ÖZEkonomik ve teknolojik gelişmelerin yarattığı değişim ve küreselleşme sonucunda tüm sektörleri etkisi altına alan rekabet ortamı hizmet sektöründe de yaşanmaktadır. İşletmelerin bu rekabet ortamında var olabilmeleri için ürettikleri ürün ve hizmetlerin kaliteli olması çok önemlidir.Bu çalışmada Türkiye'de faaliyet gösteren üç GSM operatörünün hizmet kalitesinin ölçülmesi amaçlan-mıştır. Bu bağlamda öncelikle hizmet kalitesi boyutlarının önem dereceleri uzman gruba uygulanan anketler neticesinde Analitik Hiyerarşi Süreci (AHS) yaklaşımı ile belirlenmiştir. Hizmet kalitesi performansı açısından GSM operatörlerinin sıralanması için Karadeniz Teknik Üniversitesi İktisadi ve İdari Bilimler Fakültesi öğrencilerine uygulanan anketler çok kriterli karar verme tekniklerinden ELECTRE I VE PROMETHEE yöntemleri ile değerlendirilmiştir. Elde edilen sonuçlara göre hizmet kalitesi performansı en yüksek GSM operatörünün "B" firması olduğu tespit edilmiştir.Anahtar Kelimeler: Hizmet Kalitesi, GSM Operatörleri, ELECTRE I, PROMETHEE JEL Sınıflandırması: C44, L96 ASSESSING THE SERVICE QUALITY OF GSM OPERATORS BY ELECTRE I AND PROMETHEE METHODS ABSTRACTThe competitive environment which affects all the sectors as a result of globalization and improvements created by technological, economic and change factors is experienced also in the service sector. Enterprises that want to exist in this competing ambiance have to produce products and service in quality.In this thesis, the aim is to measure the service quality of the three GSM operators that rustle in Turkey. In this context, firstly level of significance of service quality dimensions are determined with the Analytic Hierarchy Process approach as a consequence of the surveys which are applied to expert team. After the level of significance determined, as a result of the surveys that are applied to students at Karadeniz Tecnical University Faculty of Economics and Administrative Sciences, the service quality of GSM operators is assessed by ELECTRE and PROMETHEE methods which are widely used multi critearia decision methods. Accourding to the results it is ascertained that the GSM operator "B" has the best performance of service quality
Bu çalışmada yurt içi turistik turlar, yurt dışı turları ve yurt içi kültür turları açısından kişilerin seçim kararını etkileyen faktörlerin belirlenmesi ve ardından tatil alternatiflerinin öncelik bakımından sıralanması amaçlanmıştır. Bu bağlamda öncelikle faktörlerin ağırlıkları Analitik Hiyerarşi Süreci (AHS) yaklaşımıy-la hesaplanmış, alternatiflerin sıralanması için ise Bulanık PROMETHEE yöntemi kullanılmıştır. Elde edilen sonuçlara göre destinasyon seçiminde en önemli kriterin değişiklik arayışı olduğu belirlenirken faktörler açısından en çok tercih edilen alternatifin yurt dışı turlar olduğu ortaya çıkmıştır.Anahtar Kelimeler: Destinasyon, Analitik Hiyerarşi Süreci, Bulanık PROMETHEE JEL Sınıflandırması: C44, L83 ASSESSING THE LEVEL OF SIGNIFICANCE OF THE FACTORS AF-FECTING THE CHOICE OF DESTINATION AND SELECTING THE CONVENIENT DESTINATION WITH AHP AND FUZZY PROMETHEE METHODS ABSTRACTTourism is a sector that is the most growing and generating revenue in recent years. As the other countries in the world, Turkey makes a point of tourism.In this study, it is aimed to assess the factors that affect the choice of people and to concatenate the alternatives in terms of domestic touristic tours, overseas tours and domestic cultural tours. In this context, firstly factor primacies are calculated by Analytic Hierarchy Process then the alternatives are concatenated by Fuzzy PROMETHEE method. According to the results it is ascertained that novelty seeking is the most important factor and overseas tours are the preferential alternative.
In the current, highly competitive marketplace, customer demand is a major factor in the product design process. Most firms make an effort to indicate that their products differ from the competitors' products. The purpose of this paper is to understand customers' expectations of and technical requirements for e-stores and to evaluate most popular e-stores in Turkey (i.e., ES1, ES2, ES3). In this study, the authors aim to understand the customer expectations and technical requirements by using quality function deployment (QFD). To prepare the house of quality (HoQ), the authors surveyed 20 experts who are customers who have elite membership (their expenses for these e-stores are more than regular customers and have elite cards) of the three e-stores and academicians. After creating the HoQ, the authors employ fuzzy linear regression to evaluate the relationships between customer expectations and technical requirements and among technical requirements themselves. Finally, the authors use zero-one goal programming (ZOGP) to select the most desirable e-store.
