An application of quality function deployment for assessing the service quality performance of enterprises

Bu çalışmada, testere üreticisi bir işletmenin, müşterileri tarafından algılanan hizmet kalite performansını ölçmek ve kritik hizmet kalite karakteristiklerini tanımlamak amacıyla Kalite Fonksiyon Göçerimi (KFG) tekniği kullanılmıştır. Çalışma kapsamında, testere makinesini kullanan müşterilerin istek ve beklentilerinin tespit etmek ve işletmenin müşterilerine sunduğu kalite performansını ölçmek üzere bir anket çalışması yapılmıştır. Elde edilen verilere dayanarak Kalite Evi oluşturulmuştur. Çalışmanın sonuç ve değerlendirme kısmında, incelenen işletme için tespit edilen kritik hizmet kalite karakteristiklerine ve hizmet kalite performansına yer verilmiştir.  In this study, a Quality Function Deployment technique is used to define the perceived customer quality performance and determine critical service quality characteristics in a saw production enterprise. Within the framework of the study, a questionnaire is used to determine the requirements and expectations of the costumers using the saw machine and measure the quality performance of the enterprise. Based on the collected data, a House of Quality is built. At the evaluation and conclusion section of the study, the defined critical service quality characteristics and service quality performance of the considered enterprise are presented.&nbsp

Fuzzy analytic network process based multi criteria decision making methodology for a family automobile purchasing decision

Nowadays, in parallel with the advancing technology, automobiles that have substantially advanced technological properties are being manufactured. Intended uses of the automobiles have been changing in our days in contrast to 1960s when automobiles were only used for transportation. Consumers, in our day and age, expect profoundly different properties from an automobile. In this context, more than one criterion become effective on making decision on purchasing an automobile that has the required properties. In such a kind of decision problem, making use of Multi Criteria Decision Making (MCDM) methods will ease the solution of the problem and will enable the decision makers to make right decisions. In this study, fuzzy Analytic Network Process (ANP) method, one of the MCDM methods, is used in automobile purchasing decision making. After determining decision criteria and alternatives, network structure of the automobile selection decision problem is formed, and by using fuzzy ANP method, the best one is selected among three alternative automobiles that are in the same segment and are very approximate to each other in terms of their properties and prices

A Combined Fuzzy-AHP and Fuzzy-GRA Methodology for Hydrogen Energy Storage Method Selection in Turkey

In this paper, we aim to select the most appropriate Hydrogen Energy Storage (HES) method for Turkey from among the alternatives of tank, metal hydride and chemical storage, which are determined based on expert opinions and literature review. Thus, we propose a Buckley extension based fuzzy Analytical Hierarchical Process (Fuzzy-AHP) and linear normalization based fuzzy Grey Relational Analysis (Fuzzy-GRA) combined Multi Criteria Decision Making (MCDM) methodology. This combined approach can be applied to a complex decision process, which often makes sense with subjective data or vague information; and used to solve to solve HES selection problem with different defuzzification methods. The proposed approach is unique both in the HES literature and the MCDM literature

The Complex Genetic Landscape of Hereditary Ataxias in Turkey and Implications in Clinical Practice

Background The genetic and epidemiological features of hereditary ataxias have been reported in several populations; however, Turkey is still unexplored. Due to high consanguinity, recessive ataxias are more common in Turkey than in Western European populations
