(2004)Hata Tütü ve Etkileri Analizi, yüzlerce hata türü için iyileştirme yapılmasının planlanması yerine, sistemin bütünü üzerinde en büyük katkıyı sağlayacak hata türlerini önceliklendiren bir yöntemdir. Ancak yüzlerce hata ... -
Estimating and statistically analyzing the global solar radiation potential over big cities in Turkey
(Multi Science Publ Co LTD, 2007)This study develops empirical models in order to estimate the monthly average daily global solar radiation on a horizontal surface (H). The seven big cities considered in the model have 33.4% of Turkey's population and are ... -
Determination of optimum insulation thicknesses of the external walls and roof (ceiling) for Turkey's different degree-day regions
(Elsevier Sci LTD, 2007)The external walls and roof of a building are the interface between its interior and the outdoor environment. Insulation of the external walls and roof is the most cost-effective way of controlling the outside elements to ... -
Forecasting Residential Consumption of Natural Gas Using Genetic Algorithms
(Sage Publications Inc, 2008)This paper presents an application of genetic algorithms to forecast short-term demand of natural gas in residences. Residential demand is assumed to be a function of time. heating degree-day value, and consumer price ... -
Fuzzy individual and moving range control charts with alpha-cuts
(Ios Press, 2008)In Statistical Process Control (SPC), both variable and attribute control charts are widely used techniques to monitor and evaluate the process with respect to the related quality characteristics. In variable control charts, ... -
Construction of a fuzzy QFD failure matrix using a fuzzy multiple-objective decision model
(Taylor & Francis LTD, 2010)Global competition has forced companies to consider increasing quality and decreasing all costs, including quality costs. When constructing the quality plan for both the incoming raw materials and the manufacturing process, ... -
Modeling and analysis of packing properties through a fuzzy inference system
(Springer, 2010)Packing of manufactured products is important in protecting them from damage during handling and transportation. Several materials and methods are used for packing of products and the optimum level of packing materials ... -
Evaluating the Packing Process in Food Industry Using Fuzzy X ~ and S ~ Control Charts
(Atlantis Press, 2011)The fuzzy set theory addresses the development of concepts and techniques for dealing with uncertainty or impression conditions. If the collected data from a process include vagueness due to human subjectively or measurement ... -
Hybrid approach for Pareto front expansion in heuristics
(Palgrave Macmillan LTD, 2011)Heuristic search can be an effective multi-objective optimization tool; however, the required frequent function evaluations can exhaust computational sources. This paper explores using a hybrid approach with statistical ... -
Evaluating the packing process in food industry using fuzzy and [stilde] control charts
(2011)The fuzzy set theory addresses the development of concepts and techniques for dealing with uncertainty or impression conditions. If the collected data from a process include vagueness due to human subjectively or measurement ... -
An approach to measuring brand loyalty in the Turkish automotive sector
(2011)Türkiye otomotiv sektöründe empirik bir araştırmaya dayanan bu çalışmada, bulanık mantık teorisi ve yapısal eşitlik modeli kullanılarak satın alma düşüncesini etkileyen ve hizmet sağlayıcısının gücünü oluşturan üç gizil ... -
Numerical optimization of a fin-tube gas to liquid heat exchanger
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2012)The influence of plate fin, fin tube and protrusion parameters on heat transfer and pressure drop characteristics of a finned tube gas to liquid heat exchanger is examined in this study. The optimization of plate fin, fin ... -
A bi-objective model for the retail spatial design problem
(Taylor & Francis LTD, 2012)In this article, a model for the design of the block layout of a retail store is presented as a bi-objective optimization problem. The approach consists of placing departments in a racetrack configuration within the store ... -
Retail space design considering revenue and adjacencies using a racetrack aisle network
(Taylor & Francis Inc, 2012)In this article, a model and solution approach for the design of the block layout of a single-story department store is presented. The approach consists of placing departments in a racetrack configuration within the store ... -
A new crossover operator for single machine total weighted tardiness problem with sequence dependent setup times
(2012)The single machine total weighted tardiness problem with sequence dependent setup times is a challenging and heavily studied problem. This problem is NP-hard, so several heuristics have been proposed in the literature so ... -
Kurum imajı analizi: Bir üretim işletmesi örneği
(2012)Özellikle Endüstri Devriminden sonra rekabetçi pazarda öne çıkma çabalarına paralel olarak meydana gelmiş olan imaj kavramı, günümüzde salt görsellikten ibaret bir kavram olmaktan çıkmıştır. Güvenilirlik, kalite, istikrarlılık ... -
