Barrier analysis of solar PV energy development in the context of Iran using fuzzy AHP-TOPSIS method

The design of structures using advanced composite materials such as fiber metal laminate requires an in-depth understanding of their deformation behavior and response to the discontinuities in the structures. In the present study, a GLARE kind of fiber metal laminate in 2/1 configuration was fabricated in the form of conical frustum. Three cut-outs of two different shapes such as circular and square were intentionally made at the center of the frustum at an angular distance of 120 . The quasi-static compression test was conducted to determine the crashworthiness characteristics of laminate frustums with cut-out and the results were compared with perfect frustum. The study showed that the laminate with cut-out undergone for inward buckling near the discontinuities. Apart from that, the delamination and outward buckling were noted in the edges of the cut-outs. The energy absorption of laminate frustum with circular cut-outs was observed to be better than square cut-outs. The performance of laminate frustums with cut-outs was ranked using Technique for Order Preference by Similarity to an Ideal Solution technique. A finite element analysis was carried out to simulate the deformation behavior of laminate frustum with cut-outs and the numerical results of deformation mode closely represented the experimental results.

“…where: Step 2: Compute fuzzy weights using geometric mean method The fuzzy mean geometric value of the ith criterion against each criterion was determined using the geometric mean method, computing the fuzzy triangular vector r i Equation (3). The relative fuzzy criteria weight of the ith criterion is represented as a TFN and computed applying Equation ( 4) [64][65][66]82].…”

The construction industry is one of the most significant consumers of environmental resources worldwide. Faced with the need to produce new buildings, but without further burdening the environment, attempts to improve social, economic, and environmental indicators have turned attention to building construction in recent decades. The objective of this research is to develop a novel framework to assess the most sustainable choice of materials applied to the construction of low-income buildings, according to the three pillars of the Triple Bottom Line (TBL). A BIM-LCSA-FAHP-based model was proposed with the creation of nine different scenarios, where the materials of the structure (precast concrete, cast-in-place concrete, and structural masonry), painting (PVA water-based and acrylic), and roofing (ceramic and fiber cement tiles) varied. The proposed procedure consists of the elaboration of a 3D Building Information Modeling (BIM) model, for which the parameters described above were evaluated according to the Life Cycle Sustainability Assessment (LCSA)-TBL-based criteria, divided into ten sub-criteria, that includes: (1) environmental (acidification, eutrophication, global warming, ozone depletion, smog formation, primary energy, non-renewable energy, and mass total), (2) economic (construction cost) and (3) socio-political issues (community impact). Finally, the Fuzzy Analytical Hierarchy Process (AHP) was used as a multi-criteria decision-making technique that helps in aggregating and classifying the impacts of each scenario in a sustainability index (SI). Regarding the best option for low-income construction, the results indicated that precast concrete when combined with acrylic paint and fiber cement tiles (scenario 3) proved to be the most advantageous and achieved first place in the sustainability index (SI) developed in this work. This methodology is replicable for different construction typologies and several categories of materials, making it a robust decision-aiding tool for engineers, architects, and decision makers.

İlk resmi COVID-19 vakasının Mart 2020'de tespitinden sonra pandeminin etkilerini en aza indirgemek için Türkiye'de “Ekonomik İstikrar Kalkanı” adı verilen yeni paket hayata geçirilmiştir. Tüm sektörlerde olduğu gibi gayrimenkul sektöründe de salgın çeşitli değişikliklere sebep olmuştur. Salgın döneminde uzun süre evlerde kalan vatandaşların ev alırken talepleri de değişikliğe uğramıştır. Bu çalışma, gayrimenkul sektöründe konut satın alma kriterleri için seçim kriterlerinin önemini araştırmayı ve Çok Kriterli Karar Verme (MCDM) yaklaşımıyla en uygun evi belirlemeyi amaçlamaktadır. Bu çalışmada, Bulanık Analitik Hiyerarşi Süreci (BAHS) ve Multi-Attribute Ideal Real Comparative Analysis (BMAIRCA) yöntemleri bir arada kullanılarak konut satın alma değerlendirme kriterleri ve aday konutlar değerlendirilmektedir. Bu değerlendirme yapılırken, kriterlerin ağırlıklarını belirlemek için Konya'da yaşayan beş aileden veri toplanarak ikili karşılaştırmalar ile bulanık ortam altında kriter ağırlıkları elde edilmiştir. Daha sonra, aday konutları ailelerin görüşlerine göre sıralamak için BMAIRCA yöntemi kullanılmıştır. Araştırma sonucunda krediye uygunluk kriterinin en önemli kriter olduğu tespit edilmiştir. Örnek vaka çalışması için, bulanık TOPSIS ve bulanık VIKOR'un konut satın alma performansı üzerine karşılaştırma analizi gerçekleştirilmiştir. Örnek vaka çalışması için karşılaştırma analizimiz, üç bulanık yöntemin aynı sıralamalara ulaştığını göstermektedir
