This paper considers the economic statistical process control for two dependent processes with two failure mechanisms which obey weibull shock models and have increasing failurerates 摘要本文提出相依子制程有两个递增失效率机械的制程管制方法。
Participate in the implementation of effective process control , product handling and packaging , product identification , control of non - conforming materials and statistical process control 执行有效的过程控制,产品的处理和包装,对不合格材料及统计过程进行控制
2 . conventional analytical methods used in multivariate statistical process control , such as principal component analysis , multi - way principal component analysis are summarized 2 、对多元统计过程控制常用的分析方法进行了介绍和总结,如主元分析、多向主元分析。
Basic statistics : blue - collar workers on an assembly line successfully use statistical process control techniques ; powerful statistical techniques do not have to be cryptic and arcane 基础统计学:装配线上的蓝领工人成功地使用着统计过程控制技术;强大的统计学技术并非神秘不可思议的。
Of course , it is often effective to apply conventional multivariate statistical process control ( mspc ) to the process whose process variables are subjected ( or approximatively subjected ) to multivariate normal distribution 本文的研究正是着眼于克服这两大假设条件,使过程监控技术能更好地适用于实际工业生产过程而进行的。

The principle and soft - sensing model of these parameters are studied and applied in the software . 3 . the multivariate statistical process control is used to monitoring the performance of fermentation process 分析了抗生素发酵过程中具有重要意义的软测量参数,研究了这些参数的机理和软测量模型,并在“发酵过程优化操作控制系统软件”中进行了应用。
It is pointed out that fault diagnosis based on multivariate statistical process control has the advantage of no needing of accurately modeling and little effect from the strong correlations among the industrial variables 指出了基于多元统计过程控制的故障诊断方法具有不需要精确建模、受工业变量间强耦合关系影响小等优点,并概述了其现状及发展趋势。
The main research work includes as following : 1 . firstly , we introduce the concept and technique of spc ( statistical process control ) , summarize the application and development of spc and sum up it ' s characteristic 简单介绍了统计过程控制的基本概念以及其类型和基本方法,综述统计过程控制的应用与发展现状,概括了其发展特点,概述了本文的研究内容。
Statistical process control (SPC) is a method of quality control which uses statistical methods. SPC is applied in order to monitor and control a process.
