Abstract:

 


Process planning, scheduling and due date
assignment are three important manufacturing functions in production system in
which process planning is input to scheduling processes. Because of rigid
process plans, alternative plans are not used that may affect global
performance improvement in a bad way. Besides, scheduling without considering process
plans causes unbalanced machine loadings and leads to several bottlenecks. In
the literature, there are numerous works on process planning and scheduling and
works on scheduling with due date assignment. These three functions are not
integrated much. According to literature,
due dates are assigned without considering weights of the customer. In this
study, these three functions are integrated and due dates are given according
to the importance of the customers. Eight shop floors are studied. Different
levels of integration of these three functions are tested and compared with
each other. Two search techniques used which are genetic search and random
search and results are compared with ordinary solutions. As the level of
integration increased solutions became better and search techniques gave a better
result than ordinary solutions and the genetic search outperformed random
search.

Proses planlama, çizelgeleme ve teslim tarihi belirleme üç
önemli imalat fonksiyonudur. Literatüre göre proses planlama ve çizelgelemenin
entegrasyonu ve teslim tarihi belirlemeli çizelgeleme üzerine çok sayıda
çalışma vardır. Fakat bu üç fonksiyonun entegre edildiği çalışmalar azdır.
Literatüre göre teslim tarihleri müşteri ağırlıklarını hesaba katmadan verilmektedir.
Bu çalışmada üç fonksiyon entegre edilmiş ve teslim tarihleri müşteri önemi
hesaba katılarak verilmiştir. Sekiz atölye çalışılmıştır. Bu üç fonksiyonun
farklı entegrasyon seviyeleri test edilmiş, birbirleriyle karşılaştırılmıştır.
Genetik arama ve rassal aramadan oluşan iki arama tekniği kullanılmış ve
sonuçları sıradan çözümlerle karşılaştırılmıştır. Entegrasyon seviyesi arttıkça
sonuçlar daha iyi olmuş, arama teknikleri sıradan çözümlere göre daha iyi
sonuçlar vermiş ve genetik arama rassal aramadan üstün çıkmıştır.
