Efficient facility layout planning is essential for optimizing workflow, reducing material handling costs, and enhancing production efficiency. In flange manufacturing, ineffective layouts lead to increased transportation costs and production inefficiencies. Applying systematic layout optimization strategies is crucial for maintaining competitiveness and cost-effectiveness. This study examines the optimization of facility layouts using CRAFT (Computerized Relative Allocation of Facilities Technique) and CORELAP (Computerized Relationship Layout Planning) algorithms. These methods are designed to minimize material handling costs and improve spatial organization. The study finds that CRAFT is more suitable for modifying existing layouts, while CORELAP is ideal for new facility designs. Implementation results show that CORELAP reduced material handling costs by 7%, from 845 to 787, while CRAFT achieved a 12% reduction, lowering costs to 747. These improvements enhance operational efficiency and long-term cost savings. Instead of a complete restructuring, both algorithms focus on incremental layout enhancements, preventing major production disruptions. Simulation results confirm that CRAFT increases efficiency with minimal layout modifications, reducing material handling distances and accelerating production. Given its cost-effective and practical application, particularly for small and medium-sized enterprises, CRAFT was deemed the preferred approach for this study.

Verimli tesis yerleşim planlaması, iş akışını optimize etmek, malzeme taşıma maliyetlerini azaltmak ve üretim verimliliğini artırmak için gereklidir. Flanş üretiminde, etkin olmayan yerleşim planları nakliye maliyetlerinin artmasına ve üretim verimsizliklerine yol açar. Sistematik yerleşim optimizasyonu stratejilerinin uygulanması, rekabet gücünün ve maliyet etkinliğinin korunması için çok önemlidir. Bu çalışma, CRAFT (Tesislerin Bilgisayarlı Göreceli Tahsis Tekniği) ve CORELAP (Bilgisayarlı İlişki Düzen Planlaması) algoritmalarını kullanarak tesis yerleşimlerinin optimizasyonunu incelemektedir. Bu yöntemler, malzeme taşıma maliyetlerini en aza indirmek ve mekânsal organizasyonu iyileştirmek için tasarlanmıştır. Çalışma, CRAFT'ın mevcut yerleşim planlarının değiştirilmesi için daha uygun olduğunu, CORELAP'ın ise yeni tesis tasarımları için ideal olduğunu ortaya koymaktadır. Uygulama sonuçları, CORELAP'in malzeme taşıma maliyetlerini %7 azaltarak 845'ten 787'ye düşürdüğünü, CRAFT'ın ise %12'lik bir azalma sağlayarak maliyetleri 747'ye indirdiğini göstermektedir. Bu iyileştirmeler operasyonel verimliliği ve uzun vadeli maliyet tasarruflarını artırmaktadır. Her iki algoritma da komple bir yeniden yapılandırma yerine kademeli yerleşim iyileştirmelerine odaklanarak büyük üretim kesintilerini önlemektedir. Simülasyon sonuçları, CRAFT'ın minimum yerleşim planı değişiklikleriyle verimliliği artırdığını, malzeme taşıma mesafelerini azalttığını ve üretimi hızlandırdığını doğrulamaktadır. Özellikle küçük ve orta ölçekli işletmeler için uygun maliyetli ve pratik uygulaması göz önüne alındığında, CRAFT bu çalışma için tercih edilen yaklaşım olarak kabul edilmiştir.
