A Value Engineering Applicaton for Cost and Quality Improvement in Domestic Type Gas Hobs

Abstract

Value engineering is a systematic approach that aims to analyze the functions of systems, equipment and services in a way that provides the required performance, quality and reliability at the lowest cost. In the study, a change in the design and material of the house type top gas cooktop component was made with the value engineering approach. Function analysis, cost analysis, function-value-benefit analysis were performed at the beginning of the study; by this way, it was decided that component cost improvement would be made at which cost improvement. In the next stage, cost reduction was realized by making the gas taps from aluminum material instead of brass material and by making design improvements to reduce the amount of aluminum material used in the burner room by 10%. In the study, it was observed that the use of expensive and high amount of materials caused a cost increase. On the other hand, process faults caused by brass burr were prevented from at the aluminium taps and combustion efficiency was increased over 6% in burner rooms designed by reducing aluminum usage amount by 10%.

Ev Tipi Set Üstü Gazlı Ocaklarda Maliyet ve Kalite İyileştirme Amaçlı Bir Değer Mühendisliği Uygulaması

Öz

Değer mühendisliği sistemlerin, ekipmanların, hizmetlerin fonksiyonlarını en düşük maliyette gerekli performans, kalite ve güvenilirliği sağlayacak şekilde analiz etmeyi amaçlayan sistematik bir yaklaşımdır. Çalışmada Değer Mühendisliği yaklaşımıyla ev tipi set üstü gazlı ocak aksam tasarımı ve malzemesinde değişiklik yapılmıştır. Çalışmanın başlangıcında fonksiyon analizi, maliyet analizi, fonksiyon-değer-fayda analizi yapılmış; bu sayede hangi aksamda maliyet iyileştirmesi yapılacağına karar verilmiştir. Sonraki aşamada, gaz musluklarının pirinç malzeme yerine alüminyum malzemeden üretilmesi sağlanarak ve bek odasında kullanılan alüminyum malzeme miktarının %10 azalmasını sağlayacak tasarım iyileştirmeleri yapılarak maliyet azalışı gerçekleştirilmiştir. Çalışmada pahalı ve yüksek miktarda malzeme kullanımının maliyet artışına neden olduğu gözlemlenmiştir. Öte taraftan, pirinç yerine alüminyumdan üretilen muslukta pirinç çapağı kaynaklı proses hataları engellenmiş ve alüminyum kullanım miktarı %10 azaltılarak tasarlanan bek odasıyla mevcut ocaklardaki yanma verimliliğinin %6 üstünde yanma verimliliği gerçekleştirilmiştir.
