Course: Statistical Process Control


时长/Duration: 2 days

语言/Language: CN/EN



SPC is the abbreviation of statistical process control. It is a process control tool that uses statistics methods. As one of the five quality tools, SPC was originated from the United States in the 1920s. Over a past century, it has spread all over the world and has become one of the most classic tools in the field of quality management. In China, SPC has been widely used in manufacturing industry, and gradually has made its impact in other industries as well.


Based on the systematic introduction of SPC principles and tools, this course takes real cases as the starting point to explain the specific operation steps of SPC in simple terms, so that every participant can master this tool from the core.



SPC是统计过程控制(Statistical Process Control)的缩写,是一种借助统计学方法的过程控制工具。作为质量五大工具之一,SPC于19世界20年代诞生于美国,近一个世纪来传遍世界各国,成为质量领域最经典的工具之一。在我国,SPC已经广泛应用于制造业,并逐渐在其他行业产生影响。




Target Audience

Middle to senior technical and management personnel in the field of quality, production and technology.
