Abstract:
The objectives of this research are to find the cost of quality and to study the expenses incurred in the factory by examining the part of Set Top Box products and by emphasizing the part of capital that results from maintaining the quality of products. Additionally, the quality cost relation model was created for using to predict the quality of the production of the electronic components and to guide of selection a quality system that are caused the greatest losses in manufacturing. An analysis of the guidelines to improve the quality system was evaluated from the quality cost relation model, using a multiple linear regression analysis. The model was applied from comparative analysis of quality cost of relation model before and after adjusted result indicating the changes in the relation of the costs of quality after adjusting. In addition, there were found quality cost of relation model before adjustment is IFC = 7.915 3.979PC + 2.183 AC and after adjustment is IFC = 16.984 14.572 PC 1.316 AC. These show that the effect of the quality system improvement which has been changed in a way for accurate and appropriate results in the factory. This research has improved the quality system based on improved quality-related activities by choosing activities that produced the highest waste used as indicators for improving the results. Because of the occurrence of waste from the production processed are main factors to make high cost of quality. The result from this research shows that the factory could install the cost of quality system to understand the capital production in quality processes and control quality system. Based on the analysis, the scrap quantity of set top box was reduced to 57.18% from volume of the original waste. Therefore, the total cost f quality was also reduced to an average of 21.27% from the original.
