New Expansions In The Economic Production Quantity Model Containing Defective Products

Abstract

Klasik üretim miktarı modellerinde temel varsayım üretilen ürünlerin tamamının kusursuz olmasıdır. Ancak gerçek hayatta bu varsayımın her zaman geçerli olması mümkün değildir. Kusurlu ürünlerin oranının rassal değişken olup, belli bir olasılık dağılımına uyduğu durum için EPQ modelleri incelenmiştir. Literatür incelendiğinde kusurlu ürünlerin tarama hızı, üretim hızına eşit kabul edildiği görülmektedir. Bu çalışmada tarama hızının üretim hızından küçük olması durumu altında bir model geliştirilmiştir. Ayrıca kusurlu ürün oranı rassal değişken olup normal dağılıma ve tekdüze dağılıma uyduğu varsayımı ile örnek bir problem çözümü yapılmıştır.

New Expansions In The Economic Production Quantity Model Containing Defective Products

Abstract

The basic assumption in classical production quantity models is that all of the products produced are free of defect. But in real life, this assumption is not always valid. EPQ models were examined for the situation where the proportion of defective products is a random variable and fits a certain probability distribution. When the literature reviewed, it is seen that the scanning speed of defective products is accepted as equal to the production rate. In this study, a model was developed under the condition that the scanning speed is smaller than the production rate. In addition, a sample problem solution was made with the assumption that the defective product ratio is random variable and corresponds to the normal distribution and uniform distribution.
