Abstract

Malzeme İhtiyaç Planlama MİP sistemi, stok maliyetlerini azaltırken verimliliği ve müşteri memnuniyetini artırmayıhedefleyen bir üretim yönetim sistemidir. Son yıllarda, Türkiye’de özellikle imalat sanayiinde bir çok firma bu sistemi kullanmaya başlamışveya kullanmayıplanlamaktadır. Her yeni sistemde olduğu gibi MİP sistemi, gerçek üretim sistemlerinin doğasında barındırdıklarıkarmaşıklığın ve belirsizliğin etkisiyle, başlangıç aşamasında pek çok güçlük içerir.Bu çalışmada, güneşenerjisi ve su ısıtma sistemleri imal eden bir işletmede, işlem sürelerindeki belirsizliğin Bulanık Küme Teorisi ile tanımlandığıdurumda MİP sisteminin uygulanmasıincelenmektedir.

Material Requirements Planning MRP system is a production management system which

Abstract

aims for increase in productivity and customer pleasure as decreasing in inventory costs. Recent years, in Turkey, most of firms especially in manufacturing industry started or planned to use this system. MRP system as every new system, with the effect of complexity and uncertainty inherent in real production systems, contains lots of difficulties at the beginning phase. In this study, uncertainty in processing times are dealt with Fuzzy Sets Theory, and an application of material requirements planning system in a firm manufacturing solar energy and water heating systems is presented

Keywords
