应用关联规则构建质量活动链模型

介绍了作业质量成本的概念,提出了以作业质量成本数据为基础描述质量活动间关联关系的方法,并设定了作业质量成本之间相互影响的规则.着重研究了关联规则挖掘技术,将布尔型关联规则用于质量活动间作用关系的挖掘,并应用Apriori算法,研究了应用作业质量成本数据及其变化趋势构建基于作业质量成本的质量活动链模型的方法.该模型有助于在质量成本预测与分析过程中从经济的角度发现质量管理过程的瓶颈问题,为以质量成本分析为基础,系统地进行质量改进决策提供了有效的方法和手段. 

Association rule mining algorithm in modeling quality activity chain based on quality cost data

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.
