MALİYET TABANLI STOKASTİK MONTAJ HATTI DENGELEME PROBLEMİ

İşletmelerde ekonomik çalışma gereğinin büyük önem taşıdığı günümüzde, kaynakların etkin olarak kullanılıp değerlendirilmesi oldukça önemli bir konudur. Bu nedenle montaj hatlarında maliyetlerin azaltılması ve iş gücü gibi kaynaklardan verimli şekilde faydalanmak zorunluk hale gelmiştir. Bu makalede Maliyet Tabanlı Stokastik Montaj Hattı dengeleme problemi ilk kez ele alınmış ve bu amaçla bir şans kısıtlı matematiksel model önerilmiştir. Önerilen model, IBM ILOG CPLEX 12.4 yazılımı yardımıyla küçük ve orta boyutlu problemler için çözülmüştür. Elde edilen en iyi çözümler, aynı problemin zaman tabanlı yaklaşımla elde edilen en iyi çözümleri ile istasyon sayısı ve toplam işgücü maliyeti açısından karşılaştırılmıştır. Maliyet tabanlı modelin amaç fonksiyonu, istasyon sayısının en aza indirilmesi olmamasına rağmen, zaman tabanlı modele karşın çözülen 79 problemin tümünde, aynı sayıda istasyon ve 64 tanesinde daha düşük maliyetler elde edilmiştir.
