Fuzzy Logic and SPC

Part of the Studies in Fuzziness and Soft Computing book series (STUDFUZZ, volume 71)


The use of statistical process control (SPC) procedures such as Shewhart charts has been one of the pillars of the quality revolution. The Shewhart charts display process data under test and provide statistical decision making tools to assess the process quality (Shewhart 1931). These simple charting methods have proven to be powerful tools for monitoring the ‘health’ of a process, for detecting special causes and events, and showing if the process in under control. In quality monitoring (Box and Luceño 1997) applications of process industry we must often use uncertain measurements and SPC is a good tool for handling them.
