Abstract: Total cost of quality plays a remarkable role in all companies so they use this information of quality cost to achieve some aims: first of all to improve the quality, to control the quality cost and last but not least to have effects on profit. In the context of management, rough set theory is one of the new ways which is used to analyse the quality costs and determine the crucial indicators of quality. Rough theory is used to collect information about the cost of quality of 11 reputable companies which are active in bourse Iran and belong to the ceramic industry over a period of five years and finally, three high-performance rules have been formed so that managers can use these rules in the industry to analyse the current situation and anticipate the future.
