Ofis Mekanlarında Döşeme Kaplama Malzemesinin Bulanık Kümeler Kullanılarak Seçimi

Öz

Döşeme kaplama malzemeleri; döşeme katmanlarını koruma, işlevsel ve estetik olma, kullanıcı güvenliği ve konforunu sağlama gibi amaçlarla yapılmaktadır. Bu yüzden mekanın ve kullanıcı ihtiyacının iyi saptanmasının yanında malzemenin yatırım maliyeti, hizmet ömrü, dayanıklılığı, işletme maliyeti, konforu, çevresel etkisi karar verme safhasında etkili etmenlerdir. Farklı özelliklere sahip kaplama malzemeleri bu seçim etmenleri kapsamında değerlendirildiklerinde farklı avantaj ve dezavantajlara sahip olabilmektedirler. Döşeme kaplama malzemesi seçiminde, malzemelerin bu özelliklerinin bir arada düşünülmesi ve alternatifler arasında en uygun kararın verilmesi büyük önem taşımaktadır. Karmaşık karar süreçlerini gerektiren bu işlemin daha sistematik ve gerçekçi bir düzlemde yapılması daha sağlıklı olacaktır. Bu nedenle “doğru (1)” ve “yanlış (0) olarak keskin değerlendirmeler yapan klasik mantıklı bilgisayar seçim sisteminin aksine tıpkı insan beyni gibi birçok kriteri birlikte ele alarak değerlendirme yapan ve bilgideki eksikliği gözetebilen bir yaklaşım olan bulanık mantık yöntemi seçilmiştir. Çalışmada; ofis mekanlarındaki döşeme kaplaması seçiminde karar kriterlerinin bulanık mantık yaklaşımıyla değerlendirilerek, döşeme kaplaması seçiminde daha gerçekçi bir karar süreci oluşturmayı amaçlanmıştır. Döşeme kaplama malzemeleri için belirlenen seçim kriterleri (yatırım maliyeti, hizmet ömrü, işletme maliyeti ve çevresel etkisi) ve ofis döşemelerinde yaygın olarak kullanılan malzemelere (ahşap, halı, PVC ve seramik) bulanık kümelerle üyelik fonksiyonları tanımlanmış ve oluşturulan kurallar doğrultusunda model tamamlanmıştır. Daha sonra seçim kriterleri üzerinden dengeli, işletme maliyeti odaklı ve çevresel etki odaklı olmak üzere 3 farklı senaryo oluşturulmuş ve bu senaryolar Matlab programında oluşturulan model üzerinden değerlendirilmiştir. Yapılan değerlendirmeler sonucu ahşap, PVC, halı ve seramik kaplama malzemeleri arasından ahşabın tüm senaryolarda ağırlıklı olarak en uygun tercih olduğu görülmüştür.

Selection Of Flooring Material In Office Spaces Using Fuzzy Sets

Öz

Floor covering materials are made for the purposes of protecting the floor layers, being functional and aesthetic, ensuring user safety and comfort. Therefore, in addition to determining the space and user needs well, the investment cost of the material, service life, durability, operating cost, comfort and environmental impact are effective factors in the decision-making phase. When covering materials with different properties are evaluated within the scope of these selection factors, they may have different advantages and disadvantages. In the selection of floor covering materials, it has great importance to consider these properties of the materials together and to make the most appropriate decision among the alternatives. It would be healthier to perform this process, which requires complex decision processes, on a more systematic and realistic level. Therefore, unlike the classical logical computer selection system that makes sharp evaluations as “correct (1)” and “incorrect (0), the fuzzy logic method, which is an approach that evaluates by considering many criteria together just like the human brain and can consider the deficiency in information, was chosen. In the study; it was aimed to create a more realistic decision process in the selection of floor coverings by evaluating the decision criteria in the selection of floor coverings in office spaces with the fuzzy logic approach. The selection criteria for floor covering materials (investment cost, service life, operating cost and environmental impact) and membership functions for materials commonly used in office flooring (wood, carpet, PVC and ceramics) were defined with fuzzy sets and the model was completed in line with the established rules. Then, 3 different scenarios were created based on the selection criteria, namely balanced, operating cost focused and environmental impact focused, and these scenarios were evaluated using the model created in the Matlab program. As a result of the evaluations, it was seen that wood was the most suitable choice among wood, PVC, carpet and ceramic flooring materials in all scenarios.
