Abstract

Transfer
line is a serial arrangement of machines where buffers are used to separate two
consecutive machines. This special type of production systems have high
production volumes.  In the design and
operation of transfer lines, throughput analysis is essential. Considering the
transient state of the systems, this paper presents theoretical analysis for
throughput rate of transfer lines. For the short transfer lines, having a
unique machine and two machines, we derive throughput rate, expected value and
variance functions. We use these functions in performance evaluation of
production systems. Besides, these theoretical analyses can be used while
analyzing longer and more complex transfer lines which can easily be decomposed
into smaller sub-systems.

Transfer Hatlarında Geçici Durum Çıktı Analizi: Analitik Metod Kullanımı

Abstract

Transfer hatları üretimde makinelerin
seri olarak düzenlendiği ve iki ardışık makinenin ara tamponlarla ayrıldığı
sistemlerdir. Bir üretim sistemi olan transfer hatlarının yüksek üretim hacmine
sahiptir. Transfer hatlarının, tasarım ve operasyonlarında çıktı analizi önemli
bir yere sahiptir. Bu çalışma, transfer hatlarında çıktı analizi üzerine teorik
sonuçlar sunmaktadır. Tek makineli ve iki makineli transfer hatlarının çıktı
dağılım, beklenen değer ve sapma fonksiyonları oluşturulacaktır. Elde edilen
fonksiyonlar, bu üretim sistemlerinin performans değerlendirilmesinde
kullanılacaktır. Bunun yanında, küçük sistemlere ayrıştırılabilecek olan daha
uzun ve karmaşık transfer hatlarının analizinde de bu derivasyonlar
kullanılabilir.
