych zjawisk. Metoda ta zdaniem autorów niniejszego artykułu jest właściwym narzędziem służącym do analizy zawartego w pracy problemu technicznego. W literaturze można znaleźć wiele przykładów zastosowania metody DEMETEL do analizy zjawisk przyczynowo skutkowych w budownictwie np. [5,6,7]. W powyższych pozycjach nie uwzględnia się jednak niepewności ocen eksperckich, która w przypadku badania zjawisk trudnomierzalnych zachodzących w obiekcie zabytkowym jest istotna. Dlatego w celu uwzględnienia w analizie niepewności eksperckich ocen oraz agregacji rozbieżnych opinii autorzy niniejszego artykułu zaproponowali zastosowanie rozmytego rozszerzenia [3,9] metody DEMATEL poprzez wprowadzenie do jej algorytmu elementów logiki rozmytej [10,17,18,19]. Działanie powyższej metody autorzy zademonstrowali na przykładzie oceny i zabezpieczenia ustroju nośnego XVII wiecznej Kolegiaty p.w. Św. Trójcy w miejscowości Ołyka w Obwodzie Wołyńskim na Ukrainie.
