Abstract : Cushioned by its significant oil reserves and promising economic development projects including the establishment of six economic cities across the kingdom, Saudi Arabia has witnessed an unprecedented growth in the building and construction industry. This led the tremendous increase in the demand of paint. Techno paint is one of the industry having increase market competitiveness in price and quality. In this research the component of paint is studied to reduce its price by maintaining the quality. Paint composed of water, resin and Titanium oxide. In this research Aluminum Silicate is introduced to replace the Titanium oxide to check its effects on wash ability, gloss, obesity (hiding) and cost. The well-known technique of six sigma methodology DMAIC is used to improve the paint quality. The problem of the Techno paint industry is defined and in Measure phase the computer generated experiments are generated. Design of experiment with different level is used to analyze the results of different levels of input on output variables. Total 19 experimental combinations of input variables (resin, water, TiO2, AlSi) were generated and their results are measured on output variables (Wash ability, Gloss, Hiding and cost). The amount of TiO2 is decreased from 25 to 17 and Aluminum is increased from 0 to 8g. In analysis phase the effect of correlation test is performed to check the relationship between input and output variables. Regression analysis is used to develop the equations for each output variable which later on used in mathematical model of goal programming to optimize the price. The results show that the lowest cost of paint is achieved at the level of 17g and 8g of TiO2 and Aluminum Silicate respectively. The optimized ingredients reduced the cost per barrel of paint to SR 13.13337.
