Taguchi metodu: Bir uygulama

Taguchi metodu, düşük maliyetli ve yüksek kaliteli ürün üretmede önemli bir metottur. 1960 'lı yıllardan beri Japonya'da ve 1980'li yıllardan beri de ABD endüstrisinde başarı ile uygulanmaktadır. Taguchi metodu, bütün ürünlerin istenilen hedef değerde üretilmesi gerektiğine işaret etmekte, hedeften sapmayla birlikte kalite kayıplarının da başladığını ve bu kaybın giderilmesinin ancak iyi bir tasarım ile sağlanabileceğini belirtmektedir. Taguchi, bunu sağlamak için de temeli istatistiksel deney tasarımına dayanan bir çok tekniği kullanmıştır. Sağlam tasarım diye adlandırdığı çalışmaları ile birlikte ortogonal dizi, doğrusal grafikler ve sinyal/gürültü oranı gibi bazı kavramların kalite literatürüne girmesini sağlamıştır.Bu makalede, Taguchi metoduna genel bir bakış verilmeye çalışılmış, metodun sistematiği açıklanmıştır.

Taguchi method: An application

Taguchi method is an important method of producing products in low cost and high quality. This method has been applied in Japan since 1960's and in USA since 1980's. Taguchi method points out that, all products should be produced at the target values. A diversion from the target brings out quality losses. These losses can be eliminated by a robust design. In order to do that, Taguchi used a number of techniques based on the statistical experimental design. Taguchi's works on robust design provided concepts such as orthogonal array, lineer graphs, signal/noise ratio to become part of quality literature. In this article, a general overview of Taguchi method is given and its systematic is explained.
