While competition has become worldwide, manufacturing firms need to implement powerful productivity improvement methods. It is known that “overall equipment effectiveness” is the key metric to measure the performance of individual equipment. Different production subsystems (e.g.: serial, parallel, assembly line) and different aims (e.g.: decreasing the speed loses, increasing production rate, identifying bottleneck operation) of manufacturing plants, required different metrics for productivity which measure the effectiveness of whole system. So, in the literature, diversity of techniques are presented as “overall factory effectiveness”, “overall throughput effectiveness”, “overall asset effectiveness”, “overall equipment effectiveness of a manufacturing line” and so on. This study proposed a method to calculate overall effectiveness in serial subsystem which processes multiple orders in each batch. In the examined system, after a couple of continuous operation on different machines, there is a final quality control for each order of batch. Different processing time of utilizing machines cause different unit processing rates. Equipment down times is also considered in the examined study. 

 

 

Rekabet dünya genelinde gerçekleşirken, imalat firmaları, güçlü verimlilik geliştirme yöntemlerini uygulamak zorundalardır. "Toplam ekipman etkinliği" yönteminin, tek tek ekipmanların performansını ölçmek için kullanılan temel ölçüt olduğu bilinmektedir. Üretim tesislerinin farklı üretim alt sistemleri (örneğin: seri, paralel, montaj hattı) ve farklı amaçları (örneğin: hız kaybını azaltmak, üretim hızını artırmak, darboğaz operasyonunu tanımlamak), bütün sistemin etkililiğini ölçen farklı verimlilik metriklerine ihtiyacı ortaya çıkarmıştır. Dolayısıyla, literatürde, "toplam fabrika etkinliği", "toplam çıktı etkinliği", "aktiflerin toplam etkinliği", "üretim hattının toplam ekipman etkinliği" vb. gibi çeşitli teknikler önerilmiştir. Bu çalışmada ise, her partide çoklu siparişleri işleyen seri alt sistem dâhilinde toplam etkinliği hesaplamak için bir yöntem önerilmiştir. İncelenen sistemde, farklı makinelerdeki ardıl operasyonlardan sonra, her yığındaki sipariş için nihai kalite kontrolü yapılır. Makinelerin farklı işleme süreleri, farklı birim işleme hızlarına neden olur. İncelenen çalışmada duruş süreleri de dikkate alınmıştır.
