By using simulation and positive analysis, we have proved that these procedures can solve the multivariate process control problems well . in this field, some innovation results are obtained 通过大量仿真和实证分析证明,这些方法在不失相关信息的情况下,较好地解决了多元质量控制及诊断问题。
Industrial process monitoring has developed for seventy years from first appearance of quality control diagram by shewhart, however, the research for multivariate process monitoring is only longer than ten years 工业过程监控技术从单变量过程监控算起,已有近七十多年的历史,但基于多变量信息的过程监控技术至今也不过十几年的时间。
In this paper, three new procedures are provided to assess multivariate process capability . that is cumulative non-conformity rate method, principal component method and composite index method . it can be proved that our procedures are very useful in assessing process performance by using some positive analysis 本文从过程能力指数的机理出发,提出了评价多元质量特性过程能力的3种方法,即累计不合格品率法、主成分分析法和复合能力指数法,并进行了若干实证分析,这为评价多元质量特性制造过程的能力进行了有益的探索。
