Abstract�� The concept of activity-based quality cost was introduced, and the idea of describing the relationships among quality activities according to quality cost was discussed. The rules with which the activities acted on each other were defined. Because of the large amount of quality cost data, it was decided to apply the association rule mining technology to dig the relationships among quality activities. The association rule mining technology was emphasized, especially the Boolean association rules mining technology, which was used in the mining process. Applying Apriori algorithm,and using quality cost data and the trend of their changes, the model of the quality activity chain based on activity-based quality cost could be set up. This model can be used in the estimation and analysis of quality cost to find out the bottlenecks in quality management process from the economic view, and to provide effective ways to make decisions on quality improvements.
