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

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%
