SPC(Statistical Process Control)统计过程控制,最早由贝尔实验室的W.A.休哈特博士在1924年提出并应用。经过近90年的发展,已经成为质量管理最常用的方法。在实践中,由于SPC需要大量的数据处理和数理统计,对人员的技能要求很高,并需要花费大量的时间精力,而且人工计算还存在较大的失误风险。因此,在1970年代后,计算机逐渐进入大工业制程应用后,涌现出许多软件来辅助人们进行SPC计算。这些软件利
SPC (Statistical Process Control) Statistical Process Control was first proposed and applied by Dr. W. A. Shewhart of Bell Labs in 1924. After nearly 90 years of development, quality management has become the most commonly used method. In practice, SPC requires a lot of data processing and mathematical statistics, which requires high skills and requires a great deal of time and energy, and there is a big risk of mistakes in manual calculation. Therefore, after the gradual introduction of computers into large-scale industrial processes in the 1970s, many software emerged to assist people in SPC calculations. These software benefits
