Abstract
A statistical process control information system includes a process information system (process IS) and an analysis information system (analysis IS). The analysis IS generates a script file and a command file. The script file includes responses to command-line queries generated by a process data extraction program, and the command file includes commands for invoking the process data extraction program and copying an extracted data file to the analysis IS. The analysis IS issues a command to the process IS to execute an extraction command routine, causing the process IS to copy and execute the command file. The analysis IS performs statistical analysis on the extracted data file and creates graphical SPC chart files, including a hypertext summary, and these are posted in a network-accessible database for users.
