Çekme sistemi, malzeme hareketinin bir
sinyal aracılığı ile tetiklendiği üretim yaklaşımıdır. Çekme sistemi genelde
kanban sistemi ile aynı anlamda kullanılmasına rağmen bazı üretim ortamlarında
kanban sisteminin iyi çalışmadığı görülmüş ve kanbana alternatif olan CONWIP ve
POLCA gibi çekme sistemleri geliştirilmiştir. Literatürdeki farklı çekme
sistemlerinden dolayı üretim ortamına ve pazar şartlarına uygun çekme
sisteminin seçilmesi etkili üretim sistemleri geliştirilmesinde önemli bir rol
oynamaktadır. Bu çalışmada kanbana alternatif olarak önerilen CONWIP ve POLCA
çekme sistemleri incelenmiş ve karşılaştırılmalı bir değerlendirme sunulmuştur.
Bu değerlendirmenin sonucu olarak ta uygun çekme sisteminin seçilmesinde
yardımcı olabilecek bir karar destek sistemi geliştirilmiştir. Bu karar destek
sistemi bulanık mantık teorisine dayalı olarak çalışmaktadır. Deneysel sonuçlar
karar destek sisteminin farklı girdiler için iyi sonuçlar üretebildiğini
göstermiştir.
