Abstract :
The qualitative evaluation of the products of organizations and economic enterprises in order to achieve a sustainable strategy and increase the sales share in the competitive market is one of the most important strategic plans of any company. Silica sand is one of the most widely used materials in the industry, especially in the casting industry. The purpose of this study is to predict the increase in quality for silica sands of foundry industries from the data obtained from the laboratory based on the design of experiments using the Taguchi method. In this research, based on the research literature and expert interviews, the Delphi technique was used to identify the investigated components, and the fuzzy AHP decision-making method was used to select the indicators effective in increasing the quality. Therefore, in this section, the ranking of these indicators will be discussed. And finally, by using the design of experiments by Taguchi method on two levels, it was determined that the indicators of acid, time, and weight-to-volume ratio have a significant effect in order to increase the quality.
