Çekme sistemleri için karşılaştırmalı bir analiz ve bir karar destek sistemi önerisi

Abstract

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.
