Abstract
Standardize
edilmiş ürünlerin üretiminde yaygın olarak kullanılan montaj hatları önemli bir
akış tipi üretim şeklidir. Bu hatların dengelenme problemleri üretim ve kaynak
yatırımı maliyetlerinin minimizasyonu açısından büyük önem arz etmektedir.
NP-zor bir yapıya sahip olan probleme endüstriyel ortamlarda yaygın olarak
karşılaşılmasına karşın makul süreler içerisinde kesin çözüm yöntemleri ile
çözümü mümkün olmayabilmektedir. Bu çalışmada yenilenebilir kaynak yatırımı
maliyetini de dikkate alan çok işçili montaj hattı dengeleme problemine yönelik
yeni bir algoritma sunulmuştur. Önerilen algoritmada tamsayılı doğrusal
programlama ile çözülecek olan alt problemler tavlama benzetimi yöntemi ile
belirlenmiştir. Literatürde montaj hattı dengeleme problemlerinde sıklıkla
tercih edilen rassal sayılar dizisi kullanılarak görevlerin hangi önceliklerle
atanacağı belirlenmiştir. Tavlama benzetimi ve tamsayılı doğrusal
programlamanın birlikte kullanımına dayanan algoritmanın etkinliği test
problemleri üzerinde ölçülmüştür. Tavlama benzetimi sezgiseli C# programlama
dilinde kodlanmış ve oluşturulan her bir alt problemin tamsayılı doğrusal
programlama modeli CPLEX 10.2 çözücü kullanılarak 3.2 GHZ /4 GB Ram’a sahip
bilgisayarda koşturulmuştur. Tavlama benzetiminde aynı alt problemler
oluşturulması durumunda hafızada kaydedilen çözüm ve atamalar kullanmıştır.
Bunun temel nedeni matematiksel model ile çözülen alt problemlerde aynı modelin
oluşturulması durumunda elde edilecek sonuçlara daha önceden ulaşılmış
olmasıdır. Bu sayede algoritmanın daha hızlı bir şekilde çalışması
gerçekleştirilmiş olup, çözülen ve tekrarlanan matematiksel model sayıları
özetlenerek sunulmuştur. Geliştirilen
algoritmanın orta ve büyük boyutlu problem örneklerinde kabul edilebilir
kalitede çözümler üretebildiği gözlemlenmiştir. Montaj hattı problemlerine
ilişkin literatürde bulunan çalışmalar dikkate alındığında, ilgili problem
üzerindeki çalışmaların eksikliğine vurgu yapılmıştır.
