    An Application of Fuzzy Integrated Model in Green Supplier Selection
    (Hindawi Limited, 2019) Ulutaş A.; Topal A.; Bakhat R.
    "Sustainability" term has not only become increasingly important globally for individual companies, but also become important for whole supply chains. The selection of supplier is a significant decision for the sustainability of supply chains. Literature review revealed that supplier selection is made traditionally based on economic attributes which are insufficient for sustainability of supply chains as sustainability requires taking economic, environmental, and social issues into account. For this purpose, this paper proposes determining the green supplier selection attributes and then developing a methodology for assessment and ranking of green suppliers based on determined attributes. The first contribution of this study is to propose a novel method, which is FROV (fuzzy extension of range of value) to literature. The latter is to utilize fuzzy extension of preference selection index (FPSI) to identify the weights of attributes. The third is to develop a novel fuzzy multiattribute decision-making model consisting of FPSI and FROV to determine the best supplier for a Turkish textile company. © 2019 Alptekin Ulutaş et al.

    The selection of the best olympic place for Turkey using an integrated mcdm model
    (Growing Science, 2019) Karaca C.; Ulutaş A.; Yamaner G.; Topal A.
    Hosting Olympic Games is a significant opportunity for every country and her metropolitan cities. Olympics offer several benefits to the Host countries and cities such as introducing cultural assets of the country to the world and increasing economic value of the country and city Olympics held. Countries and cities wishing to host Olympic Games have to prove that they have the qualifications to be host of these games. The International Olympic Committee (IOC) has identified 5 main criteria and 22 sub-criteria to determine the objectivity measure of this adequacy. These criteria are in conflict with each other so multi-criteria decision making (MCDM) methods can be useful to determine the best host country and its city for Olympic Games. In this study, an integrated MCDM model is proposed to determine the best metropolitan city in Turkey for hosting of the Olympic Games. The contribution of this study is that there are very few studies related to the selection of hosting places for Olympic Games using MCDM methods. The results of the integrated model show that Antalya is the best metropolitan host for Olympic Games. © 2018 by the authors; licensee Growing Science, Canada.
