TOPLAM EKİPMAN ETKİNLİĞİNİN İYİLEŞTİRİLMESİNDE TRIZ KULLANIMI: BİR UYGULAMA

Toplam Ekipman Etkinliği, kullanılan ekipmanların çalışma saatleri içindeki kullanım etkinliğini ölçmeye yarayan bir performans göstergesidir. Bu değer dünya standartlarında % 85 olarak kabul edilmiştir. TRIZ Yöntemi ise problemlerin çözümünde sistematik yaklaşım sağlayan yaratıcı çözümlere sahip olan bir çözüm teorisidir. TRIZ Yöntemi çeşitli patent incelemeleri sonucu ortaya çıkan, 39 mühendislik parametresi ve 40 yaratıcı ilkeyi kapsayan çelişkiler matrisinden oluşmaktadır. Bu çalışmanın ilk aşamasında bir işletmenin deterjan üretim bölümünde TEE verileri bir dönem boyunca toplanarak ortalama TEE değeri bulunmuştur. Bu değer dünya standartları ile karşılaştırılmış olup bulunan TEE değerinin bu standarta yaklaştırılması için TRIZ Yöntemi sistematik bir şekilde uygulanmıştır. TRIZ Yöntemi ile belirlenen öneriler, TEE değerini arttıracak küçük iyileştirmeleri kapsamaktadır.

USE OF TRIZ METHOD IN IMPROVEMENT OF OVERALL EQUIPMENT EFFECTIVENESS

Overall Equipment Effectiveness (OEE) is a performance indicator for measuring effectiveness of the equipments in use during working hours. The minimum value accepted in the world is 85 % for OEE. TRIZ is a creative solution theory providing systematic approaches. It uses a tool called contradiction matrix including 40 creative principles and 39 engineering parameters, which have been appeared as a result of various patent researches. This study was conducted in the production department of an enterprise that produces detergent. At the first stage, average OEE value was calculated based on measurement in one period. Then this value was compared to worldwide standard and some improvements were achieved via TRIZ method.
