“…Gabus ve Fontela [55] tarafından geliştirilen DEMATEL metodunu ilk olarak bulanık mantık teorisi ile genişleterek Lin ve Wu [56] kullanmıştır. Bu yöntem matris veya yönlü grafikler ile karmaşık nedensel ilişkilerin yapısını görselleştirmek için yararlıdır.…”

:Konut memnuniyeti araştırmalarında genellikle anket uygulaması ve sonuçlarının değerlendirilmesine odaklanan çalışmaların varlığı dikkat çekmektedir. Ancak ankete dayalı bu çalışmaların mekânsal karşılıklarına yönelik modelleme eksikliği nedeni ile planlamada karar verme süreçlerine yönlendirici bir katkı sağlanamamaktadır. Bu çalışmada bulanık çok kriterli karar verme yöntemleri (Bulanık DEMATEL+Bulanık TOPSIS) kullanılarak, iki farklı TOKİ toplu konut bölgesinde konut memnuniyetinin değerlendirilmesine yönelik bir model oluşturulmuştur. Toplu konut bölgeleri arasındaki memnuniyeti etkileyen faktörler ve mekânsal karşılıklarına yönelik bulanık bir değerlendirme gerçekleştirilmiştir. Elde edilen sonuçlar ile her iki toplu konut bölgesi için geoistatistik analiz tabanlı ve Coğrafi Bilgi Sistemi (CBS) destekli karşılaştırılabilir konut memnuniyeti haritası oluşturulmuştur. Plan, tipoloji ve tasarım yaklaşımları aynı olan iki TOKİ bölgesinden Yenidoğan TOKİ bölgesinde konutlardan memnuniyet oranının %60 gibi yüksek bir oranda olduğu, buna karşılık İldem TOKİ bölgesinde ise memnuniyetin son derece düşük olduğu belirlenmiştir. Çalışma sonucunda konut memnuniyet düzeyindeki farklılığın temelde alanın yer seçimi üzerine odaklandığı, kent merkezi ile kurulan ilişkinin, ulaşım bağlantılarının güçlü etkenler olduğu gözlemlenmiştir. In housing satisfaction research, studies that focus on the evaluation of surveying and its results draw much attention. However, a guiding contribution cannot be made to the decision-making processes in planning due to the lack of modelling for the spatial provisions of these survey-based studies. This study was conducted using two multi-criteria decision-making methods (Fuzzy DEMATEL+ Fuzzy TOPSIS), and a model was created for the evaluation of housing satisfaction in two different TOKI housing estates. A fuzzy examination was carried out on the factors that affect satisfaction with the housing estates and their spatial provisions. A comparable housing satisfaction map based on a geostatistical analysis and supported with Geographic Information System was created for both housing estates using the obtained results. The planning, typology and design approaches of both TOKI housing estates are the same, but the level of the satisfaction with the houses in the Yenidoğan TOKI housing estate was found to be as high as 60%, while the level of satisfaction with the Ildem TOKI housing estate was found to be extremely low. The study concluded that this difference derived from site selection, and that relationships with the city centre and transportation corridors were determinant factors.

“…With respect to the fact that we require expert's opinions for the use of DEMATEL technique may be vague, we use fuzzy numbers for better handling the numbers. Lin and Wu (Lin & Wu, 2008) presented a model which benefits of DEMATEL technique in fuzzy environment and the following summarize it, Step1: determine decision objectives and form a committee for opinion collecting in problem solving, Step2: determine evaluation measures based on fuzzy nominal scale, We use the fuzzy DEMATEL model proposed by Li (1999) for the study of this paper. Different "influencing" degrees are expressed by five words of "very high, high, low, very low, no influence" and their opposite positive triangular Fuzzy numbers are indicated in Table 3.…”

Organizations with activities of all kinds are influenced by environmental conditions, and external environment is in fact the beginning point of the strategy. Strategic management is an approach resulting from fast changing age and can consider it as a view and a technique for flexible planning to fast changes, and balanced score card is regarded as one of the strong instruments in this zone. Balanced score card can truly plays an important role in all stages of strategic management and the efficiency of this model is considerably regarded in management performance evaluation in different organizations. However, strong instrument such as balance score card is hardly used because of long term dominance of political approaches in the management of Iran media organizations. This paper conceptualizes administrational trend of strategic planning by implementing balanced score card and we draw strategy map and determine performance indexes in a written media organization (Hamshahri Newspaper).

It has been an applied method for various business decision makings, such as group decision making and management decisions [18]. The procedures of building an ANP model is described as below [19]- [20]:…”

Abstract-Stock market is regarded as a highly dynamic and complex environment consisting of opportunities and risks. All participants want to earn profits by adopting their investment strategies. One of the most famous investment strategies is value investing, which attracts both practitioners and researchers' attention all over the world. Empirical studies have consistently found that value stocks outperform the market in the long run, but it often encounters obstacles to implement this strategy in practices. Due to the need of in-depth analysis of financial statements, investors not only need accounting knowledge but also investment expertise. Among previous studies, the accounting-based fundamental analysis (F-score) has been a widely accepted model for value investing. The F-score model proposed nine fundamental signals to measure a firm's financial prospect. However, it is difficult to acquire the implicit knowledge and interactive considerations of senior experts. Thus, the evaluation processes of investment experts cannot be revealed for the others' reference. To improve the limitations, this paper integrates fuzzy set theory and decision methods to propose an innovative model for distinguishing strong financial prospect stocks within high book-to-market (B/M) banking stocks. Our empirical study shows the practicability of our proposed method. It also provides the relative weights and the interdependence of each measurement variables for the value investing strategy.
