Bina Betonunun Karışım Oranı için Kaba-AHP ve MOORA Tabanlı Taguchi Optimizasyonu

Öz

İnşaat sektöründe inşaat betonu üretiminde kullanılan malzemeler ve bunların karışım oranları beton üreticileri için önemli bir karar verme ve optimizasyon problemidir. Yüksek dayanımlı ve fonksiyonel beton karışımı elde etmek için kullanılan malzemelerin miktarları (karışım oranları) her müşteri için ayrı ayrı belirlenen performans kriterlerini olumlu veya olumsuz etkileyebilir. Ayrıca her bir performans kriterinin beton üzerindeki etkisi ve önemi birbirinden farklı olabilir. Bu makale, müşteri taleplerine göre karar verilen performans kriterlerinin önem düzeylerini ve ağırlıklarını belirlemek için Kaba-AHP yaklaşımını ve müşteri talebi için betonun optimum karışım oranını hesaplamak için MOORA tabanlı Taguchi yaklaşımını önermektedir. Tüm deneysel tasarımların yapılmasından ziyade deney süresini ve maliyetini en aza indirecek deney tasarımının en iyi şekilde belirlenmesi amaçlanmaktadır.

Rough-AHP and MOORA-based Taguchi Optimization for Mixture Proportion of Building Concrete

Öz

In the construction industry, materials that are used for producing construction concrete and their mixture proportions are an important decision-making and optimization problem for concrete manufacturers. Amounts (mixture proportions) of the materials, which are used in order to obtain a mixture of high strength and functional concrete, can positively or negatively affect performance criteria which are individually determined for each customer. Furthermore, the effect and significance of each performance criterion on the concrete may differ from each other. This paper proposes the Rough-AHP approach to determine the significance levels and weights of the performance criteria decided according to the customer demands and the MOORA-based Taguchi approach to calculate the optimal mixture proportion of the concrete for the customer demand. It is aimed to determine the best design of the experiment to minimize the experiment duration and cost rather than to perform all experimental designs.
