Patent Document ID: 7805394
Application ID: 12428529

Base Claim:
1. An apparatus for the analysis of a process having parameter-based faults, comprising: a parameter value inputter configured for inputting values of at least two process parameters; a learning file creator associated with said parameter value inputter, configured for generating a set of said input values obtained during normal process behavior and for creating a learning file for said set of input values, wherein said learning file is arranged for joint statistical analysis of said at least two process parameters; a learning file analyzer associated with said learning file creator, configured for performing a statistical analysis of said learning file so as to detect constellations of parameter values indicative of a fault, thereby to assess a process status; and process monitor associated with said learning file analyzer, configured for monitoring parameter values of an ongoing process so as to determine a current status of said ongoing process, and to provide alerts to a process operator in accordance with said current process status.
