SIRA BAĞIMLI HAZIRLIK OPERASYONLARI İÇİN TEK EKİPLİ PARALEL MAKİNALARDA ÇİZELGELEME PROBLEMİNE KARMA YAKLAŞIM

Bu çalışmada; paralel makinelerde hazırlık süresinin sıra bağımlı olduğu, bir başka ifadeyle işin hazırlıksüresinin bir önceki işe bağlı olarak farklılık gösterdiği ve hazırlık operasyonlarının bir ekip tarafındangerçekleştirildiği, iş çizelgeleme probleminin tamamlanma süresini en küçükleyecek sezgisel bir yaklaşımsunulmuştur. Problem çözümü için genetik algoritma ve tabu arama yaklaşımlarını birlikte kullanan bir yaklaşımönerilmiştir. İlk olarak, genetik algoritma ile problemin başlangıç çözümü elde edilmiş ve sonrasında daha iyiçözümler elde etmek için tabu arama yöntemi kullanılmıştır. Bu yaklaşımın performansı, rastgele arama yöntemisonuçları ile kıyaslanarak analiz edilmiştir. Sonuç olarak, önerilen yaklaşımın, P2,S|STsd|Cmax problemindeetkin olduğu görülmüştür.
