( 1 ) how to accurately transmit the measured data of the on - line different process to computer through rs485 bus , it is called the statistical process control system of the spc ( statistical process control ) computer ( 1 )如何将生产线上不同工序的检测数据通过rs485总线准确可靠地传送给它们的上位机,被称作spc ( statisticalprocesscontrol )计算机的统计过程控制系统。
New resources and new investment in the latest computer aided design and engineering facilities , in statistical process control and many other leading edge disciplines ? are ensuring that for aston martin , the future is every bit as bright as its illustrious past 投资利用最先进的电脑辅助设计和制造设施,统计流程控制和其他最尖端领域的技术保证阿斯顿马丁的未来就像辉煌的过去一样充满光明。
By synthetically applying the method of cluster analysts and of parametric test and combining with the traditional means of statistical process control , a highly automatic controlling frame suitable for multi - variety and large quantity machine building process was pot forward 综合运用聚类分析和非参数检验的方法,结合传统的统计过程控制手段,提出了适用于多品种、大批量的高度自动化机械制造过程控制框架。
At the beginning , in this paper we talk about some background of quality management and statistical process control , and then point out and analyze some defects of shewhart control that had been used widely . a simple but effective method to aid in design control schemes is presented 本文首先介绍了质量管理和统计过程控制的背景知识,指出当今使用最为广泛的休哈特控制图的缺陷,提出一种设计控制图的简单有效的方法。
At the same time , the thesis commentates on the future of the efm . finally , the core business processes of quality management , process ability analysis and statistical process control are implemented using power builder 8 . 0 and sybase adaptive enterprise server 11 . 5 database 最后,用powerbuilder8 . 0和sybaseadaptiveenterpriseserver11 . 5数据库实现了设计中的主要业务、完成了关键生产过程的能力分析以及统计过程控制等。
On the basis of theoretical research , the statistical process control system is studied and developed , in which the traditional shewhart control chart and the method presented in the paper are employed , the functions of quality analysis and real - time control are realized 该系统应用了传统的休哈特控制图和本文提出方法,实现了对不同批量生产条件下的质量分析与实时控制,实现了数据分析、报警、报表输出等功能,并用实例进行了验证。
The work in this thesis is based on three technologies of multivariable statistical process control ( mspc ) , the principal component analysis ( pca ) , the partial least squares ( pls ) and the kernel density estimate ( kde ) . the work involves the following contents 基于多元统计过程控制方法中的主元分析法,偏最小二乘法和核函数分析法这三种技术,本课题主要研究了以下内容: 1 )用面向对象的方法开发多元统计过程控制状态监测应用系统。
Single variable statistical process control ( svspc ) and mspc are both spc , the shortage of svspc is that it only notices the value of one variable at some moment , not suiting to analyze the multivariable process data with interrelation among them 统计过程控制包括单变量统计方法和多元统计方法。传统的单变量统计过程控制技术的局限性在于仅注意监视某一时刻的一个质量变量或关键过程变量,不适合分析变量间存在相关特性的多变量过程数据。
The method to apply the statistical analysis theory in supervision of quality of product in manufacture process is statistical process control ( spc ) , which is the effectual tool to get eligible product and the foundation for supervising process performance and fault diagnosis 应用数学统计分析理论对生产过程进行产品质量监视和控制的方法称为统计过程控制( spc ) 。统计过程控制是获得合格产品质量的有效工具,同时也是过程性能监视和过程故障诊断的基础。
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.
