Öğe Alternatif tedarikçilerin bulanık TOPSIS yöntemi ile karşılaştırılması: Hazır beton sektöründe bir uygulama(Malatya Turgut Özal Üniversitesi, 2020) Koç, ErdinçTedarikçi seçim problemi çok kriterli karar verme problemleri arasında kabul edilmektedir. Birden fazla tercih alternatifinin bulunduğu problemler birbirleriyle çelişen karar kriterlerine sahiptir. Tedarikçi seçimi üreticilerin alternatifler arasında en uygun tedarikçiyi seçmelerini gerektiren önemli bir süreçtir; çünkü uygun tedarikçi ürünün maliyeti, müşterinin teslimat süresi, kalitesi gibi unsurlara doğrudan etki etmektedir. Bu çalışmada hazır beton sektöründe faaliyet gösteren dört üretici ile görüşülerek kriterler ve alternatifler değerlendirilmiştir. Karar alıcıların dilsel belirsizliklerini en aza indirgeyecek bulanık sayılar çok kriterli karar verme yöntemlerinden topsis ile birleştirilerek bulanık topsis yöntemi ile probleme çözüm aranmıştır. Tedarikçi seçim problemi sonucunda dört alternatif sıralanarak en uygun alternatif belirtilmiştir.Öğe Can innovation orientation and service provider experience gain competitive advantage to firms?(IGI Global, 2023) Koç, Erdinç; Isgüzar, SedaHaving a competitive advantage is vital for companies trying to survive in an intensely competitive environment. In this study, the effect of innovation orientation and service provider experience on competitive advantage, which is examined in the context of resource-based view and relational view theory, is examined. Data have been collected from the top managers of 222 firms operating in the tourism sector in Turkey. The findings showed that innovation orientation and service provider experience increased competitive advantage. At the same time, it has been observed that the competitive advantage increases as the service provider experience increases. Finally, it has found that service provider experience has a mediating role in the relationship between innovation orientation and competitive advantage. The study is important in terms of revealing that the use of different competitive strategies together produces good results in the process of discovering different strategic elements that can provide sustainable competitive advantage. © 2023 by IGI Global.

Therefore, it is necessary to understand the factors that affect service innovation. In the few studies conducted on different sectors, the relationship between co-production and IT and service innovation has been tried to be tested separately. In this study, the mediating role of co-production in the effect of information technologies on service innovation in the tourism sector has been investigated. In this way, it will contribute to the literature by investigating the effect of IT (directly and indirectly) and co-production (directly) on service innovation in the tourism sector. In the study data collected from 222 hotel managers were firstly subjected to validity and reliability analysis. Then, mediation analysis was applied within the scope of hypothesis tests. According to the results obtained, co-production has a mediating role in this relationship. In the study, it was concluded that the IT capabilities of the hotels enable them to create service innovations through production together with online travel agencies. © 2022, Universidad de Huelva.
