Abstract (2. Language): 
As it is known, Fuzzy Set Theory mainly deals with the vague in human's mind, perceptions and numerilizing this vague. I mean, it provides precise and consistent decisions for people by the help of imprecise and vague information, in other words, Fuzzy Set Theory deals with modelling and thinking and decision engines by using Fuzzy Logic. In this study that logic of Fuzzy Set Theory is used to realize a rational facility layout. Adding to these, qualitative and quantitative based data are converted into linguistic variable and membership functions by using fuzzy set approach, from these values truth-value matrices for each facility and location is received, later on Integrated truth-value matrix, which will provide our real goal, is found by multiplying idea of intense relationship, flow and closeness criteria with those two truth-value matrices which takes qualitative and quantitative data between facilities as a base. This matrix is weighted according to the process volume of its facilities, the average demand ratios are sequenced from smaller to greater locationally and the sequenced layouts of these facilities that correspond to those demand ratios are obtained.
Abstract (Original Language): 
Bilindiği gibi bulanık küme teorisi; esas olarak insan düşünce ve algılarındaki belirsizlikle ve bu belirsizliğin sayısallaştırılması ile ilgilenmektedir. Yani tam ve kesin olmayan bilgiler ışığında insanların tutarlı ve doğru kararlar vermelerini sağlayan, diğer bir deyişle bulanık mantık yardımıyla düşünme ve karar verme mekanizmalarının modellenmesi ile ilgilenmektedir. Bu çalışmada rasyonel bir tesis düzenlemesini gerçekleştirebilmek için bulanık küme teorisinin bu mantığından yararlanılmıştır. Bu çalışmada bulanık küme yaklaşımından yararlanarak kalitatif ve kantitatif bazlı veriler, dilsel değişken ve üyelik fonksiyonlarına dönüştürülmüş, elde edilen bu değerlerden her tesis ve lokasyon için gerçek değer matrisleri elde edilmiş, daha sonra tesisler arasındaki kalitatif ve kantitatif verileri esas alan bu iki gerçek değer matrisi "yoğun ilişki, akış ve yakınlık kriterleri"nin verdiği düşünce ile, çarpılarak esas amacı sağlayacak "birleştirilmiş gerçek değer matrisi" elde edilmiştir. Bu matris; tesislerin işlem hacimlerine göre ağırlıklandırılarak, yerleşim (lokasyonel) olarak ortalama talep oranları küçükten büyüğe doğru sıralanmış ve bu talep oranlarına karşılık gelen mevcut tesislerin sıralı düzenlemesi elde edilmiştir.
